* Vectra OPC and Vectra OPC Station Wagon: 188 kW/255 hp 2.8-liter V6 turbo unit
* Combined market launch in Germany on November 25

Four new OPC models (Opel Performance Center) show just how much sporty potential and technological expertise is built into Opel cars. At the same time, the Astra, Zafira and Vectra high performance versions highlight the company?s strategy to spark emotions with its products and set standards in driving dynamics.

OPC engineers have further developed the inherently sporty Astra GTC into a high performance hatchback. A 177 kW/240 hp 2.0-liter gasoline turbo engine ensures exciting driving, accelerating the coupé-like model to 100 km/h in 6.4 seconds and taking it to a maximum speed of 244 km/h. The chassis comes with IDSPlus (Interactive Driving System), a technology that electronically networks and coordinates all driving dynamics functions. In addition, the driver can choose an even sportier set-up by simply pressing the ?SportSwitch? button.

With exactly the same engine as the Astra OPC, the new Zafira OPC accelerates to 100 km/h in 7.8 seconds and reaches a top speed of 231 km/h. A trendsetter in interior flexibility thanks to its patented Flex7 seating system, the world?s fastest series-production van attracts demanding sports car fans who are looking for a particularly versatile car. It features the state-of-the-art high-tech chassis control system IDSPlus2, with further improved roll-prevention that combines precise handling and active safety with high ride comfort.

With the five-door Vectra OPC hatchback and the Vectra OPC station wagon, Opel presented two world premieres in the high performance mid-size class at the Frankfurt International Motor Show (IAA). Thanks to an output of 188 kW/255 hp from a newly developed 2.8-liter V6 engine with a twin-scroll turbocharger and variable valve timing, the OPC portfolio?s top models feature driving dynamics at sports car level. The sedan and station wagon accelerate to 100 km/h in just 6.7 seconds and 6.9 seconds respectively, and reach a top speed of 260 km/h (station wagon: 254 km/h). Like the Zafira OPC, both feature the enhanced IDSPlus2 driving dynamics control system.

The new OPC models are also eye-catchers, featuring distinctive front spoilers with a central air intake, large 18-inch wheels in characteristic OPC six-spoke design, strongly contoured door sills, blue brake calipers and exhaust systems with trapezoidal tail pipes. The interiors boast top quality Recaro sports seats and special sports instruments, as well as a leather-trimmed steering wheel and gearshift lever. The high performance versions offer a blend of exciting design, top-class technology and outstanding driving performance at an excellent price-performance ratio, sums up Alain Visser, Executive Director, European Marketing. ?The OPC models are cars that are perfectly suitable for everyday use, with a sporty character. At the same time, they embody the other key attributes of our brand, such as versatility.? Customers can see for themselves on November 25, when the OPC range goes on sale at Opel dealerships in Germany.

Overview: Technical Highlights of OPC Models

Forged aluminum-silicon pistons:
Lightweight pistons capable of withstanding high thermal loads.

Sodium-cooled exhaust valves:
The valves contain sodium to disperse heat more efficiently (sodium is a waxy alkaline metal with good thermal conductivity).

Drive-by-wire:
Sensory detection of gas pedal movement, realized via an actuating motor. Advantage: optimized drivability, smoother transitions.

Direct ignition with separate coils:
One coil per spark plug to build up a high spark voltage without losses.

Hot-film air mass measurement:
Precise air mass measurement irrespective of temperature and air pressure fluctuations, for optimal fuel-air mixture preparation.

Hydroforming:
A hydro-mechanical pressing process by which hollow components are shaped using water pressure. Advantages: lower weight, high strength, lower costs.

Interactive Driving System IDSPlus2:
Electronic chassis control, in which the dynamic drive systems (electronic stability program ESPPlus, traction control TCPlus, understeer control logic UCL, ABS anti-lock brake system, Brake Assist and Continuous Damping Control (CDC)) are networked as an interactive system. The second-generation system uses highly sophisticated control software to provide optimally precise suspension and rolling refinement.

?Low-end torque? engine characteristic:
An early, steep rise of the torque curve promotes spontaneous engine response and high flexibility.

Metal-monolith catalytic converter:
Metal-base catalytic converters have shorter ?light-off times? than ceramic catalytic converters. They also cause less exhaust back-pressure and have greater thermal stability and mechanical strength.

SportSwitch:
A switch that activates much more sporty suspension settings, with firmer shock absorbers and more direct steering and gas pedal response.

Oil-spray cooling:
Cooling of the piston crowns in engines subject to high thermal loads by spraying them with engine oil through special nozzles.

