Getting an early reveal ahead of Frankfurt, the 2017 Mercedes-AMG C63/C63 S Coupe clearly lives up to all the pre-launch hype. True to information M-B has spent the last month leaking along with disguised images of the prototypes being tested, the production Mercedes-AMG C63 and its hotter C63 S sibling will turn up in showrooms here next summer with over-the-top performance to match their aggressive style. 

As expected, the new C63 Coupe signals its enthusiast leanings through unique bodywork that shares only its doors, roof panel and decklid with the regular C-Class Coupe. Beyond standard LED lighting systems, both the C63 and C63 S feature the full AMG exterior treatment from a deeper splitter, oversize air intakes and wind-channeling elements up front to recast rear fascia that boast competition-inspired diffusers, twin dual exhaust outlets and a functional decklid spoiler. In addition to aero-optimized side sills, the fenders on these new AMG coupes also are roughly 2.5-inches wider to accommodate their upsized wheel/tire fitments and expanded track dimensions.

Motivating these performance coupes is a new AMG-spec M177 4.0-liter V8 Biturbo engine that develops 469-horsepower in the C63 and 503-horses in the C63 S. Both are attached to the cradle with adaptive Dynamic mounts and teamed with the latest AMG SpeedShift MCT 7-speed sport transmission, a paddle-shift cog changer that offers Controlled Efficiency/Sport/Sport+ modes plus a "Race" setting that's exclusive to the C63 S. Turning out 479 lb-ft of torque and 516 lb-ft of torque, respectively, the C63 Coupe hits 60 mph in 3.9 seconds and reaches an electronically limited speed of 155 mph and the C63 S a tenth of a second quicker to 60 on its way to a 180-mph top end.  

Although the C-Class basic structure carries over, it has been suitably reinforced for this AMG application to cope with the added stress from the extra engine and cornering power. The fully redesigned, sport-tuned suspension features AMG-specific components along with tri-mode AMG Ride Control adjustable dampers complemented by a mechanical limited-slip rear differential on the C63 and an electronically controlled unit on the C63 S.

Inside, the new C63 and C63S Coupes match the typical array of AMG-spec enthusiast-oriented elements with plenty of comfort/convenience touches from a Burmester Premium Sound System and Panorama Sunroof to a 7.0-inch center display and power heated front seats. Optional equipment largely parallels the other C-Class models and includes upgrades like Comand Navigation with Voice Control and a 360-degree camera with Parktronic along with the full assortment of active/passive safety systems.  

The 2017 Mercedes-AMG C63 and C63 S are set to take on rivals like the Audi RS5, BMW M4 and Cadillac ATS-V. While formal pricing won't be released until closer to the on-sale date, the C63 is expected to start "in the low-$70s" with the C63 S commanding roughly another $10,000.
