The biggest upgrade for the M5 is that power allegedly increases to 592 horsepower (600PS) and 516 pound-feet of torque (700 Newton-meters). That is a 32-hp and 14-lb-ft increase over the standard M5 and 17 ponies more than models with the Competition Package. The forum claims that all of the cars come with a dual-clutch gearbox, even in the US.
Styling also sees an upgrade with BMW Individual Frozen Dark Silver Metallic exterior paint, special 20-inch wheels, dark chrome trim and 30th Anniversary badges. The interior mixes Merino leather and Alcantara upholstery with dark aluminum trim and more celebratory badges.
It seems BMW wants to keep this special edition a rarity because one photo suggests it's limited to 300 units. Bimmerpost believes its debut will be at the M Festival at the Nürburgring from June 20-22. That fits well with the alleged July production start date. Autoblog reached out to BMW USA for official confirmation of the car, but it had no comment at this time.
