variant but with fuel economy of a strong hybrid. HyBoost achieves this by combining aggressive 50% downsizing of the engine with an electric supercharger for transient low-speed performance, and a micro-hybrid stop-start and energy recuperation systems, Boggs said.

The ICCT notes that while diesels generally consume less fuel than comparable gasoline vehicles, CO 2 emissions from diesel engines are not lower in the same proportion, for various reasons. On top of the higher energy density of diesel fuel, diesel engines historically possessed a number of efficiency advantages over gasoline engines.

A report published by Cambridge Econometrics and Ricardo-AEA concludes that overall, the cost of technologies required to meet proposed European 2020 CO 2 regulations for vehicles (95 g/km for cars and 147 g/km for vans) will be more than offset by the resultant fuel savings. The project is taking a phased approach.
