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.

Hey guys, might want to change the title. Two errors here, twin-scroll does not mean twin-turbo, and it’s 3 cylinder engines, not 3 liter engines. ;-)
This article is wrong somehow.
I don’t get the news.
@Damien – the article is correct, where it mentions ‘3 litre’ it’s regarding the 3.0 litre, 6 cylinder engine fitted in the 5-Series GT.
Ah, so they will transplant the technology from the 6-cylinder 3.0l engine to the 3 and 4-cylinder engines of 1- and 3-series.
That’s right, and the 3 and 4 cylinder engines will have similar power and efficiency to the bigger engines, therefore making it possible for a 4 cylinder 1-Series to perform like a 6 cylinder 3-Series (theoretically at least)
