The horsepower wizards over at RENNtech have focused their wrenches on the already potent Mercedes-Benz C63 AMG to create what they consider to be a fitting heir to the Mercedes 6.3, appropriate given the name and the fact that latest C-Class has grown nearly to the size of that legendary sedan. To achieve this proper Überness, they’ve released the 6.2 AMG V8 from the grips of unnecessary restriction and managed to squeeze out nearly 100 additional horsepower. The sleek sedan achieves up to 548 HP and 510 lb-ft of torque thanks to new engine management, long-tube headers and new pipes. To handle all of that extra power you might want to opt for the new RENNtech brake kit and, just to be safe, throw in the height control suspension system for some up and down goodness and you have yourself one mean machine. Full details in the release below the jump.

For most people, the abundant power and superb handling of the amazing Mercedes-Benz CLK63 AMG Black Series is more than sufficient. Straight from the factory, the CLK 63 Black boasts an output of 373 kW/507 hp and 630 Newton meters of torque - enough to propel the CLK from 0-62mph in just 4.3 seconds and reach its electronically-limited top speed of 186 mph easily. But there’s more than that! There’s the high-performance brake system, the track-optimized adjustable threaded suspension, the specially-developed cooling systems… the list goes on… But, for those of you whose always looking for more, the nice boys at Renntech have introduced a tuning package for the CLK 63 Black Series - one that extract a bit more power and drivability from an already supremely capable vehicle.
The magicians at Renntech have managed to increase power output of the CLK63 AMG Black Series to 550 horsepower, and even more impressive, they’ve also managed to deliver an additional 45-60 lb-ft of torque between 2400 and 5000 rpm. According to the founder of Renntech, Hartmut Feyhl: “Real-world performance is all about torque, not so much about a peak horsepower number at very high rpm. It can be very easy to build high rpm horsepower, but to get instant throttle response and mid-
range acceleration it is more difficult, and this is where customers really want to feel that improvement.”
But again, there’s more than just engine power to look at. Next, the CLK63 Black Series‘ handling was tweaked. Renntech has somehow lowered the car an extra 3/4″ and added carbon-fiber strut braces and fully-adjustable camber bushings at all 4 corners. But wait, there’s more! To improve aerodynamic efficiency, an adjustable carbon fiber rear wing and a front splitter/rear diffuser combination were added, and completing the package are some high performance brake pads and stainless-steel braided lines (ensuring an ample amount of stopping power, should the need arise).
While Renntech’s tuning package isn’t necessary to experience the thrill and exhilaration in your CLK63 AMG Black Series, it is a nice and simple way to experience more of what your dominating Mercedes already provides.