Twin-scroll turbocharger (2.8 V6 Turbo):
The exhaust-driven turbine is supplied with two separate exhaust flows, one from each cylinder bank. Advantages: the more uniform input-pulses optimize response, power delivery and the efficiency of the turbocharger.

Turbo system, integral (2.0 Turbo):
The exhaust manifold, turbine housing and waste gate are located in a single component. Advantages: less weight, less installation space, better response.

Variable valve timing (2.8 V6 Turbo):
Depending on the engine-load and driving conditions, the inlet valve opening/closing angles are varied, resulting in an unrestricted power flow at high engine speeds and plenty of pulling power at low speeds.

The New Opel Astra OPC
Compact Sports Car

* 177 kW/240 PS two-liter turbo engine with 320 Nm torque
* Acceleration 0 - 100 km/h in 6.4 seconds, top speed 244 km/h
* IDSPlus with electronic damping control CDC standard
* Market introduction in Germany on November 25

With the new Astra OPC, Opel is penetrating far into the segment of established compact-sized sports cars. Corresponding performance provided by the 177 kW/240 hp 2.0-liter turbocharged gasoline engine that accelerates the coupé-shaped three door hatchback from 0 to 100 km/h in 6.4 seconds, and gives it a top speed of 244 km/h. A close-ratio six-speed manual gearbox transfers the power to the front wheels.

Apart from the driving performance, the way the engine delivers its power is equally impressive. The maximum torque of 320 Newton meters is available even at low rpm and thus not only contributes to a sporty driving style, but also allows for comfortable cruising at low speeds. Fuel consumption of 9.2 liters per 100 km (MVEG-standard) is a clear sign of the engine?s efficiency.

Visually, the Astra OPC can also be easily identified as one of the most powerful front-wheel drive production cars in the world, and the image boosting, top-of-the-line version of the Astra model range. The bodywork, with its deep front spoiler and central engine cooling-air intake plus the large-sized 18 inch wheels with exclusive OPC six-spoke design (tire size 225/40 R18 Y), testifies to the dynamic potential of the car, as does the rear section with its centrally located tailpipe. The interior exudes high quality and driver-focus, with Recaro sport seats available in two leather/fabric combinations, sporty instruments in OPC design, and aluminum pedals all contributing to a sporty atmosphere.

The attribute ?high tech? also applies to the sporty set-up of the Astra OPC?s chassis. This features as standard IDSPlus (Interactive Driving System) with electronic networking of all driving dynamics systems including the electronic stability program ESPPlus, and traction control TCPlus , as well as numerous features of the 17 inch high performance brakes. All these systems are interconnected and harmonized with each other. Another major element in this network is the electronic CDC (Continuous Damping Control), that ensures that the damping characteristics are automatically and continuously adapted to the current road conditions, the movements of the vehicle and the individual driving style. Additionally, the driver has the possibility to select an even sportier setting by pushing the ?SportSwitch?.

Like all OPC-models, the Astra OPC stands out for its fascinating design, state-of-the-art technology and first-class driving dynamics, as well as extraordinary value for money. With prices starting at 28,000 Euros, the compact sports car represents a very competitive offer, especially as the standard equipment meets nearly every requirement, and the safety features are state-of-the-art, including six airbags, active headrests at the front and the PRS pedal release system.

Customers can order the Astra OPC since September, the dealer launch in Germany will be on November 25, 2005.

Design: power and emotion

The new Opel Astra OPC is based on the Astra GTC ? a real challenge for the design team headed by Ulli Hochmuth, as the original three-door model already features a very dynamic appearance. The new Astra OPC?s design is even more emphatic, reflecting the OPC design philosophy ? uncompromising sportiness in a distinctive design language.

The front of the Astra OPC is dominated by a deep front spoiler with a large, central engine cooling-air intake flanked by fog lamps in spot-light design. Unlike the vane design used in the Astra GTC, the OPC has honeycomb openings and intakes in the front spoiler and radiator grille.

The rear of the Astra OPC is also unmistakable, defined by the distinctive rear spoiler and centrally located trapezoidal tailpipe, a characteristic styling element of the OPC design language. The most striking features of the side view are the door sills, which are more prominent than those of the GTC, the blue brake calipers as well as the large-sized 18 inch wheels with OPC exclusive six-spoke design, fitted with tires in the dimension 225/40 R18 Y. Two different 19 inch wheels with 235/35 ZR19 XL tires can be ordered as an option. Bodywork colors to chose from are arden blue, star silver, sapphire black and magma red.

