The Mercedes-Benz C-Class (W206) is the fifth generation of the Mercedes-Benz C-Class which is produced by Mercedes-Benz Group AG (formerly known as Daimler AG) since 2021. It replaces the W205 C-Class which has been produced since 2014.^[4] 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.^[5]

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.^[5]

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.^[5] 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).^[5]

The C-Class All-Terrain was released as the crossover-styled estate model.^[6] Bearing the X206 codename, it received external body cladding, a 40 mm increase in ride height, 4Matic AWD and additional drive modes.

The smallest available petrol engine is the 1.5 liter M264 engine offered in the C 180 model (rated power 125 kW (168 hp; 170 PS)),^[7] and in the C 200 model (rated power 150 kW (201 hp; 204 PS)).^[7] The C 300 model is powered by a 2.0 liter 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.^[5]

Daimler initially offers two Diesel models, the C 220d, and the C 300d. Both models are powered by the same 1992 cm³ 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.^[8] 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 "4MATIC" all-wheel drive system will be offered as a factory option on both the C 300e and C 300de types. The plug-in hybrid models are supposed to have an all-electric range of 100 kilometres.^[9]

As of April 2022, AMG offers a new engine in the C 43 4MATIC: a turbocharged 2.0 liter 4-cylinder M139 engine + 48V electric motor, rated a combined 300 kW (402 hp; 408 PS).
