BMW TwinPower for triples

2011-03-24 10:30

DOWNSIZING: BMW's engines are shrinking in the carmaker's bid to be more frugal, but turbo technology should appease the fans.

BMW is set to roll out its TwinPower Turbo technology, shown recently at the Geneva auto show, for its three and four-cylinder petrol and diesel engines.

The move is seen as another way for BMW to reduce its carbon emissions by 2020. As it stands, after a 30% reduction since 1995, the automaker quotes average carbon emissions for its European fleet as 156g/km with an average fuel consumption of 5.9 litres/100km - and those figures will improve considerably as its TwinPower Turbo package becomes more readily available.

TwinPower Turbo, which combines twin-scroll turbocharging, direct injection and the Valvetronic fully variable valve management system, has already been seen on BMW's straight sixes and V8 engines but the system's application in a four-cylinder, two-litre petrol engine on the X1 was demonstrated for the first time at the 2011 Geneva show.

The technology is also expected to be implemented on the manufacturer’s new range of three-cylinder engines, Automotive News reports, although BMW has not yet announced when this will take place.

The new three-cylinder engine will reportedly power the next Mini range and other entry-level models within the BMW line-up. Apparently this unit is expected to power most of BMW’s cars - up to 1.5 million a year - by 2015.