The cockpit is sporty and sophisticated, boasting matte chrome-ringed instruments with special graphics, a three-spoke, leather-covered sport steering wheel, leather-covered gearshift lever, door sill trims in OPC design as well as aluminum pedals.

Ergonomically optimized Recaro sport seats not only have an extraordinary fit with precise longitudinal and lateral support, they are also examples of the high-quality materials and meticulous workmanship in the interior. There are two standard fabric/leather color combinations to choose from (blue/black and silver/black); a complete leather variant (black) is available as an option. Customers can also choose décor strips in anthracite, silver or blue.

Engine: Powerful and efficient

The turbocharged 2.0 litre engine of the Astra OPC is the latest and to date the most powerful evolution version of the ECOTEC engine generation. Compared to the 147 kW/200 hp version from the Astra 2.0 Turbo, the OPC-engine with its 177 kW/240 hp has some significant modifications. Among these are oil-spray cooling and modified rings for the aluminum-silicon forged pistons, a pressure-optimized turbocharger, an intercooler with increased flow rate as well as larger fuel injection nozzles. A reduction of the engine rotating mass is achieved through elimination of the balance shafts, significantly contributing to the engine?s liveliness and responsiveness.

Another distinguishing feature of the four-valve engine is the integral turbocharger system, which combines the exhaust manifold, turbo housing and wastegate into one single assembly. This solution was first introduced in a production model by Opel in 1992 in the Calibra Turbo. The integral turbocharger system is not only lighter and more compact than conventional designs, it also makes a key contribution to the engine?s performance: the shortened gas flow paths between the turbine and the engine, as well as the use of a low-inertia turbine, result in what is known as high ?low-end torque?, an engine operating characteristic in which the torque curve rises steeply from idle speed, ensuring immediate response to even the smallest load changes.

Thus, at an engine speed of only 2400 rpm and a maximum boost of 1.2 bar, the torque curve reaches a top level of 320 Newton meters, which remains constantly and fully available up to 5000 rpm. The engine reaches its top performance of 177 kW/240 hp at 5600 rpm.

High tech is also dominating in the engine bay. Gas pedal movements are registered electronically (?drive-by-wire?) and mechanically implemented by a butterfly throttle actuating motor. The electronic engine management system features high-precision hot film air mass measurement, sequential fuel injection as well as separate-coil ignition with cylinder-selective knock control. A double catalytic converter with metal supports and two lambda sensors already ensures an effective exhaust air cleaning when the engine temperatures are still low.

Chassis: IDSPlus adaptive chassis control as standard

The Astra OPC also ows its attribute as a driving machine courtesy of its state-of-the-art chassis technology. The spring-damper system has been tuned to ensure a stiff, sporty and active feeling. Compared to the Astra GTC, the bodywork has been lowered by 15 millimeters. The stabilizer bearings have less friction and a higher preload, as well as adjusted steering-knuckle geometry. All these measures enhance roll-prevention and enable a more sensitive steering response, thus contributing to higher handling precision and neutral self-steering reactions.

The hydroforming process used by Opel, with which certain chassis components are pressed into shape using high hydraulic pressure, enables the use of a torsion-beam rear axle with double-walled U section, as well as efficient design of the wheel carrier assembly. This in turn allows for exact chassis tuning while retaining the advantages of a conventional torsion-beam rear axle (compactness, low weight, high camber stiffness).

The Astra OPC?s 17-inch, high-performance brake system, with internally ventilated front disks (diameter 321 x 28 mm) and solid disks at the rear (278 x 10 mm), provides powerful deceleration, durability and feel. The electro-hydraulic power steering features a specific OPC set-up to ensure best-possible road contact and precise response.

The chassis concept of the Astra OPC is being perfectioned by the driving dynamic control system IDSPlus (Interactive Driving System), networking and interconnecting all electronic driver aid systems, including the electronic stability program ESPPlus, traction control TCPlus, understeer control logic (UCL), ABS and the brake assistant.

Another major element in this network is the electronic shock absorber control CDC (Continuous Damping Control), that ensures that the damping characteristics are automatically and permanently adapted to the current road conditions, the movement of the vehicle and the individual driving style, thus optimizing traction and stopping power.

Additionally, the driver has the possibility to select the ?SportSwitch? mode for a consequent sporty handling or for excursions at the race circuit. This gives the shock absorbers, steering and gas pedal a more direct set-up. ESPPlus can be deactivated in special circumstances.

