Mercedes-Benz has announced the latest edition of its M3 challenger – the new C63 AMG. The new uber-C has an AMG hand-built 6.3L V-8 with 451 hp and 443 lb-ft of twisting force. As with other Germans from Audi and BMW, the C63 has it’s terminal velocity electronically capped at 155 mph, although the acceleration is capped only by physics with 60mph available in 4.5 seconds.
All that twisting force is transferred from the crankshaft to the drive-shaft via AMG’s Speedshift Plus 7G-TRONIC transmission, which can be manually manipulated by paddles on the back side of the steering wheel. The programming on this application adds the ability for the engine to automatically open up the throttle during downshifts to match revs and smooth things out. The electronic stability control also now provides the driver the ability to select the activation thresholds for the system to activate. More details from Stuttgart after the jump.
