Expect more to come in the way of twin-scroll turbocharging from BMW – the company is set to expand its application of TwinPower Turbo tech to cover its four- and three-cylinder engine jobs.

First seen in 2009 in a six-cylinder 3.0 litre petrol unit on the 5-Series GT, the package – which has twin-scroll turbocharging, direct gasoline injection and fully-variable Valvetronic valve management as part of the game – made its way on to a four-cylinder unit, the 2.0 litre petrol block in the X1 xDrive28i introduced in Geneva.

It’s all part of the plan by the company to offer more horsepower while cutting back on CO2 levels. The 245 hp output from the 2.0 block is significantly higher than the 156 hp offered by the normally-aspirated version.

According to a report, the company hasn’t disclosed just when TwinPower Turbo will be made available on a new family of three-cylinder engines it’s looking at to power the next-generation Mini and upcoming entry models in its BMW model lineup. It has however stated that the three-cylinder unit is expected to be the dominant engine plug in its lineup by 2015.
