The new generation of turbocharged engines are still producing very decent power outputs, but their main concern is to improve fuel-economy, and a company that is getting the most out of this type of set-up is BMW.
They have thus-far developed twin-turbo V8’s, twin-turbo and twin-scroll (called TwinPower) turbo straight sixes, and TwinPower four-cylinder engines. Now BMW are planning on even smaller turbo engines. According to the latest reports from Bavaria, BMW is developing turbo-charged three-cylinder engines, which will go into upcoming small BMW and Mini models.
These new engines, which are part of BMW’s long-term goal to cut emissions by an additional 25% will start appearing in production vehicles by 2014.
