When it debuted in the mid-1980s, the E28 BMW M5 was known as the fastest production sedan in the world. The current F10 M5 is certainly no slouch either, and for its 30th birthday, it will get a power bump to nearly 600 horses.
The folks at Bimmerpost have some leaked details on the 30th Anniversary Edition M5, and it sounds like some proper German rocket sedan hotness. They say the car's twin-turbo 4.4-liter V8 will get bumped from 560 horsepower up to 592, and torque gets a mild boost up to 516 pound-feet.
It's a far cry from the first M5, which debuted at the Amsterdam Motor Show in 1984 and had 282 horsepower in Euro-spec trim from its race-derived 3.5-liter inline six.
Other goodies include the Competition Package, 20-inch jet black wheels, frozen dark silver metallic paint, leather and Alcantara all over the damn place, and a 30th anniversary badge.
A sad note for manual purists, though: this special M5 will reportedly only come with the dual-clutch transmission. That's kind of a bummer, but the DCT is pretty excellent.
Check out Bimmerpost for more pics and info. I wish I could say they're doing a limited new run of 300 E28 M5s to celebrate the occasion as well, but this sounds pretty good on its own.
