Video: Lexus IS-F vs Audi RS4

On the top left corner we have an all-new contender in the high-performance sedan category, the rear-wheel-drive 2009 Lexus IS-F packed with a 5.0-litre V8 engine pumping out 416 Hp. On the opposite side, we have an old friend who’s just one-step from retirement, the all-wheel-drive Audi RS4 with a 420 Hp 4.2-litre V8. Follow the jump to check out the full comparison test from the folks at Edmunds and see whether the IS-F has that something to throw the RS4 off its throne.
