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.