Given its dynamic potential, the Astra OPC not only had to undergo dyno tests in the laboratory of the International Technical Development Center (ITDC) in Rüsselsheim, but also a comprehensive real life test program, including set-up tests and endurance runs at the Nordschleife of the Nürburgring and at the Opel test center in Dudenhofen. One of the members of the test crew was Manuel Reuter, with two wins at Le Mans and more than 200 DTM races under his belt Opel?s most experienced works driver, whose vast experience contributed to the set-up of the high performance cars.

Key markets: Germany, Switzerland and United Kingdom

The development of the latest generation of the Astra OPC was carried out in a proven way as a team effort by the International Technical Development Center (ITDC) in Rüsselsheim and the engineers and designers of the Opel Performance Center (OPC). The car is being built at the Opel factory in Antwerp, Belgium, where the car is on the same production line as the regular Astra production models. The sales target within Europe is at approx. 3,500 units per year, some 80 percent of which to be sold in Germany (800 units), Great Britain (1,800) and Switzerland (300).

Like all OPC models, the Astra OPC is offering state-of-the-art technology and top-class driving dynamics, combined with excellent value for money. At a sales price of 28,000 Euros in Germany, the compact sports car is a considerably competitive offering in its performance bracket. Even more so, as the standard equipment in excess of the OPC-specific details is almost complete, including for instance a climate control system, a CD 30 stereo sound system with MP3-compatitble CD-player and six speakers, electronically adjustable and heated exterior mirrors, electrically operated windows, a shiftable and tiltable steering column, rear seat backs that fold forward in a 60:40 split and a central locking system with remote control.

The Astra OPC is also state-of-the-art in terms of safety. Standard are front and side airbags, active head restraints in front, head curtain airbags for front and outer rear seats, safety belt force limiters and pyrotechnic belt tensioners in front, PRS (Pedal Release System) as well as mountings for ISOFIX child seats in the rear.

The new Zafira OPC

A sports van with exceptional driving dynamics
* 177 kW/240 hp 2.0-liter turbo engine with 320 Nm torque
* Zero ? 100km/h in 7.8 seconds ? maximum speed 231 km/h
* IDSPlus2: The new generation adaptive chassis control system
* Market launch in Germany on November 25.

With the new Zafira OPC, Opel and the Opel Performance Center (OPC) have given their success model even more power. The exclusive characteristics of the world?s fastest series minivan: an as yet unrivalled blend of ?sports van? driving dynamics and variability, which is at the top of its class. A 2.0-liter turbocharged gasoline engine and a maximum output of 177 kW/240 hp constitute the dynamic element, powering the front wheels via a six-speed manual transmission. The power unit provides its maximum torque of 320 Nm from 2,400 rpm and accelerates the innovative sports van to 100km/h in 7.8 seconds. The maximum speed is 231 km/h.

The Zafira OPC?s unique sporty potential is expressed in its design: a deep front spoiler with large central engine cooling air-intake and fog lamps, 18-inch wheels in the exclusive OPC six-spoke design with a tire size of 225/40 ZR18 Y, accentuated side sills as well as a powerful looking rear end with trapezoidal tail pipes. As for the body paintwork, there is a choice of the following colors in addition to the OPC color Arden blue: star silver, sapphire black and magma red.

In the interior, top-quality Recaro sports seats (available in two fabric-leather combinations), a leather-covered sports steering wheel and a leather covered gear lever grip, aluminum pedals as well as sports instruments and door sills in the typical OPC design emphasize the vehicle?s exclusivity. The seven-seater combines this ambience with exemplary spaciousness and the unbeatable advantages of the patented Flex-7 seating system, whereby it can be effortlessly transformed within seconds into a six-, five-, four-, three-, or two-seater, without the problems of having to remove or store the seats.

The Zafira OPC?s chassis and suspension features, just like the engine, a consistently sporty character and offers high active safety reserves. A 17-inch high-performance brake system and IDSPlus2 (Interactive Driving System) play their part, the latter being the latest state of development of the highly developed driving dynamics control system. Within this system all driver assistance systems such as the driving stability control system (ESP), various brake functions and Continuous Damping Control (CDC) are integrated and harmonized with each other. The benefit: excellent handling and further improved suspension comfort. For even sportier handling, the driver can select the ?SportSwitch? mode for a firmer chassis set-up.

Besides an outstanding combination of dynamics and variability, the Zafira OPC offers ? at a base price of 32,500 euros ? an equally excellent price-performance ratio. Comprehensive standard equipment and safety features leave little to be desired.

The Design: Innovative and Trend-setting

For the Zafira?s appearance, the specific claim was to emphasize the sporty attributes from a functional basic shape. A task solved successfully by the design team headed by Project Director Ulli Hochmuth. The Zafira OPC can at once be recognized as being part of the OPC model family. A typical design feature is the deep front spoiler with the large central cooling air-intake, with fog lamps in spot-light design positioned in strikingly drawn-out shafts.

