Are you sure that that was faster than the RS4 0-60?

I have already tried the 4.2 Audi, it revs up!!!. but, I did not feel any type of acceleration (strong push in the seat), surely there is little torque for the weight

0-60 in 4.5. What on Earth are you used to that that doesn’t feel reasonably brisk?

So no faster then.

don't think so, but the feeling has nothing to do between my car and the RS4. not everything comes from 0-60.
otherwise why do people mention the c63 feel more fast and strong than the rs4 or m3? the numbers 0-60 are close

manual gearbox for both, I don't look at the 0-60 I go in and I feel that's all. My car feels much faster on boost than rs4. It also feels faster than the GT3 991 I was a passenger in 3.4 0-60. even if it is not. stock rs4 b7 has around 380-400hp at the crankshaft. I mentioned 405hp at the wheel for my old r33

The feeling of acceleration does. That’s literally what is pushing you in the back.

I had an RS4, and a C63. Perhaps what you are trying to describe is that the Mercedes pulls better from lower revs, so if you are in the “wrong” gear then the Mercedes can feel faster.

My current “sensible” car is a 650bhp Range Rover Sport. 0-60 in just under 4 seconds, and feels it.

[Turbinox]

it's true and false, you feel the rate of change of acceleration (jerk) a ferrari f40 does a 0-60 in 4.5s many cars are faster murcielago, mclaren f1 etc but the feeling of acceleration of the f40 outperforms this car can import the numbers. all this due to the power delivered. I don't drive a C63 but according to people they push you back in the seat more than the RS4 absolutely. low revs, mid revs, high revs. just the much superior torque.

405 WHP is very different to the manufacturers crank bhp figure

[Turbinox]

humans are naturally worse at feeling constant acceleration compared to changing acceleration. the torque which increases sharply during boost creates a positive jolt, acceleration is better perceived than with a flat torque curve. this is why the laggy turbos feel very fast and offer the famous "turbo shove. Someone correct me if I'm wrong?

you who have driven a c63, the acceleration figures with the rs4 b7 or rs5 are close on the 0-60 but the feeling of acceleration is not the same? if you have driven one obviously

many options were supercharged or high revs. so off topic for now

and I don't reject everything I keep:
63 amg
5.5 e500 clk 500 m273
m5 e39
quattroporte 4.7

Only one in that list I've driven is the E39 M5 and, while it's a lovely car, I don't think it meets the brief in terms of pinning you back in your seat as the power delivery is too smooth. The technical term for what you are looking for is "jerk" but Googling that just turns up a lot of people with broken cars

As has been mentioned it's Jerk, the rate of change of acceleration.

thanks for the information on the m5.
I would think that with all this torque despite the smooth power delivery ( no jerk) but you would be pinned in the seat back

It doesn't accelerate as fast as a V8 M3 so I don't really understand why you think it will feel faster!!

[biggbn]

Going against the flow here, but Cayenne 4.8 GTS? Stonking engine, not nearly as quick as some of the other kit suggested but quick enough, practical and a little different. Failing that your answer has a Lexus badge!!

Never driven one but always thought the Jaguar Xfr-s was a great looking car even if supercharged.

Evo seemed to really rate it!

great car!!! but i'm only looking for na

Which is going to make the shove you are looking for a lot more difficult to find?

Looks like the MB 6.2 is going to be your best bet.

More torque and a less peaky power delivery I would guess?

That would be the direction that I'd go in if I was the OP as well.

If he's after ultimate shove and being pinned in his seat I can think of a car for £30k that offers that in spades. Doesn't have a gearbox or any cylinders though..

couldn't test a 63 AMG near me, I went to see a 2011 Camaro SS.
6.2 engine. (LS) there was a magnaflow exhaust + stage 1 remap.
The owner also removed the cylinder deactivation system. I don't know how this compares to a (stock) C63, but the weight and power are close. I didn't really like it, there was torque, a good sound but the power delivery was just very linear and without surprises. the shove was there but not as intense and fun as I thought
