Mercedes and Renault-Nissan preparing 1.2 and 1.4 petrol engines to meet future emission regs and increase fuel efficiency
The partnership between Mercedes and Renault-Nissan group is about to grow to a new level in the upcoming years as the global manufacturers tied up to collaborate for a new line two small displacement four-cylinder petrol engines. They displace 1.2 and 1.4 litres respectively and will have the direction injection fuel channeling philosophy. The next generation entry-level A and B class models will get benefitted by the new power units.
We have showed you the test prototypes of the upcoming new generation A-Class before and next year we would see it being unveiled. Alongside the high sales recording model, the other members of the same family including the CLA and Shooting Brake, A-Class sedan and even the GLA, GLB and B-Class may get strapped with one or both of the new lower displacing downsized engines.

In short, the majority of the eight base compact models in Mercedes-Benz range will see the introduction of the new small engines. Internally codenamed as the M282, they are developed for transverse applications and thus won’t be presented for the higher models. Additionally, the 1.2L and 1.4L engines will be joined by the upgraded version of the current M274. It will have the name M260 with 1,600 cc and 2,000 cc considered as the displacements.
Currently, the 45 designated models are powered by the M133 which is good enough to produce 381 hp and 475 Nm torque. It will give way to an updated 2.0L and is confirmed to develop in excess of 400 horsepower. If you consider the 2.0L units to be small for the bigger models, the technology and engine outputs will more than compensate for the displacements.

In recent years, the downsizing trend has grown enormously but the automakers believe that it would be difficult to meet emission regulations below 1.2L capacity on petrol mills from the future perspective. Renault-Nissan said at the Paris Motor Show last year that the limit of its downsizing capabilities has been reached. We may not ever see the 1.5 dCi getting a smaller sibling as well in the alliance’s model range.
