AMG CLS 63

Segment
Sedan

The Mercedes-Benz CLS63 AMG is already an incredible factory-produced car. But what happens when a renowned German tuning firm gets their hands on one with the sole intention of giving it even more power? German tuner MKB has just released full details about its modified CLS63 AMG equipped with the optional Performance Package. Based on the existing model before the recently announced update, standard power comes from a 5.5-liter bi-turbo V8 that produces 557 horsepower and 590 lb-ft of torque.

However, MKB went ahead and did its naughty thing by increasing output to 700 hp and 737 lb-ft thanks to some adjustment work on the car's ECU along with some additional mods such as a new high-flow exhaust system. All told, the sleek four-door coupe will go from 0-62 mph in a blazing 4.1 seconds, down from 4.3. Its original top speed was electronically-limited to 155 mph, but MKB upped it to 186 mph although that's been limited as well. However, those opting to remove the limiter altogether will see a top speed hovering at around 211 mph. The tuning kit is on sale now and comes with a full warranty.
