The brains behind the common-rail injection system that shook up diesel technology have now produced a new technology designed to make petrol engines more efficient and cleaner. Engineers claim the MultiAir engines – which use electrohydraulic actuation, rather than the more widely available electromechanical systems – boost power and torque, while cutting CO2 by between 10% and 25% and other pollutants by up to 60%.

It seems almost certain if you watch this video – especially at around 3:15 where you can hear the turbos quite clearly – that forced induction is the route BMW are taking. But it seems likely that the M5 will get a few more horses than others in the BMW range using the same powerplant.
