Porsche

Porsche's 3.8-litre direct injection flat-six engine from the Porsche 911 Carrera S won best new engine, seeing off competition from the ubiquitous BMW 3.0-litre diesel unit from '30' monikered cars and Jaguar's impressive new supercharged 5.0-litre V8 found in the XKR and XFR. The panel of judges chose Porsche's lump for its combination of fuel economy and response, as well as its significant decrease in CO2 output compared to the 3.6-litre engine it replaced.
