That's compared to the standard car's 457HP and 600Nm or 442 lbs-ft of torque. AVUS claims that along with the removal of the C63 AMG's speed limiter, the sedan can now reach a maximum speed of 320km/h or 199mph.
Other mechanical upgrades include 8piston brake calipers with 380mm diameter, a new set of springs and coilovers that lower the C63 AMG's ride height and a stainless steel exhaust system that promises to produce a more aggressive sound from the V8 engine.
Visually, as with the other proposals we've seen from AVUS Performance, you'll really need to take a close look at the car to spot the changes. These are limited to a new set of 19-inch multispoke AMG alloy wheels (20's are available as an option) and the black paint finish on the mirror covers, rooftop, front grille and the Mercedes-Benz star.
