'Battle of the supercars' was the first one to use an official Lexus LFA launch control spin, which minimizes wheelspin and maximizes traction for fast starts. Officially, yet never had Lexus' 3.6 seconds 0 - 6 mph had been shown in tests.

However, again this was the first time launch control system was ever used.

How did CarAndDriver and MotorTrend launch?

In those tests, prototypes had no launch control system so they employed what is called 'neutral dropping' technique, which essentially means pressing throttle to pre-determined launch revs while keeping it in neutral and abruptly shifting to first gear at launch time, which dumps it from neutral to 1st gear when launching.

This technique is highly flawed resulted in poor 0 - 60 mph times and was never intended to be a launch method since it results in too much wheelspin and since 1st gear is not pre-selected at launch time, the car needs to think first to shift from neutral to 1st causing lag while sudden shift shock results in bogging the car off the line when the tires 'bite' the road.

Hence the lower than factory claim 0 - 60 mph.

What did launch control do?

In Battle of the supercar, LFA employed launch control for the first time versus AWD Audi R8V10, which using r-tronic launch control consistently gets officially 0 - 60 mph in 3.4 - 3.5 seconds.

LFA's launch control proved to be highly effective resulting in no wheelspin off the line and also the car launched with 1st gear pre-selected resulting in instantaneous response.

As shown in this video where LFA launched 3 times against the AWD R8 V10 with both using launch control system and LFA hit 60 mph every time quicker than the R8 V10 and continued to pull away.

Now here is a screen capture of LFA from the R8V10's cabin at 66 mph. Both cars used launch control system in this run. Clearly, LFA is already 2.5 car lengths away by 62 mph (100 km/h) using launch control.

Since Audi always does 0 - 60 mph in 3.4 - 3.5 seconds with r-tronic launch control, suffice it to say LFA with launch control is easily 3.2 - 3.3 seconds, which not only clearly shows LFA not only meets the 0 - 60 mph in 3.6 seconds official claim, but surpasses it most likely by a few tenths.
