Let us pit two rear-drive luxury coupes - the 2015 BMW M4 and the 2015 Lexus RC-F - against each other in a battle for tire-smoking glory.
Also, we find out which one is faster and more fun to drive by visiting the instrumented test track, the winding road course at Hyundai’s Proving Ground, and Streets of Willow racetrack with pro driver Randy Pobst.

Comparing the RC F with the M4 on track.
And now for an entertaining drag race between our two contenders.
