Hi everyone,
I just received my brand new R56, 3 weeks ago and I am loving it so far. I have however noticed that especially in 2nd gear the engine seems to be rev up nicely but without putting that power down to the wheels and then on 3rd gear the acceleration is there. I have DSC on but the warning light doesn’t flash as if its trying to restrain the wheels form spinning. I ve also tried with DSC off and the same thing happens as well.
It almost feels as if the clutch is slipping. Is it possible that because the clutch disc is new (only 900 kms on the clock) that they cant take the power yet?
Has anyone else experienced this?

Any comments or views will be greatly appreciated.

With all the torque the MCS has keeping the power on the road is a problem when you gun it. Lead foot will always cause wheel spin . LOL If you think the clutch is a problem take it back to the dealer.

Hey cco7ers,l thanks for the reply, I do realise there is alot of torque to deal with but is there a way I can test this due to the clutch or not before going to the dealer?

I feel the same stratius, in my R56S with nearly 3000 miles I feel that the car seems to accelerate faster in 3rd than 2nd. Not sure if this is perception, but does seem strange

Hey Dainewb, I ve noticed that if I press softly on the throtle at first until 2,500 rpm on 2nd gear and then gradually increase pressure, the car responds better but when I press hard on the throtle from the beginning the revs go up fast up to 4,000 rpm but without the equivelant acceleration and without having any indication that the DSC has kicked in. I have the impression that the car didnt do that at first, but I sure do feel it does now.
Is it the same with you?

To check for clutch slip; stop the car, apply the handbrake really hard, engage first gear, give the car some revs and start to engage the clutch. If the clutch is slipping the revs will probably die down a little but it wont really feel like it's going to pull the car.

TBH though if you were having a slipping clutch you'd notice problems on hills, or ramps in car parks and it would be most noticable in first gear.

yes i think i agree with this, but is something quite hard to put my finger on! Coming home from work today i was at the lights on a good road and accelareted hard through 1st and 2nd and found it pretty impressive! probably only joined 2nd at higher revs.

Perhaps it is just a matter of getting used to the car. It certainly takes more thought to drive than my old cooper to get the best out of it. Not sure mine has a problem necessarily. A friend of mine has a focus ST and they recommended applying the throttle more gently at first to get better acceleration.

I suppose what is strange and what you are driving at, is why when on an ocassion when the stability control does not kick in even when you floor it in second, does it seem to accelerate less quickly than when you apply the throttle more progressively.

I have no idea! (but I know nothing about the engineering side of cars!)

On my tuned S (R53) I notice that there is an obvious backing off of the throttle at times but the ASC/DSC light does not flash. It's only ever under full throttle acceleration so it must be this system backing it off.

Maybe it's the same on the R56. I never noticed my Cooper Works doing it but maybe 140BHP wasn't enough power for it to occur.

Sounds like you are gradually building up the boost, hence the response is then fast as there is boost available.

Boost is not instantaneous, go drive an old turbo diesel for a while, you'll soon get the idea (and appreciate how good the MCS is)
