Detroit Motor Show: 2018 Mercedes-AMG CLS53 revealed

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.

Combine this grunt with a nine-speed automatic and all-wheel drive and the result is a seriously quick car, the 1905kg CLS53 motivated to 100km/h in just 4.5sec on its way to an electronically-limited top speed of 250km/h. Efficiency also benefits, Mercedes claiming fuel use of just 8.4L/100km on the combined cycle.

The chassis is more traditional Mercedes fare: multi-link suspension front and rear with air springs and three-mode adaptive dampers, while braking is taken care of by 370mm discs and four-piston calipers at the front supported by 360mm discs and single-piston calipers at the rear.

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.

Inside, twin widescreen displays dominate the dash with virtually every other surface covered with leather, aluminium or carbon and detailing the vast array of safety and driver assist systems could fill an encyclopaedia.

Local pricing and specification will be revealed closer to the CLS53’s launch in the second half of 2018, but we’d expect it to split the existing E43 and E63 models at around $185K.
