Just because it's newer doesn't mean it's better.
Lexus had a great first attempt at a sports car, but alas, BMW has been in the game much longer and its advantage shows. As it appears, the debate has been settled. The Lexus RC-F simply loses to the BMW M4 in every way, shape, and form. Despite the fact that it has slightly more power, its weight prevents it from being the sports car that it has the potential to be. Even a fancy torque vectoring differential can't make up for the downsides that an overweight chassis deals out.
On the other hand, we had the opportunity to drive the RC-F and were pleasantly surprised at its ability to plaster a smile on our faces no less wide than what an M4 could manage.
The only problem is that in the automotive world, winning by a few tenths of a second is still winning, and the same goes for the substantial sales lead that the M4 has over the RC-F. The sales lead is partially due to BMW's continued dominance in the segment and in part because of brand loyalty, but as we find out here, not all of the BMW fanboys are right because the M4 doesn't win by a huge margin. The reason for this is the two turbochargers. When going against each other in a rolling race, all 5.0-liters of the Lexus engine are ready to go at the twitch of a right foot. Meanwhile, the BMW has to spool its goods up before it puts down the power. The results ultimately speak for themselves, but we still don't like the idea of delayed gratification.
