Understated but not underpowered
The 2018 Mercedes-AMG C63 S packs a 503-horsepower punch from its beefy V8 biturbo engine and has been re-tuned to deliver 503 horsepower and 516 pound-feet of torque from the same power plant.
That juice flows to the rear wheels through a 7-speed multiclutch automatic transmission (MCT). This gearbox operates mostly like a conventional automatic transmission but uses a wet startup clutch instead of a torque converter for improved performance and efficiency.
The driver controls the attitude of the C63 S and its AMG heart with a Dynamic Select wheel on the center console which toggles between Comfort, Sport, Sport+ and Race modes. Each setting adjusts the performance of the throttle response, transmission programming, suspension damper firmness, and traction control.
The C Class chassis also makes for a very comfortable daily driver; just pop its Dynamic Select switch into the Comfort mode and feel the AMG Ride Control suspension settle into its softest setting, the optional AMG Performance exhaust quiet down, and the 7-speed automatic transmission relax. The V8 biturbo engine, which can be quite ferocious at speed, still feels effortlessly athletic on the interstate.
It's powerful and composed under pressure, but also comfortable and relaxing on a commute. The exterior design is probably the most understated in its class.
