# Mercedes-Benz C-Class (W206)

The Mercedes-Benz C-Class (W206) is the fifth generation of the Mercedes-Benz C-Class which is produced by Mercedes-Benz Group AG since 2021. It replaces the W205 C-Class which had been produced since 2014. The fifth-generation C-Class is available in sedan (W206), station wagon/estate (S206), and long-wheelbase sedan (V206) body styles. The W206 C-Class is based on the Mercedes MRA II rear-wheel drive modular platform also used by the W223 S-Class.

## Design

All W206 C-Class models are equipped with four-cylinder engines that have an integrated starter generator (15 kW electric motor) and a 48-volt electrical system. Daimler does not offer the W206 with halogen headlamps.
The W206 has independent front and rear suspension. The front axle is a four-link axle, the rear axle is a multi-link axle. Rear axle steering with a steering angle of 2.5 degrees is available as a factory option; the turning circle is reduced by 0.4 m to 10.6 m with the rear axle steering option. The interior styling is related to the S-Class (W223). The C-Class also has a central LCD display with a screen diagonal of either 9 in (230 mm) or 11.9 in (300 mm).
The C-Class All-Terrain was released as the crossover-styled estate model. Bearing the X206 codename, it received external body cladding, a 40 mm increase in ride height, 4Matic AWD and additional drive modes.

## Powertrain

The smallest available petrol engine is the 1.5-litre M264 engine offered in the C 180 model (rated power 125 kW (168 hp; 170 PS)), and in the C 200 model (rated power 150 kW (201 hp; 204 PS)). The C 300 model is powered by a 2.0-litre M254 petrol engine rated 190 kW (255 hp; 258 PS). The M254 is equipped with a twin-scroll "segmented" turbocharger featuring an overboost function that allows it to produce an additional 26 kW for up to 30 seconds, as well as a 48V electric supercharger that provides assist at low engine speeds.
Daimler initially offers two Diesel models, the C 220d, and the C 300d. Both models are powered by the same 1992 cm$^3$ OM654 engine, rated 147 kW (197 hp; 200 PS) in the C 220d, and 195 kW (261 hp; 265 PS) in the C 300d. Compared with the preceding Diesel engine, the OM654 has a new crankshaft that increases the stroke to 94.3 millimeters, and a water-cooled, variable turbine geometry turbocharger. In July 2021, the C 200d was introduced with a detuned version of the above engine, now producing 120 kW (163 PS; 161 bhp) of power and 380 N⋅m (280 lb⋅ft) of torque.
Daimler has announced that it will be offering a plug-in hybrid model with a petrol engine, the C 300e, as well as a plug-in hybrid model with a diesel engine, the C 300de. The mainline C-class 4Matic models and AMG C43 continue to use permanent AWD with an open double-planetary type center differential. The two axles are linked by a pre-loaded two plate clutch with a locking action of 50nM. Two versions of Magna's Trumax open center differential transfer case are used. The non-AMG models use the version geared for a 45/55 front-to-rear torque split. AMG C43 models are offered with the more rear-biased AMG-Performance Permanent AWD, which uses a center differential geared for a 31/69 front-to-rear torque split. The AMG C63 uses the AMG-Performance 4Matic+ AWD. This system replaces the open center differential with an electronically controlled multi-disc clutch which enables stepless coupling of the front axle to the drivetrain. The rear axle is permanently driven. Drive torque distribution to the front axle is infinitely variable throughout the range of between 0 and 50% of total gearbox output torque. The plug-in hybrid models are supposed to have an all-electric range of 100 kilometres.
As of April 2022, AMG offers a new engine in the C 43 4MATIC: a turbocharged 2.0-litre 4-cylinder M139 engine + 48V electric motor, rated at a combined 320 kW (429 hp; 435 PS).
The M139 4-cylinder engine in the C 63 S E-Performance produces 350 kW (469 hp), giving it a specific output of 235 hp (175 kW) per litre or 117 hp (87.5 kW) per cylinder, making it the current most powerful four-cylinder engine in serial production.