The side view of the compact sports van is that of a 15-millimeter lowered suspension (compared to a mass-produced model), 18-inch wheels in the typical OPC six-spoke design and more prominent door sills. Also typical for the OPC vehicles? appearance are the blue-painted brake calipers, which are distinctive on account of their wheel rims in the form of a star. The optical highlight is the powerful rear end with a prominent spoiler, a double flow exhaust system with trapezoidal tail pipes and an aerodynamic additional profile on the roof edge. As for the other OPC models, the body colors Arden blue, star silver, sapphire black and magma red are available.

In line with its appearance, the Zafira?s interior is both top-quality and sportily-functional. Door sill trims in the exclusive OPC-design and pedals made of aluminum set the tone, as do the matt chrome-ringed instruments with special graphics and red needles. Even the engine compartment offers a technical ambience. With a cylinder-head cover in the typical silver-blue OPC design, the turbo engine stresses its exceptional position.

As for individualization of the interior space, there is a choice of blue, silver or black for the décor strips, the door moldings and the dashboard support, from which result a total of eleven possible combinations of body and interior color. The practical three-spoke sports steering wheel and the short gear shift lever are leather-covered. The ergonomically optimized sports seats by Recaro make for optimized stops and relaxing long-distance journeys; they are available ex works in two cotton-leather combinations ? blue/black or silver/black.

The seven-seater sports car combines this exclusive and sporty ambience with exemplary spaciousness and the unbeatable advantages of its highly variable Flex7 Seating System, whereby the seven-seater can effortlessly and within seconds be transformed into a six-, fix-, four-, three-, or two-, seater, without the problems of having to remove or store the seats.

Engine and drive train: a distinctive character and superior engine power

With an output of 177 kW/240 hp, the Zafira OPC ranks worldwide among the most powerful series-built front-wheel drive automobiles (apart from the Astra OPC, equipped with the same engine). The 1.2 bar power unit attains its output peak at 5,600 rpm. The maximum torque of 320 Nm is available at a constant level and within an rpm range of 2,400 to 5,000 rpm, to the significant advantage of drivability and elasticity.

The Zafira?s 2.0-liter four-valve engine boost a special technical solution, which was first introduced in a production model by Opel in 1992 in the Calibra Turbo. This solution, also known as the integral turbocharger system, combines the exhaust manifold, turbo housing and wastegate into one single assembly, making it is lighter and more compact. It also makes a key contribution to the engine?s performance: the short gas flow paths between the turbine and the engine, as well as the use of a low-inertia turbine result in what is known as ?low-end torque?, an engine operating characteristic in which the torque curve rises steeply from idle speed, ensuring an immediate response to even the smallest load changes.

Further high-tech characteristics of the ECOTEC power unit are forged aluminum-silicon pistons with special piston rings and oil-spray cooling, a pressure-optimized turbocharger, an intercooler with an increased flow rate as well as larger fuel injection nozzles. Gas pedal movements are registered electronically and translated mechanically by a butterfly throttle actuating motor (?drive-by-wire?). The electronic engine management system features high-precision hot-film air mass measurement, sequential fuel injection as well as separate-coil ignition with cylinder-selective knock control.

In line with the Astra OPC, the engineers dispensed with the obligatory balance shafts in the Zafira OPC ? these are otherwise found in series? engines. A reduction of the engine rotating mass is achieved through elimination of the balance shafts, significantly contributing to the engine?s liveliness and responsiveness.

IDSPlus2: The Second Generation of the ?Adaptive Dynamic Chassis Control System?

With its combination of McPherson strut front suspension and torsion-beam rear axle, the Zafira OPC matches the Astra OPC?s basic set-up. Aside special spring- and shock absorber rates, rebound stop springs in the suspension struts come into operation, as well as higher preload and reduced friction stabiliser bearings and adjusted steering-knuckle geometry. These are measures that come together to convert the sports van?s performance potential into precise handling, neutral self-steering as well as high active safety.

The 17-inch brake system plays an active role in this with internally ventilated front disks (diameter 321 x 28mm), as well as solid disks at the rear axle (278 x 10mm). It guarantees deceleration rates rivaling those of a sports car, coupled with outstanding strength and feel. The electro-hydraulic power steering was designed by OPC engineers to ensure best possible road contact and precise response. Wheels measuring 8 J x 18 in the exclusive OPC six-spoke design, which are equipped with the standard tire 225/40 ZR 18 Y, ensure an optimized road grip. There is also the option of a 19-inch wheel set, combined with 235/35 ZR 19 XL tires.

