We’ve already covered the 2011 Cadillac CTS-V against the new 2012 M5, but what about BMW’s Stuttgart rival?

Since the E28 BMW M5 first came on the scene in 1988, BMW has absolutely owned the factory super sedan market. That is, until Mercedes-Benz decided to get serious; in 1997, Mercedes-Benz, now owning their tuning brand, AMG, outright, they decided to produce a limited run E50 AMG to compete in Europe against the BMW M5. It wasn’t a bad start, but it was when they brought us here in the states the E55 AMG in 1998 that things got serious.

These days, though, Mercedes takes their fight against BMW’s M5 very seriously. They’re definitely the most bitter and closely matched rivals, especially with the new M157 twin-turbo 5.5-liter V8 in the 2012 E63 AMG, that’s a pretty tough competitor to the 2012 BMW M5 sporting a twin-scroll turbocharged 4.4-liter V8. Let’s have some specs and pictures, shall we?

That’s enough of the number games, now it’s time for the real comparison: the pictures.

The rest of the pictures of the E63 AMG are of the 2010-11 model. Mercedes-Benz has only added a few 2012 MY pictures to their press site, not enough to compare the design to the M5’s. Don’t worry, the 2010-11 are identical inside and out, though.

So which car would you rather spend your money on, the E63 AMG or the M5? As much of a Bimmer guy I am, I would never complain having the AMG, even though I’d rather have the M5 for its manual transmission.

Why don’t you head on over to the RawAutos Forum where we can finish this discussion/debate, huh?
