Do you need a little bit more oomph for your Mercedes-Benz C63 AMG Coupe? Vath promises to address your needs with its new Väth V63 tuning kit that brings a host of engine, chassis, exterior and interior upgrades.

But before you read on, you might want to know that the package - not including the car itself - is priced at €64,308 or about US$83,600.

If for some very strange reason you find that the Mercedes-Benz CLS 63 AMG lacks some serious punch under its hood, Germany's Vath has developed a new performance package for Stuttgart's sports saloon.

The tuner breaths more fire into the CLS 63 AMG through the use of its V63RS engine kit that bumps the 5.5-liter bi-turbocharged V8's output from 525-hp and 700-Nm to 660-horses and a whopping 990Nm or 730 lb-ft of peak torque.

There are plenty of reasons to leave the latest Mercedes-Benz CL 63 AMG untouched, but some folks out there are always open to improvements. Enter the world of German tuning firm Väth that has unleashed a new performance package for the Mercedes' facelifted coupe.

Väth starts with the V63S tuning kit that includes a software upgrade for the ECU bumping the bi-turbocharged V8's output from 536HP 590 lb-ft to a monstrous 630-horsepower and 686lb-ft (930Nm) of peak torque.
