The BMW M5 is a massive and heavy car, so it's a good thing it's got carbon ceramic brakes. Otherwise, well, let's just say the laws of physics won't work in its (meaning the driver's) favor. But the lure of its 4.4-liter twin scroll V8 producing 592 hp and 516 lb-ft of torque is way too tempting to not give it a go. All told it'll hit 62 mph from a standstill in only 3.9 seconds and has an (electronically controlled) top speed of 155 mph. And then there's its two-door little brother, the M4.

Lighter, more modern, it churns out 425 hp and 406 lb-ft from its twin-turbo inline-six. 0-62 mph happens in 4.3 seconds and top speed, once again, is 155 mph. But which of these two mighty M cars is better on track? It's a hard and tireless job, but the guys over at Evo managed to pull through as they pitted the two cars against one another.
