BMW TwinPower Turbo technology in the new four-cylinder engine

This new engine is the most powerful in a new generation of four-cylinder petrol units based on the same reduced-friction core engine, their different output ratings being achieved principally by modifications to the injection and turbocharging technology. In technical terms, this core engine is modelled on the current multi-award-winning six-in-line engine with BMW TwinPower Turbo technology, which is the benchmark in its class for dynamic power delivery and impressive efficiency. Key features of this world-exclusive technology include High Precision Direct Petrol Injection, twin-scroll turbocharging, Double-Vanos variable camshaft timing and VALVETRONIC variable valve timing.

These features give the new BMW 328i the sort of power which with a naturally aspirated engine would require more cylinders and larger displacement. At the same time, with its all-aluminium crankcase, this engine is lighter and more compact than a six-cylinder engine of equivalent power. This has obvious benefits for driving dynamics: the reduced load on the front axle gives this BMW sports sedan greater agility and further improved steering and cornering characteristics.
