Development and launch

Information on the C257 CLS was released online on 29 November 2017,^[12] with a public unveiling at the Detroit Auto Show in January 2018.^[13]

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.^[14] CLS 53 4MATIC+ models utilise variable all-wheel drive, allowing for torque distribution between the front and rear axles.^[15] An electric motor is used to boost power output by 16 kW (21 hp) and 249 N⋅m (184 lb⋅ft),^[16] and also powers the on-board 48-volt system.^[17]

The CLS is also now a five-seater car, instead of being a four-seater as with the previous two generations.^[18]
