The launch of BMW’s new 2.0-liter 4-cylinder TwinPower engine was only the first in the new family of engines for the German automaker. Most of the engines available today in the BMW lineup will be redesigned so that they can share more parts.
The new engines are designed to be more efficient and follow the EfficientDynamics Strategy that BMW has in places. The engines will utilize a new common 500cc per cylinder base design, which also used Direct-Injection and Turbocharging and will range from 3 to 6-cylinder capacity.
Fuel intake and exhaust system will share components based on the fuel type and mounting and powertrains will also be standardized. Harland Unger, head of development for BMW inline engines stated, “Our goal is to have 60 percent of components hared between engines based on fuel type, and 40 percent commonality between gasoline and diesel engines.”
Future Twin-Power Turbo diesel engines will share fuel injectors, turbochargers, pistons, connecting rods, chain camshaft drives and noise-suppression covers. Additionally, Twin-Power Turbo engines will be used in hybrid powertrains. These applications explain the need for a 1.5-liter three-cylinder engine rumored to be available in the 2014 BMW i8.