The latest Electronic Control System technology is used on the basis of this precise chassis frame balance. It is a technology previously found only in small-scale luxury and exclusive sports cars and defines the best available technology in the compact class and compact van class respectively. The IDSPlus2 system networks all driving dynamics systems via CAN data busses into one interactive system. Part of this system are the driving stability control system ESPPlus, the traction control TCPlus, understeer control logic UCL, as well as the anti-lock braking system, Brake Assist and Continuous Damping Control (CDC).

The CDC system continuously adjusts the shock absorbers to adapt to prevailing road conditions, vehicle movements and driving style. The decisive step-up from IDSPlus to IDSPlus2 is due to the use of even more efficient control software. Not only braking stability, traction and handling precision benefit from the more accurate damping forces; so too do ride and suspension comfort.

The ?SportSwitch? mode rounds off the high-tech system. By selecting this mode, the driver has access to even sportier handling, with firmer shock absorbers and more direct steering and gas pedal response. Should the driver wish to do out without the support of ESP, it can be deactivated.

Like for the development of other OPC models, a top-notch motorsports pro lent his support to the test crews. With his typical meticulousness, Manuel Reuter, winner of two Le Mans races and participant in more than 200 German Touring Car Championship (DTM) races and the most experienced Opel works driver, brought to bear his extensive expertise to bear in chassis tuning.

Market Situation: An Exclusive Special Position

The development of the innovative sports van was carried out in close cooperation between the International Technical Development Center (ITDC) in Rüsselsheim and the Opel Performance Center (OPC). The vehicle was built in the Bochum works, jointly on a production line with the regular variants of the Zafira. Assembly of the OPC body components and the exhaust system was carried out ?offline? by hand. With regard to the Zafira?s production targets, around 2,200 units are planned per year, and of these around 2,000 for the core markets of Germany (750), Great Britain (750) and Switzerland (500).

At a basis price of 32,500 euros in Germany, the Zafira OPC offers ? alongside its outstanding combination of sporty dynamics and superior variability ? a highly competitive price-performance ratio, and all the more so as the standard equipment leaves virtually nothing to be desired. This includes not only the OPC-specific details, but also a remote-controlled central locking system, electrically adjustable and heated exterior mirrors, a roof rail and power windows. There is also a height and reach-adjustable steering column, air conditioning, a CD 30 stereo audio system with an MP3-compatible CD drive and six speakers. Another feature is the innovative Flex7 Seating System, the state of the art when it comes to variability and versatility.

The seven-seater sports car?s safety equipment is equally extensive. Standard are front and side airbags, active head restraints in front, head curtain airbags for front and outer rear seats, safety belt force limiters and pyrotechnic belt tensioners in front, PRS (Pedal Release System) as well as mountings for an ISOFIX child?s seat in the rear.

With the Vectra OPC in the five-door hatchback version and the Vectra station wagon OPC, Opel is entering the category of midsize sports cars with two vehicles. Not only do they represent the present performance peak of the Opel program, they also rank among the most powerful front-wheel drive cars. The Vectra high-performance models made their debut at the Frankfurt International Motor Show (IAA); they will be launched on November 25, 2005.

In both cases, they will be powered by a newly developed V6 high-tech engine with a 2.8-liter capacity, driving the front wheels via a six-speed manual transmission. Thanks to twin-scroll turbocharging and variable valve timing, the engine develops a maximum output of 188 kW/255 hp and a maximum torque of 355 Nm. Driving performance rivals that of a sports car. The hatchback and the station wagon require 6.7 and 6.9 seconds respectively to accelerate from zero to 100 km/h, while their top speeds are 260 km/h and 254 km/h respectively.

The Opel Vectra?s high-performance versions combine the styling of the recently re-designed model range with the distinctive OPC design language, resulting in an emotionally-charged, dynamic appearance. The expressive front is dominated by a deep front spoiler and fog lamps in spot-light design. The side view?s highlights are the large-sized 18-inch light alloy wheels in the exclusive OPC six-spoke design (tires: 235/40 R18 Y) and more accentuated door sills. The rear ends of both cars are characterized by prominent bumpers with diffuser-like outlines, discrete spoilers as well as twin exhaust systems with trapezoidal tail pipes. For the paintwork, there is ? as for all OPC models ? the choice of the following colors: Arden blue, star silver, sapphire black or magma red.

