A blue RS4 sedan vs a Titanium Silver M5, both with wintertyres. 

Some key points below:

"Driving the M5 in the snow is effortless and a childs playthanks to it's electronics sensors"

"The engine of the M5 cannot be compared, there is nothing you can compare it with. So much of Jekyll and Hyde -at the same time!"

Weight of the M5 as tested: 1970 kg. 0-100 km/h in impressive 4,73 s

Weight of the RS4 as tested: 1870 kg (!). 4,67 s.

At 130 km/h the M5 will pass the RS4:

M5 0-200 km/h: 13,7 s
RS4 0-200 km/h: 15,65 s

0-402 m M5: 12,68 s and 192,4 km/h
0-402 m RS4: 12,86 s and 180,6 km/h

The BMW M5 and RS4 was dynoed on a Rototest notice that the RS4 lacks approx. 17 HP, clocking in at 403 HP. The BMW M5 gave 3 additional HP (510 HP) when measured.

RS4 averaged 1,5 liters / 10 km and M5 1,7 liters / 10 km

Bottom line: "We cannot say which is best since they are so different, but the Audi takes a lot of points on the winterroads."

"You can wait a few years to let them depreciate to half. And buy both" (not a bad idea  )

Summary for the RS4 "Class bully":

In many years Audi have tried to build a car that matches the best in power and not at least driving dynamics. With the new RS4 they have built that car -on all surfaces. Best in class.

Summary for the M5 "Megalomaniac":

Big, heavy and reasonably comfortable, and along with a competent driver can drive the xxx of most car there is. M5 might be the most impressive car in it's kind. Hightec in a way that no other has.

Both cars scored 61 points /100.

1970kg per la M5 mi sembrano troppi, se non erro viaggia a malapena sui 1800

muoverei un appunto su un dato tecnico

ma taccio  ;)

Cosa ? Se la M5 riesce a fare lo 0-200 in quel tempo piu' di 6 volte ?  :P ;D

Più che altro non capisco il senso del confronto, appartengono a segmenti diversi, hanno prezzi diversi, potenze diverse, trazioni diverse, numero di cilindri diversi, cambi diversi. Mistero.

si,ma un potenziale acquirente potrebbe valutarle..forse era meglio provare M5 e RS6,ma la RS6 è molto meno sportiva e solo un macchinone da autostrada a 250 costanti
