Mercedes-Benz has pulled the wraps off its all-new CLS-Class in Los Angeles, revealing a fresh design that houses an all-new inline six-cylinder engine.

The CLS 450’s new motor is a 3.0-litre with an integrated starter generator that turns the car into a light hybrid. Dubbed EQ Boost, the system runs on a 48-volt electrical system and can add a burst of up to 22 hp and 184 lb-ft of torque to the gas-fueled engine’s 362 hp and 369 lb-ft.

In normal driving, the electric motor backs up the gasser when possible and can move the car on volts alone in a so-called “sailing” mode. Naturally, the system also incorporates regenerative braking.


Mercedes-Benz claims the new engine provides the “performance of an eight-cylinder engine with significantly lower fuel consumption.” It also promises reduced exhaust emissions levels thanks to a particulate filter.

Standard features include LED headlights, Apple CarPlay/Android Auto smartphone integration with wireless charging, 19-inch wheels, a 12.3-inch infotainment display, and 64-colour ambient interior lighting with illuminated air vents.

An optional widescreen cockpit puts two 12.3-inch screens side-by-side beneath a single glass cover.

A new Energizing setup uses lighting, climate control, fragrance, and musical atmospheres “to create a specific wellness setup that is tailored to the mood and needs of the customer.” There are six modes to choose from, too, called freshness, warmth, vitality, joy, comfort and training.


Despite the CLS-Class’s upscale position, active safety is optional as part of the driving assistance package. It brings improvements to Mercedes’ active steering and lane change assist systems and includes the pre-safe impulse side function, which uses the seat bolsters to shove occupants away from an impending side-impact collision.

The radar cruise system now also allows the car to remain stopped in traffic for up to 30 seconds before it begins moving again in response to traffic conditions.

Other options include an air suspension with what Mercedes calls an improved adjustable and adaptive damping system.

The new Mercedes-Benz CLS-Class will reach the brand’s Canadian dealerships in summer 2018.
