MKB Gives CLS 63 AMG A Terminal Velocity Of 211mph

MKB works their tuning magic to give AMG’s 5.5 liter twin turbocharged V8 an additional 140 horsepower. That brings the CLS 63 AMG an output of 700 horsepower.  Torque output gets a similar hefty increase, from 590 lb-ft to almost 740 lb-ft.  With these kinds of figures, it’s not surprising that the four-door coupe sprints to 62 mph in 4.1 seconds: not a bad time for a heavy car like the CLS. Makes you wonder though how much punishment the drivetrain can take.

Theoretically, MKB’s CLS can go all the way to 210 mph, or 340 km/h. Since speeds like that require special tires and other considerations, MKB moves the speed limiter from the standard 155 mph to 186 mph. Realistically, there are only a few places left to reach those kinds of velocities any way. It would give the MKB-tuned CLS 63 owner a lot of satisfaction though to see jaws drop when they see what kind of rapid transport said CLS owner has at his disposal.
