2017 Mercedes-AMG C63 Coupe Brings Twin-Turbo Punch with Up to 503 HP

Two doors, huge power.

As you might have deduced from the numerous teasers, there's a new go-fast Mercedes-AMG coupe on the way. The 2017 Mercedes-AMG C63 Coupe, which makes its public debut next month at the Frankfurt auto show, expands the C-Class Coupe lineup with a twin-turbo punch.

Following in the footsteps of the C63 sedan, the 2017 Mercedes-AMG C63 is offered in two trim levels, both of which use a 4.0-liter twin-turbo V-8 engine, a 7-speed automatic transmission, and rear-wheel drive. The standard C63 boasts 469 hp, 479 lb-ft of torque, a claimed 3.9-second 0-to-60-mph time, and an electronically limited top speed of 155 mph. Moving up to the C63 S bumps those figures to 503 hp, 516 lb-ft, 3.8 seconds, and 180 mph.

Don't think that AMG simply took the standard 2017 Mercedes-Benz C300 Coupe and dropped in a larger engine. In fact, the only body panels the AMG C63 shares with the standard C-Class Coupe are the doors, roof, and trunk. Compared to the C300, the C63 has flared fenders that are 2.5 inches wider in front and 2.6 inches wider in rear. It also wears an AMG-specific body kit, with enormous intakes gulping air through the front fascia, aerodynamic "flics" and a splitter to keep the nose pinned to the ground at speed, a prominent rear diffuser, a quartet of parallelogram-shaped exhaust tips, and a contrasting black trunklid spoiler.

Racier Handling

AMG also made sure the 2017 Mercedes-AMG C63 Coupe can tackle corners as well as it can dispense with straights. The car's track has been widened an inch and its wheel alignment given more negative camber, and by flaring the fenders, AMG can fit up to 255 section-width front and 285 rear tires. Both dynamic engine mounts and the AMG Ride Control adaptive suspension damping come standard. On the regular C63, a mechanical limited-slip differential distributes power to the rear wheels, while the C63 S has an electrically controlled limited-slip.

Key rivals for the AMG C63 Coupe include the Audi RS5, the BMW M4, the Cadillac ATS-V coupe, and the Lexus RC F. In terms of raw power, AMG's effort trumps the all: The RS5 packs 450 hp, the M4 has 425 hp, the ATS-V has 464 hp, and the Lexus RC F comes in with 467 hp. But we'll have to get these high-power sports coupes together before we can fully establish how they stack up.

After a public debut at the Frankfurt auto show on September 15, the 2017 Mercedes-AMG C63 Coupe will reach U.S. dealers in summer 2016. Pricing will start in the low-$70,000 range for the standard car, and in the low-$80,000 range for the C63 S.
