A stock LP560 Gallardo is faster than the F13 M6 from a stop, roll, whatever. MotorTrend's recent drag race results for the F13 M6 show it is about a ~123 mile per hour car stock in the 1/4 mile. Fast, but not LP560 fast which has been tested up to 130 by magazines. Let's go with MotorTrend's own numbers which are firstname.lastname@example.org:
How many miles per hour will tune and exhaust bolt on modifications add to the M6? Let's give the benefit of the doubt and say it brings it up to a 130 mile per hour 1/4 mile car. Even against a stock LP560 in a 1/4 mile it should take well into fifth gear from a stop in a drag race for the M6 to start to pull away against the lighter all wheel drive LP560 which is easily up to a second quicker in the 1/4 mile than the RWD F13 M6 especially on the street with street rubber. By 130 miles per hour (or 210 km/h as shown in the video) where the 1/4 mile should be about ending, the M6 is already putting bus lengths on the LP560 and pulling like a freight train.
It's tough to draw any conclusion other than the LP560 is letting off to accentuate the PP-P tuned M6's performance for the video. Especially considering how the LP560 gets its lead and then all of a sudden right before 130 miles per hour hits the M6 flies by as if a 200 shot of nitrous was hit when it should be a slow and gradual pull between these two.
This is an example of a video being misleading and why supporting data is necessary. Timeslips from the M6 would be great to have. There's a VBOX shown in the video, show us the data.
For some reason it is usually videos from Russia or overseas where performance is not backed up with timeslips that we get videos showing absurdly large differences between cars likely either for forum bragging rights or tuner promotion.
