Here's a neat animation of BMW's new Twinpower Turbo 4-cylinder Motor (aka N20) -
Full Tech Specs.
This new engine is a 2.0L gas powered 4-Cylinder engine which uses BMWs TwinPower (single turbo - twinscroll) turbo technology, good for 245HP and 350Nm of torque. This engine is closely modelled after its 6-cylinder brethern N54 and uses an all-aluminium crankcase, precision direct fuel injection, with VALVETRONIC.
The N20 engine will make its US debut in two models later this year. There's no official word yet, but we wouldn't be surprised if it was the X1 and the Z4 28i.
The N20 engine is now powering the X1 28i in Europe and the first reviews of this motor have been positive (
preliminary N20 reviews).
