Mercedes-AMG’s model onslaught continues with the release of the CLS53, as does its diversification into new powertrain solutions.

Debuting at the Detroit Motor Show, the CLS53 returns to Mercedes’ roots by using an inline six-cylinder engine, while also casting one eye to the future thanks to its mild hybrid system.

The 3.0-litre turbocharged inline-six produces 320kW/520Nm of its own accord, however, the ‘EQ Boost’ electric motor, fitted between the engine and transmission, adds an extra 16kW/250Nm, operates as a starter-alternator, generates power for the 48-volt electrical system and allows the use of an electric compressor to effectively eradicate turbo lag.

Visually, the CLS53 can be identified by the twin-blade grille in silver chrome, which also adorns the front splitter and fins in the outer air intakes, while at the rear there are twin tailpipes and a boot spoiler.
