It's no surprise that we love the R8, but this just takes the kuchen and proceeds to sprinkle it with a magical topping named Bruce. MTM's R8R vs. ABT's R8. In a tunnel. Epic win.

They're both similarly tuned, so how does MTM's 560 HP, supercharged R8R stand up to ABT's 530-horsepower, supercharged R8 offering? You'll soon find out, though they're both winners in our book and we'd be hard pressed to choose one over the other. [via gtspirit]
