Like its name suggests, the fellas at Heat 2 Head like to put some of the coolest cars on the road against one another to see who comes out the victor. In the latest episode, the guys put two German heavyweights against each other: the the 2014 BMW M5 Competition and the 2014 Mercedes-Benz E63 AMG S Model. Jonny Lieberman and Mike Shaffer have the pleasure of putting these two muscular machines against each other, and they do a rather fine job of dissecting each car's good and bad features.

The M5 and the E63 AMG deliver a combined 1,152 horsepower and 1,092 pound-feet of torque: 575 horsepower from the M5 and 577 horsepower from the E63 AMG. On paper, it looks like the two sedans->ke142 are identical, but which of the two perform better with your derriere in the driver's seat?

The guys first took the two sedans to the dyno gurus at K&N engineering to validate the to-the-wheel numbers. With these numbers in hand and some rough -- and flawed -- estimations on what the car's put out at the crankshaft, the two were ready to hit the track.

Check out the video to see which of the two sedans comes out on top.
