m3e90board.com: BMW Z4 M Coupe vs Audi RS4

RS4 is about 336 hp on the wheels

@bennychan again ....4wd lose drivetrain vs 2wd? Your grasp on english is at best, very poor. RS4 has a superior power to weight ratio 255 vs 241 for the Z4. Which is why I said the bmw did ok. 4wd will not sap 60 + bhp! noob.

it sounds like an airplane lol

This is on a straight. Try a race between these two cars on a track. RS4 = understeer all day!!

Couple mods and the Z would start walking, nice video Gustav!!! keep em coming!

Very very even. Only at the very top end does the rs4 very slightly pull ahead (at around 1.20), just as the drivers mention. One thing a lot of people don't realise is the rs4 actually produces a lot less than the factory advertised. It's been on many dynos and pulled only between 360-390bhp.

I agree but the comment is not strictly true. My RS4 produced 413. Others out there are under powered as a result of the oil buildup due to the FSI. One of the reasons I sold mine as once this becomes public knowledge you will be able to pick up an RS4 for buttons. Cant believe EVO said the RS4 was a sound investment.

Other things is not important. Listen to the RS4's engine. It's amazing and just like an airplane.

That isnt the engine..thats the runway surface causing that sound as it is slightly graded!

Actually it sounds better from outside the car from about 20 meters back. Mine sounded whiney and dull from inside, not like a straight 6 with a carbon box.
