Mercedes-Benz developing new range of eco-engines

Mercedes and Renault are working together to create a range of four-cylinder petrol engines with the aim of matching the fuel efficiency of the new BMW three-cylinder unit.
It is so confident that the 1.2-litre petrol and 1.5-litre diesel four-cylinders will achieve this that no Mercedes three-cylinder petrol will be developed.
With EU tailpipe emissions targeting 95g/km by 2020, the new four-cylinder engines will play an important role in Mercs plans for the future. Along with the mainstay of the Renault range, the new A- and B-Class models will get the new engines from 2014.
However, Mercedes are still vowing to continue making large luxury cars despite the increasing demand to reduce CO2 emissions. It plans on doing this by developing plug-in hybrid drivetrains for future Mercedes cars. Tougher design targets for core components will also help weight reduction.
Mercedes also believe that its current Bluetec diesel technology can easily be adjusted to prepare its engines for the EU7 NOx emissions regulations due in 2020.
