BMW has published new details about their next-generation Efficient Dynamics engine family. As you already know we are talking about three- and four-cylinder petrol and diesel units. According to the report, the changes have been made for better fuel consumption, noise levels and pollution levels. 

As you know, those engines can be mounted longitudinally or transversely and will be find on BMW and MINI models. The first model that might get the new generation engines will be the upcoming 2017 5 Series. 

The petrol engines will come with a boost of seven horsepower and 15 pound-feet of torque across each level of tune. As a result, the 1.5 liter unit will deliver 103 and 115 horsepower while the 2.0 liter will have a range of power between 149 and 234 horsepower. The fuel consumption will be improved by 5%.

The TwinPower turbo set-up will be found on every engine and it has high-pressure direct fuel injection, Valvetronic variable lift on the inlet valves, and Double VANOS variable valve timing. The cooling system was also modified.

On the diesel side, BMW promises a 5% bump in fuel economy and lower emissions. The German car manufacturer focused on emissions. This is why we will find a new exhaust gas recirculation (EGR) system will scrub more harmful nitrogen oxide from exhaust gases than before and an additional selective catalytic reduction (SCR) system.
