While the average for all European manufacturers is currently about 160g/km of CO2, Audi's average is 179g/km. The original proposal would have required all companies to meet a 130g/km limit. The Audi A1 coming in 2009 is expected to drop Audi's average by 5g/km. At the same time Audi has been bringing out increasingly powerful models like the R8 sports car and the upcoming Q7 V12 TDI. Unlike the US based automakers, the Germans can't even call for higher fuel taxes since Europe already has high fuel taxes. If a sliding scale based on weight is enacted it definitely needs to drive significant reductions even for heavier cars even they don't come down to the 130g/km level.
