Battle of the Supercars did a head-to-head comparison of Audi R8 V10 with the Lexus LFA with Tanner Foust driving the LFA and Paul Tracy driving the R8 V10 at the runways of Westover Air Reserve Base.
LFA comprehensively was declared the winner by the presenter where LFA lapped the short 1-mile track 1 full second faster than the R8 V10 with a lap time of 48.9 for the LFA versus 49.9 R8 despite Tanner having difficulties launching the Lexus LFA in the 1-mile road course lap and also the standing mile drag race where LFA won despite a delayed launch (no launch control used for these runs).
This test also saw LFA using launch control for the first time in the 0-100-0 mph test, which led to the LFA accelerating from 0–161 km/h (0–100 mph) much faster than the R8 V10.
