As part of a concerted downsizing initiative, Mercedes-Benz will be introducing a brand new entry-level petrol engine in international markets – consisting of both, 1.2- and 1.4-litre direct-injection units.

The new four-cylinder engines, codenamed M282, are planned for launch in the next generation of compact Mercedes-Benz models, starting with the next-generation A-class which would go on sale internationally during the second quarter of 2018.

Following their introduction in the new A-class, the engines will be launched in upcoming successor models of the CLA, GLA, and B-class. They will also be used in the new A-class sedan, which was previewed by the Concept A saloon at the 2017 Shanghai motor show, and a new BMW X1-rivalling SUV model expected to be called the GLB. 

Developed in partnership with Renault-Nissan, Mercedes' parent company Daimler’s alliance partner,  the new engines have been conceived specifically for transverse applications. This means they are unlikely to be used in larger Mercedes-Benz models, even in hybrid applications.

The new 1.2- and 1.4-litre four-cylinder powerplants will join the line-up which features a heavily updated version of the existing M274 engine that will also be introduced in the new A-class. Named the M260, it will be offered in both 1.6-litre and 2.0-litre guises, with the latter forming the basis for a 406hp-plus successor to the AMG-developed M133 unit used by the A 45, CLA 45 and GLA 45 4Matic.
