12.5 @ 119 is not exactly quick or fast and better times for the C63 will come. What it shows is this is not easy. It also shows the C63 is easily an 11 second car with drag rubber and really even street tires as a 2.4X 60 foot time is just poor traction and a bad launch.
With a 1.7X 60 foot which is well within reason one can expect times to drop by over a second. BenzBoost believes the stock C63 is capable of mid to high 11's at 121-122.
More details from the owner:
"With a full tank of fuel, pano roof, and standard seats it weighed in at 4,065 pounds. He is not skinny but he sure is fast!
I was only able to get in 2 runs last night due to track issues. It was a cool summer night and the temp was about 80 degrees. I ran 93 Fuel & Tires were around 23-24 pounds in the rear. The biggest issue is getting the car to launch properly. There is a lot of torque this car puts out. I have room for improvement but overall it was a great night. I will be running the car again and making some changes on my end and the car's end.
First pass - Sport + with ESP on, Suspension in Comfort 12.679 at 117.63 MPH
Second pass - Race with ESP on, Suspension in Comfort 12.506 at 119.14 MPH.
I let the car do all the shifting. I did not shift gears via the paddles."
People will no doubt compare these times to M3/M4 times achieved but we would like to remind everyone such comparisons are flawed due to the cars running on different days at different tracks. All direct comparisons thus far show the C63 is the faster car and it does make more power and torque.
It sure is heavy though.
