Current average fuel economy levels vary consid- erably by country. Across the OECD the average figure in 2005 was around 8 litres per 100 km for new cars (including SUVs and minivans and in- cluding both gasoline and diesel vehicles). With a 50% fuel economy improvement, the average new car performance in OECD markets would improve to around 4 litres per 100 km (about 90 g/km of CO2). In the United States, fuel consumption is consid- erably higher than the OECD average: doubling of tested fuel economy would mean moving from the current new car (and light truck) average of 26 mpg to.
