These numbers are achievable in Europe using current small diesel and petrol engine technology. Even by 2020 when the E.U will demand an average closer to 100 g/km -- that's 55 miles per U.S. gallon -- small capacity 3- and 4-cylinder boosted direct injection gasoline engines with stop/start systems and a plethora of other innovations will still be in the majority.
Will American drivers migrate towards smaller fuel efficient vehicles that cost less to meet the new fuel and emission standards or are we willing to pay more for hybrid vehicles?
Hybrid or not!
