The paper looks at changes in Sweden’s new car fleet between 2002 and 2010. Between 2002 and 2007 consumer amenities such as acceleration capacity and passenger space con- tinued to increase while fuel consumption steadily decreased. During these years the main technological and market change was a shift toward diesel and flex-fuel ethanol vehicles. After 2007 the average weight and power of the vehicles were more or less constant, while fuel consumption decreased by 13% between 2007 and 2010. The developments after 2007 suggest that 77% of the technological development between 2002 and 2010 resulted in reductions in fuel consumption compares to previous years when 35% of any technology change resulted in a net reductions. The shift can partly be attributed to the increased share of diesels and an engine downsizing.

Nyckelord: Specific fuel consumption, Downsizing, Service attributes, Performance attributes, Diesel cars, Flex-fuel cars
