Edo Competition’s tagline for their tuned Mercedes-Benz C63 sedan is fairly accurate. After finding that the stock 457 horsepower 6.3-liter V8 engine wasn’t enough, they set off to make an even more impressive beast.
For this car, edo decided to keep the C63 looking the same as stock. No typical tuner body kit or wild colors on this one. The only visual modification are the wheels, which are lightweight 19-inchers designed specifically for the car, and are for function over form.
The biggest changes are in the form of performance modifications. Edo has taken the 6.3-liter V8 stock engine and added a new high-performance exhaust system, high-flow headers and catalytic converters, new air filters, and a tuned ECU. The remote controlled butterfly valve exhaust system helps keep torque high at low revs without restricting power higher in the RPM band.
These changes boost the 457 hp and 442 ft-lbs of torque to 555 hp and 501 ft-lbs. A most significant upgrade that allows the new edo C63 to reach 62 mph from a stop in 4.3 seconds, and reach a top speed of 199 mph.
The edo competition Mercedes Benz C63 is what you could call a sleeper, in a way. It’s already a high performance car, but these enhancements will help it leave other C63s in the dust while still appearing as a from-the-factory car, minus the “edo competition” decals on the sides.