The side sills in the exclusive OPC design make for an comfortable ambience in the passenger compartment; the same goes for the exclusive OPC-sports seats by Recaro, which are available in two fabric-leather combinations, an ergonomic three-spoke sports steering wheel and a sports gear lever, both leather-covered; sports instruments, special colors and a speedometer up to 300 km/h.

In terms of sporty handling and high active safety, the Vectra OPC models are endowed with the latest development of adaptive chassis control system. All electronic driving dynamics systems are linked up with each other to form a complete system; this includes the electronic stability program (ESPPlus), the traction control system (TCPlus), understeer control logic (UCL), cornering brake control (CBC), various brake functions and Continuous Damping Control (CDC). For even sportier handling, the driver can select, via CDC, the ?SportSwitch mode?, with firmer shock absorbers and more direct steering and gas pedal response. A 17-inch high performance braking system offers deceleration rates rivaling those of a sports car.

Alongside exciting design, top-class technology and outstanding driving performance, the Vectra high-performance models also offer an excellent price-performance ratio. In Germany, the Vectra OPC is available at 37,800 euros, and the Vectra OPC station wagon is priced at 38,600 euros. In accordance with their top-of-the-line status, the vehicles feature, besides the OPC specific details, a comprehensive equipment and comfort package. Passive safety includes six airbags, active head restraints in front, a Pedal Release System as well as mountings for an ISOFIX child?s seat in the rear.

Design: Two expressive variants

The two top versions combine specific OPC design characteristics with enhanced stylistic featuring, which will arrive in the model year 2006 with the Vectra?s new edition. Completely re-designed, the front presents itself with the typical Opel crease in the engine hood, a distinctive bumper V-shape as well as headlights reaching into the fender panel and the front deck lid. OPC-specific are the deep front spoiler, striking fog lamps in spotlight design, as well as body openings with sheathing in the signature honey comb structure. Altogether a dynamic and emotionally-charged appearance.

The side views and rear end feature their own discrete design language ? the sedan rather sporty and classic, the station wagon is more present and powerful. In both cases, the large-sized 18-inch light-alloy wheels in the exclusive OPC six-spoke design, heavily drawn-out door sills as well as blue-lacquered brake calipers make for dynamic proportions and visual highlights. The rear views also express unmistakably the potential of both sports cars: bumpers with diffuser-like molded outlines, discrete spoilers at the rear opening (sedan) and at the edge of the roof (station wagon), as well as double-flow exhaust systems with trapezoidal tail pipes transmit clear signals.

The interior is likewise dominated by new design features and the characteristic OPC styling elements. Among the new design features are the dashboard?s improved surfaces and the door linings, a prominent scoop above the instrument cluster and rounded-off ventilation nozzles. Typical OPC-features are the sports seats by Recaro, available in two fabric/leather combinations (blue/black and silver/black; optional: black full leather), and a three-spoke sports steering wheel and a sports gear shift lever, both leather-covered. The buyer can chose between blue or silver stitching.

Other visual highlights are the matte chrome-ringed instruments with red needles and a speed indicator up to 300 km/h as well as special OPC side sills. As for the other OPC models, the paintwork colors arden blue, star silver, sapphire black and magma red are available.

Engine: V6 high-performance engine with turbocharger

A newly developed, 2.8-liter V6 engine made entirely of aluminum with a cylinder angle of 60 degrees is used in the Vectra OPC models. The engine, equipped with twin-scroll turbocharging and variable valve timing develops a maximum output of 188 kW/255 hp at 5,500 rpm. A maximum torque of 355 Nm is available between a broad speed range of 1,800 and 4,500 rpm.

?Twin-scroll? means that the exhaust gas turbine is supplied with two separate exhaust flows, one from each cylinder bank fed, as a result of which response behavior, power build-up and efficiency are increased. A wastegate regulating valve limits the four-valve engine car?s boost pressure to 0.6 bar.

The continuously variable phase adjustment of the two intake camshafts makes an equally important contribution: the said phase adjustment takes effect up to a crankshaft angle of 50 degrees. The powerful 32-bit Motronic engine management system is responsible for control and regulation, phase adjustment being hydraulic. The short-stroke engine?s construction characteristics are a sodium-cooled discharge valve, piston-crown oil-spray cooling, hot-film air mass measurement, direct ignition with separate coils and electronic throttle control (?drive-by-wire?).

The result: drive dynamics rivaling those of a sports car. Hence both the sedan and the station wagon require just 6.7 seconds and 6.9 seconds respectively to accelerate from 0 to 100km/h and have a maximum speed of 260 km/h and 254 km/h respectively. In line with this are the 7.5 and 7.8 seconds for the elasticity test in the range of 80 to 120 km/h in the fifth gear, which underline the vehicle?s engine power, making both long-distance journeys just as much an option as relaxed cruising tours.

