It's been a long time coming, but the all-new, redesigned C63 is finally here. Available in two power variants and, for now, two body styles, the car will now be addressed according to the company's new nomenclature: Mercedes-AMG C63 for the base model, and C63 S for the upgraded version. Both feature the Mercedes-AMG GT's 4.0-liter twin-turbo V8 engine, known as the M177 in these new models. The entry-level C63 produces 469 horsepower and 479 lb-ft of torque, while the S model delivers 503 hp and 516 lb-ft of torque.

Meanwhile, the S model delivers 503 hp and 516 lb-ft of torque. In its sedan configuration, the 2015 AMG C63 S weighs in at 1,655 kg, 15 kg less than the outgoing model. With an electronically-limited top speed of 250 kph (155 mph), the C63 makes the 0-62 mph sprint in 4.1 seconds (sedan) and 4.2 in the estate/wagon. The C63 S will reach the same speed in 4 seconds (sedan) and 4.1 (estate). All variants are mated to AMG's seven-speed Speedshift MCT automatic with paddle shifters and four driving modes – controlled efficiency, sport, sport plus and race (only available in the C63 S). With no 4Matic available for now, these monsters will be fully rear-wheel-drive.

They will also feature a revised suspension with new springs and dampers, reworked bushings and a ride height that underpins the regular C-class by 25mm. The C63 will feature a mechanical locking differential, while the S gains the electric locking differential sourced from the AMG GT S. Carbon ceramic brakes and a performance exhaust will also keep things up to standard. Official pricing and an on sale date will be announced later.
