Meet the new Mercedes-Benz C63 AMG. The competitor to the F80 BMW M3 launches with two power variants coming from a 4.0 liter V8 bi-turbocharged engine that delivers 470 hp and 650Nm (479 lb-ft) in the base model, and 503 hp and 700Nm (516 lb-ft) in the C63 S AMG.

Power is sent to the rear wheels via a seven-speed AMG Speedshift automatic transmission.
From 0 to 100 km/h (62 mph), it only takes 4.1 seconds for the C63 S AMG and 4.2 seconds for the base model. Both cars are limited to 250 km/h (155 mph).
The F80 BMW M3 features the same S55 3.0 liter inline-six TwinPower engine producing 425 horsepower and 406 lb-ft of torque. The power is sent to the rear-wheels via a six-speed or an optional 7-speed M DCT transmission.
For comparison, with the seven-speed DCT, the M3 and M4 need 4.1 seconds from 0 to 100 km/h, switching to manual speed, the two cars need 4.3 seconds. However, with increasing speed, the advantage of the stronger AMG is likely to be getting bigger.
According to Mercedes, the C63 S AMG has a minimal consumption of 8.2 liters while the new M3 and M4 consume, based on the transmission selected, 8.3 to 8.8 liters.
Until the two competitors are put on a track, here is a photo comparison showcasing the sporty design from both German automakers:
