New 2022 Mercedes-AMG C 43 unveiled with 402bhp

 The new-generation Mercedes-AMG C 43 is here, and it will go on sale in the UK in May. Available as a saloon or an estate, the new C 43 features a totally new engine layout supported by mild-hybrid technology and fresh chassis equipment taken from newer AMG models in the Mercedes line-up. It arrives ahead of the next C 63 which, it has been confirmed, will move to plug-in hybrid power. 

The new M139 engine pinched from the A 45 S hot hatch means the C 43 gets a bump in power over its 375bhp V6-powered predecessor. The new car produces 402bhp at 6750rpm and 500Nm of torque at 5000rpm. This extra power comes courtesy of a 2.0-litre four-cylinder turbocharged set-up with 48-volt mild hybrid-assistance, as found in the new SL 43 roadster. 

The 48v system can briefly provide an additional boost of 14bhp through the belt-driven starter generator. Power is sent through a nine-speed automatic transmission with a wet start-off clutch, replacing the old torque converter. 

The new C 43 is based on an updated version of the MRA platform of the previous generation C-Class. But just like mild-hybrid rivals - the BMW’s M440i and the Audi S4 - the new Mercedes-AMG C 43 now offers permanent four-wheel drive. The brand’s 4MATIC four-wheel drive system offers a rear-biased configuration with up to 69 per cent of the power going to the rear wheels. Rear-wheel steering is standard on the C 43, enabling a tighter turning circle. 

Beating both rivals from BMW and Audi, the new C 43 accelerates from 0-62mph in 4.6 seconds. There’s an electronically limited top speed of 155mph but Mercedes offers an optional AMG Driver’s Package which raises the top speed to 165mph. 

Despite not being the full-fat C 63, the brakes have also been upscaled to cope with the extra power. The C 43 gets ventilated six-piston calipers at the front with 370mm brake discs. 

As you’d expect of an AMG-badged Mercedes, the drive mode selection programme is expansive. There are five ‘AMG Dynamic Select’ programs - Slippery, Comfort, Sport, Sport+ and Individual. The Sport and Sport+ programs increase the engine's responsiveness, quicken the transmission's shifting behaviour and the suspension and steering are tuned to be more agile.

Adaptive dampers are standard. These continuously adapt the damper profile to suit the driving style and condition of the road surface. Mercedes offers three different damping settings within its ‘AMG Ride Control’ system - Comfort, Sport and Sport+.
