Just days after Mercedes unveiled facelifted versions of the C-Class Coupe and Cabriolet, bosses have revealed tweaked C 63 models – boasting AMG’s latest nine-speed automatic gearbox. Power is unaffected, with standard and ’S’ variants available across the C-Class range. 

The C 63 saloon, Estate, Coupe and Cabriolet have all been confirmed, mirroring many of the changes made to the standard range earlier in the year. Both boast the same 4.0-litre bi-turbo V8, with either 469bhp (C 63) or 503bhp (C 63 S). Top speed for the saloon and Coupe with S power is limited to 180mph. The limiters on the Estate and Cabriolet are set at 174mph, while all standard C 63 cars are muzzled at 155mph.

AMG boss Tobias Moers said: “The AMG C-Class is our best-selling model series and therefore a key cornerstone of our company’s success of recent years. The perfected driving dynamics and expressive design underscore the powerful, muscular character of the rear-wheel drive icon.” 

Visual tweaks include a new AMG-specific radiator grille, special aero wheels and gloss chrome exhaust pipes. In addition, buyers can also spec an optional AMG Aerodynamics package for the C 63 Coupe, which adds a more aggressive front splitter, spoiler lip and border side skirts. Inside, you’ll find fully digital dials and an updated AMG steering wheel, while buyers are now offered open-pore wood trim, as well as extra carbon trinkets. 

Under the skin, AMG engineers have extensively re-tuned the suspension and dampers, as well as the electronically controlled limited-slip differential. The diff is now standard on all 63 models, while S versions also boast dynamic engine mounts. The new nine-speed dual clutch gearbox is lifted from the larger E 63, offering shorter shift times than before. 

Six drive modes are available: Slippery, Comfort, Sport, Sport+, Race and Individual, with the last of these allowing owners to tweak their car’s settings to suit their driving style. Within these modes there are four ‘agility functions’: Basic, Advanced, Pro and Master, which are automatically selected by the respective drive program.

Despite the various tweaks, performance is unaffected. That means the C 63 S saloon can accelerate from 0-62mph in 4.0 seconds, while the Estate is one-tenth slower. The Coupe is faster still (3.9 seconds), while the Cabriolet completes the same sprint in 4.1 seconds. Non-S versions are slightly slower across the board. 

Prices for the updated AMG C 63 will be announced later in the year, with UK deliveries expected in the summer.
