Both versions get a choice of wood and aluminum interior accents. Interior, Comfort, and Cargoīlack faux-leather/microfiber upholstery is standard in the regular-strength C63, while the S models have leather seats. The coupe and cabriolet are both EPA-rated at 17 mpg in the city, but the coupe has a 26-mpg highway rating versus 24 for the convertible. The sedan is rated at 18 mpg city and 27 mpg highway ratings. There's no difference in EPA fuel economy between the C63 and C63 S, but there are differences among the body styles.

2019 Mercedes-AMG C63 Tested: A Mighty Muscular C.

This capability comes at the price of comfort, as the ride is harsh over rough pavement. Equipped with summer tires, the C63 S managed 1.02 g's of lateral acceleration on our skidpad and braked from 70 mph to a stop in just 157 feet.

Dynamic engine mounts are included on C63 S variants. All C63s come standard with an electronically controlled limited-slip rear differential and an AMG Ride Control suspension with adaptive dampers. In Lightning Lap 2019, a C63 S coupe turned in a 2:57.1 lap, which puts it right behind the discontinued Cadillac CTS-Von our all-time list. In our testing, the C63 S went from zero to 60 mph in 3.7 seconds and ripped through the quarter-mile in 11.9 seconds at 122 mph we haven't tested a C63. Top speed is electronically limited to 155 mph on the regular C63 and 180 mph on the S. Both engines use a nine-speed automatic with rear-wheel drive. The C63 S ups the performance ante with 503 horsepower and 516 lb-ft. In the C63, it makes 469 horsepower and 479 lb-ft of torque. The 2020 Mercedes-AMG C63 and C63 S have a hand-built, twin-turbo 4.0-liter V-8 engine. Instead, we'd get the standard C63 sedan and add the Exterior Lighting package to get adaptive LED headlights and the AMG Performance front seats, because they are exceptionally supportive. Only the S has the nine-step AMG Traction Control system, but we found it too intrusive in the C63 coupe that we drove in Lightning Lap 2019, so it's not a must-have. It's hard not to want the more potent C63 S model, but the actual performance differences are slight. Plus, we like the understated appeal of a fast four-door. It's lighter than the coupe, which has a full-length panoramic sunroof that lets in sunlight but packs on pounds. While you might prefer the style of the coupe or convertible, our money would go to the sedan. The price of the 2020 Mercedes-AMG C63 starts at $69,095 and goes up to $85,895 depending on the trim and options. Iridium Silver Metallic is a new exterior color. All 2020 C63 convertibles come with the Aircap feature, which uses deflectors to keep the open-air cockpit warm or cool, and power-folding sideview mirrors.

Sedans and coupes now have keyless access and hands-free trunklid control as standard. There are a few equipment changes on the 2020 Mercedes-AMG C63. We could do without the harsh ride, but the C63 is so much fun you might not care. Either way, this car gathers speed in gobs and promises to bring excitement to your humdrum commute. The regular C63 makes 469 horsepower, while the C63 S is tuned to make 503 hp. It's available as a sedan, coupe, or convertible, and every one of them comes with a twin-turbocharged V-8 engine hand-built by engineers in Affalterbach, Germany. So we should all be happy for the existence of the 2020 Mercedes-AMG C63, the hot-rod version of the Mercedes-Benz C-class. It's getting harder to find a car in the compact-luxury class with ridiculous levels of performance.
