The standard Mercedes-Benz C63 AMG sedan with its 457HP 6.2-liter naturally aspirated V8 lump is by no means a slow car, but when it comes to the tuning industry, the more ponies under the hood, the merrier. Bypassing the colorful body wrap, which is optional anyway, German tuning firm Wimmer RS starts by upgrading the C63 AMG’s eight-cylinder engine.
The massaging includes a sports camshaft, reworked cylinder heads, a new manifold and down pipe, high flow catalytic converters and a reconfigured ECU that help nudge output from 457HP and 600Nm to 601HP and 720Nm (531 lb-ft) of peak torque. Wimmer RS also removes the electronic speed limiter allowing the modified C63 AMG to reach a maximum velocity of 329 km/h (204.6 mph). The engine conversion by Wimmer RS costs €19,900 or about US$26,700.