But the use of the most modern technologies guarantees not only maximum driving pleasure, but also comparatively low MVEG total fuel consumption: 10.4 (sedan), 10.5 liter premium gasoline (station wagon) respectively per 100 km are a convincing evidence of the vehicles? performance fuel efficiency.

IDSPlus2: The revolutionary Adaptive Chassis Control System

Equally highly developed as the engine is the Vectra OPC?s chassis technology. The new Vectra generation?s overhauled chassis is an integral part of this; with the McPherson strut front suspensions plus friction-optimized stabiliser bearings in front and a kinematically-optimized four-link rear axle.

In terms of highly sporty vehicle handling with high safety reserves, the Vectra?s OPC versions have their individual suspension and shock absorber characteristics. The high-performance 17-inch brake system with internally ventilated disks (diameter 345 x 30 mm) as well as externally ventilated disks (292 x 20 mm) ensures superior deceleration. Specially adjusted power steering provides clear feedback on the driving condition, whereas 8 J x 18 tires (tire size 235/40 R18 Y) in the exclusive OPC six-spoke design ensure maximum lateral stability and cornering stability. There is the choice of a 19-inch tire in combination with the tire size 235/35 ZR19 XL.

The IDSPlus2 system, the latest state of development of the highly developed driving dynamics control system, provides protection at the highest level ? a system that defines the state-of-the-art in this vehicle category. The IDSPlus2system networks all driving dynamics systems via CAN data busses into one interactive system. Components of this system are driving stability control system ESPPlus, traction control TCPlus, Understeer Control Logic UCL, the four-channel anti-lock system, Cornering Brake Control (CBC), Brake Assist and Continuous Damping Control (CDC).

The fundamental step-up from the previous IDSPlus system to the present IDSPlus2 system is attributed to the use of even more efficient control software. All participating subsystems benefit from this, as even faster and more precise adjustments of the damping powers not only improve braking stability, but also traction, the turning ability and handling precision. At the same time, the chassis elements? honed responsiveness also contributes to tire and suspension comfort. The CDC system continuously adjusts the shock absorbers to adapt to prevailing road conditions, vehicle movements and driving style. In addition, by selecting the ?SportSwitch? mode, the driver has access to even sportier handling, with firmer shock absorbers and more direct steering and gas pedal response. Should the driver wish to do without the support of ESPPlus, it can be deactivated.

Manuel Reuter was one of the test-crew members for chassis and suspension tuning. Like for previous OPC models, the winner of two Le Mans races and participant in more than 200 German Touring Car Championship (DTM) races, the most experienced Opel works driver brought his extensive expertise to bear when it came to fine-tuning the high-performance vehicles.

Sales Target: Around 2,400 vehicles a year

The OPC-specific developments of the Vectra high-performance models were a joint project between the International Technical Development Center (ITDC) in Rüsselsheim and the Opel Performance Center (OPC). The vehicles are jointly built in the Rüsselsheim works, on a production line with the other Vectra models variants. Assembly of the OPC body components and the exhaust system is carried out ?off-line? by hand.

In terms of output volume, 1,500 sedans and 900 station wagons are planned. According to estimates by marketing specialists, the hatchback version will be distributed to the three core OPC markets, Great Britain, Germany and Switzerland, in the following numbers: 900 units (Great Britain), 200 units (Germany) and 150 units (Switzerland). For the station wagon model, the following numbers are anticipated: 400 units for Germany, 280 units for Switzerland, 150 units for Great Britain.

The Vectra OPC and the Vectra Station wagon OPC offer their top-class technology and first-rate driving dynamics at an extraordinary price-performance ratio. At base prices in Germany of 37,800 and 38,600 euros for the sedan and the station wagon respectively, the most powerful Opel models at present are also exceptionally alluring in price, particularly as the standard equipment (beyond OPC-specific details) is practically complete.

This includes air conditioning, a CD 30 stereo audio system with an MP3-compatible CD drive and six speakers, a steering wheel remote-control, electrically adjustable and heated exterior mirrors, power windows, a height and reach-adjustable steering column and rear seat backs that fold forward in a 60:40 split as well as a remote-controlled central locking system.

The safety equipment is equally flawless and state-of-the-art in line with Opel standards.

Standard are front and side airbags, active head restraints in front, head curtain airbags for front and outer rear seats, safety belt force limiters and pyrotechnic belt tensioners in front, the PRS (Pedal Release System) as well as mountings for an ISOFIX child?s seat in the rear.
