German aftermarket wizard, MKB, believes in the concept of "no frills" modifications. That’s why when it decided to upgrade its existing program for the Mercedes CLS 63 AMG, it did so by throwing this caveat: "Being MKB and being a German technology tuner MKB omits any optical gimmicks.”

That’s right; it’s calling aesthetic upgrades “gimmicks,” because for MKB, it’s all about what’s lying under the hood of that luxury sports sedan and we tend to agree.

When it comes to engine modifications, MKB takes its craft very seriously; seriously enough that the previous program that netted the CLS 63 AMG a total of 640 horsepower (up from the standard 550 ponies) doesn’t cut it anymore.

So MKB’s engineers went back to the lab and carefully readjusted the car’s ECU and tossed in some additional carefully tuned mechanic parts, including high-flow exhaust systems and tuned boost pressure.

This kit will boost your German Sports Sedan up to a total of 700 horsepower to go with an astounding 737 pound-feet of torque. Whatever language you speak, it’s hard not to come to the same conclusion that those are ill numbers.

As a result, of the added horsepower and torque numbers, you CLS 63 AMG will sprint to 100 km/h (62 mph) in just 4.1 seconds, 0.2 seconds faster than the version fitted with the optional AMG Performance Package. The top speed, which previously peaked at only 155 mph, will be bumped to an electronically-limited 186 mph. If you’re really extreme and choose to take out the limiter altogether, your luxury sports saloon can spank even those Italian super cars to the tune of 211 mph.

Here’s the best part: the conversion to MKB’s P700 program is already available, and comes with a full MKB warranty. In Germany, the tuner is even offering the conversion even with TÜV and emission class Euro 5.
