Porsche’s understated supercar doesn’t look that different, but she’s got it where it counts. It’s wider, has staggered wheels, 10-piston carbon ceramic brakes, enhanced aero, and can go 0-to-62 in 2.7 sec, thanks to its massively-upgraded 641 bhp, 3.8L twin-turbo flat-6. With AWD and rear-wheel steering it’s precise too.
