I have a 03 996tt stock and my brother has a new bmw m5. we raced a couple times and I beat him every time,not by much maybe half car length. so that video of m6 and m5 racing a 996tt does not seem right.

 

The M6 is faster than the M5.

As far as M5 vs 996TT (stock), it will depend on the cars and the drivers. They are very close in a straight line.

 

I've couple video from last year with M5 and stock TT

TT have traction problem at 2nd gear, M5 at P500 sport mode

M5 at P500 non-sport" mode

both car were very close in stright line. At P500 sport mode. M5 can walk away slowly after 200km/h.

 

from what speed to what speed. depends on how many miles on his car also what setting he had during the race. i can only say the M5 is very fast on higher speed.

 

Stock TT having traction problems in 2nd gear???

 

I've had four 996tt's. None of the stock ones could run with my M5.

 

Why does it depend on his mileage

 

all i remember was my 300 miles M5 felt much slower than my 3,000 mile M5.

 

I think because by 3,000miles you had the 500 mode unlocked

 

i never thought there was a ''lock'' in power or at least i couldn't feel it. but car was definitely feel much smoother & faster after break in.

 

The "S500 sport" mode was unlock after first services. I've try before the 2000km services and you can't find S500 sport there, only S500. After couple runs with other cars, S500 sport and S500 is huge different in speed.

 

The M engines get faster with time.... This is true of all cars, but especially so for the 8000 RPM + M Engines.

 

The S54 from the e46 M3 really comes alive after about 10,000 miles. These engines (M Engines) really need to be broken in well. If they are you are rewarded very well later in the cars life.
