At the New York Motor Show BMW released the first real-world details of its new, more fuel efficient, four cylinder future by plonking a 2.0 litre turbo into the BMW Z4. The classic roadster look, with the long bonnet, but powered by a piddly four cylinder?
Fear not doubters, because the curiously named Z4 sDrive28i has 176kW (240hp) at its disposal and is sure to shift quite nicely. It also features “TwinPower Turbo technology”. Terminology equally designed to trick the mind, as the twin refers to high precision injection and a single twin-scroll turbocharger; not twin turbos.
Oh, remember that rumour of the road-going MINI Countryman WRC we told you about? Well, don’t be surprised if this engine, or one closely related to it, with perhaps more power, finds it way under the bonnet.
BMW Z4 at the New York Motor Show (April 20/21) with new 2-litre TwinPowerTurbo engine for the first time.
19.04.11 Munich. With its athletic design, agile handling and powerful engine, the BMW Z4 has achieved outstanding success in the class of premium roadsters, having been the worldwide segment leader in 2009 and 2010. Towards the end of the year, the BMW Z4 is to feature another technological highlight: a completely newly developed 2-litre engine with TwinPower Turbo technology and an output of 176 kW/240 bhp. Its name is BMW Z4sDrive28i.
Thanks to TwinPower Turbo technology, the new supercharged 4-cylinder petrol engine with all-aluminium crankcase, already available in the BMW X1 xDrive28i, provides increased torque, improved performance and much reduced fuel consumption and emission levels as compared to the existing 6-cylinder induction engine model BMW Z4 sDrive30. The absolute figures, including those for the driving performance of the new BMW Roadster, are expected to be finalised mid-year.
This newly developed engine in the BMW Z4 sDrive 28i uses the globally unique BMW TwinPower Turbo technology. In other words it is fitted with High Precision Injection as well as a turbocharger powered via two exhaust ducts. Other elements of this progressive engine package include the variable camshaft control system double VANOS and the fully variable valve control system VALVETRONIC.
The new 2-litre petrol engine with BMW TwinPower Turbo technology in the BMW Z4 sDrive28i thus sets a further milestone in the BMW EfficientDynamics strategy.
