# Mercedes-Benz CLS (C257)

The C257 Mercedes-Benz CLS is the third generation of the CLS range of four-door sedan, and was launched in 2018 as the successor to the Mercedes-Benz CLS (C218). It is only available as a sedan, with no plans to introduce a Shooting Brake variant in the near future. It is based heavily on the E-Class (W213).

## Development and launch

Information on the C257 CLS was released online on 29 November 2017, with a public unveiling at the Detroit Auto Show in January 2018.
The new CLS uses a four-link front suspension and a five-link rear suspension and comes in rear-wheel drive and all-wheel drive (4MATIC) configurations. CLS 53 4MATIC+ models utilise variable all-wheel drive, allowing for torque distribution between the front and rear axles. An electric motor is used to boost power output by 16 kW (21 hp) and 249 N⋅m (184 lb⋅ft), and also powers the on-board 48-volt system.
The CLS is also now a five-seater car, instead of being a four-seater as with the previous two generations.
