The Mercedes-AMG S63 E Performance is the most powerful S-Class yet, with 791bhp and 1055lb ft of power and torque. However, this increased power comes with the downside of adding 309kg to the car’s weight, bringing it to a total of 2520kg.

Equipped with AMG’s nine-speed automatic gearbox and four-wheel drive system, the S63 E Performance can go from 0 to 62mph in just 3.3 seconds.

Although its performance numbers are impressive, the question remains: can this larger and heavier S63 deliver the same level of engagement and dynamics as its highly rated predecessor?

The S63 E Performance offers seven different driving modes: Electric, Comfort, Battery Hold, Sport, Sport+, Slippery, and Individual. This provides the car with incredible versatility for various driving conditions. In everyday driving, the Comfort mode utilizes both petrol and electric power sources to offer a refined and urgent experience on the motorway, giving the impression that there’s always more power to spare.

Switching to Sport+ mode unleashes the true sledgehammer performance of the S63 E Performance, with the electric motor’s torque compensating for any lag as the turbos spool up. This results in acceleration similar to that of a supercar, thanks to the 4Matic+ system and electronically controlled limited-slip differential that provide outstanding traction and determination when applying full throttle. However, due to the combination of two separate gearboxes and the 4Matic+ system, there can be some unruly shunt, particularly at low speeds and when accelerating quickly.
