2018 Mercedes-Benz CLS - Technology from the S‑Class

The third generation of the CLS is powered by completely new engines, initially in-line six-cylinder diesel and petrol units. Also characteristic of the four-door coupé is the extensive range of 4MATIC models. 

The output of the diesel unit ranges from 210 kW (286 PS) and 600 Nm of torque in the CLS 350 d 4MATIC through to 250 kW (340 PS) and 700 Nm in the CLS 400 d 4MATIC. The special traits of the top-of-the-line engine in the diesel family include the stepped-bowl combustion process, two-stage turbocharging and, for the first time, the use of CAMTRONIC variable valve-lift control. 

Its design features a combination of an aluminium engine block and steel pistons as well as further improved NANOSLIDE® coating of the cylinder walls.

The new CLS generation has many things in common with the new S‑Class, the automotive flagship of the entire industry: the CLS is equipped with the latest generation of driving assistance systems, with route-based driver support provided by the Driving Assistance Package. 

Active Distance Control DISTRONIC and Active Steering Assist now provide even more comfortable support for the driver to keep a safe distance and steer. The speed is now adjusted automatically ahead of bends or junctions.


The most powerful engine is the six-cylinder petrol unit. The new, systematically electrified in-line six-cylinder with EQ Boost (integrated starter/generator) and a 48 volt onboard electrical system powers the CLS 450 4MATIC. Its performance data: 270 kW (367 PS) and 500 Nm plus a further 250 Nm of torque and 16 kW (22 PS) available via EQ Boost over short periods. 

The integrated electric motor known as EQ Boost assists the combustion engine e.g. when accelerating, makes driving without the combustion engine possible (“sailing”) and supplies the battery with power by means of high-efficiency recuperation. By doing so it makes fuel savings possible that were previously the exclusive domain of high-voltage hybrid technology. All in all, the new in-line six-cylinder engine delivers the performance of an eight-cylinder engine with significantly lower consumption. The CLS 450 4MATIC is equipped with a particulate filter as standard.
