BMW has announced that it wants to expand its twin turbo powered technology to it’s smaller engines, including 4-cylinder and 3-cylinder power plants. The engineers say that the technology featuring a twin-scroll turbo charging coupled with direct-injection and variable valve management delivers a bigger output and efficiency from a smaller engine.
The technology debuted back in 2009 on the 3.0 liter inline six-cylinder gasoline unit fitted to the 5-Series GT. The technology is also used on other models and larger displacement power plants. BMW plans the upgrade on both diesel and petrol 3-cylinder and 4-cylinder units as being its highest volume engine groups.
