The already stunning CLK 63 AMG Black Series didn’t leave much room for improvement. However, Kleemann’s engineers didn’t hesitate for a second, when they received this challenge in 2008. Fitted with a Kleemann 63-K2 kit, the engine power output was increased to 545 HP and 675 Nm (497 lb-ft) of torque ensuring a top speed of more than 320 km/h (199 mph) and acceleration from 0-100 km/h (0-62 mph) in just 4 seconds.

The Kleemann philosophy of “Comfort Power” represents the idea that tuning isn’t just about raw power and radical styling. The main goal must always be power and drivability in perfect harmony. The Kleemann CLK 63K AMG Black Series K2 was a perfect example of just that.
