I engaged ESP Sport this morning and noticed the car was noticeably quicker. From my understanding of the ESP Sport setting, it raises the limit for when the electronic traction control engages and reduces power. The Sport setting does not change the character or the output of the engine. So is it reasonable to conclude that the traction control was constantly engaging and retarding my ability to scare the crap out of myself? Has anyone else noticed this when engaging the Sport setting on the ESP?

its funny that you mention this. I noticed yesterday (because I had my window down for the first time since I bought the car) that TCS is always engaging! Even when the light isnt flashing - so i could see if you had it in sport setting, that TCS would be engaging less, therefore feeling more wheel spin/less delay on throttle-to-acceleration etc.

Do you know what else was different this morning? the 29F temperature in Houston. Which makes the C63 a li'l faster.

I am in Houston, TX. This was around 5:30 AM today.

The lower temps help, but this is different. I've driven the car since October and there have been temps at this level before, but it feels different. A lot livelier and more fun. It could always be the placebo effect...............

I think what you're feeling is that you gain more control with the car in sport mode.

I've recently used sport mode for the first time since I got my car (2 years) because there was heavy rain and traction control kept interfering every time I tried to accelerate. It may sound counter - intuitive to be driving in heavy rain with traction off, but it was getting hard to merge onto the freeway when traction control kept cutting off my power. In sport mode, however, I was able to drive like I normally do.

Exactly correct.

OP, as you progressively disable the nannies, you are reducing the car's propensity to cut power in the event of wheel-spin.

What u felt was largely in ur mind and maybe some more wheel spin to a much less extent.
I v been driving my c63 in off mode since day one unless its wet. An average driver would drive faster with on mode tbh

The average driver is also pretty poor, and often cannot detect sliding or wheel spin until it's far too late. We are talking america here. Merica home of the nascar.

I find myself driving the car in sport constantly unless im just going to cruise. I like it off all the way but with the blower it just has too much damn low end torque and the power is so instant it's hard to predict it in a turn. my driver skill is somewhere in between sport and off. Sport will keep me out of trouble and i know if i curb one of these hre's my wife will neuter me. It's her car after all.

Yea i got a mechanical diff in the rear plus KWs, which make it so much easier to put the power down in a turn when its in the off mode.
I wouldnt feel comfortable enough to push a factory one too much in a turn, surely i would end up not on the road anymore.

KIS007

Precisely my point. I did not realize how often the car was attempting to protect me from myself. With it in Sport mode I am enjoying my new found power.

Try ESP off, its even better lol

It's basically the first thing I do when i get in the car LOL

Anyone know what ESP means ?

Electronic Stability Program, it's traction control.

You're theory makes a little sense if you consider that when entering launch mode you have to be in Sport.
