New 2011 BMW 5-Series(F10) was unveiled back in November. Even though it is not yet available at your local BMW dealership, there are tuners offering upgrades for the all-new 5er.
German tuner Racing Dynamics is previewing their tuning program for the new 5-Series, including both visual and performance upgrades.
Their top of the range model will be called R50S and is based on the new 550i that gets a power boost from 407 hp to an impressive 620 hp from the twin-turbo V8. Racing Dynamics will also add a new new rear-locking differential, sport suspension and high performance braking system.
The new 535i gets a power increase from 306 hp to 410 hp and is called R35. 0 to 62 mph is reportedly 5.3 seconds, seven tenths faster than the the regular model.
Both the R50S and R35, also get a special exhaust system with a much sportier sound. We expect Racing Dynamics to reveal more details in the near future. We are just as curious as you to see the performance numbers for the 620 horsepower R50S.
