In July of last year, the average fuel economy index for new vehicles in the U.S. market was 24.8 mpg (approximately 9.48 liters per 100 kilometers).
The University of Michigan Transportation Research Institute began tracking U.S. new vehicle fuel consumption on a monthly and yearly basis starting in October 2007. The calculation result for that month was 20.1 mpg (approximately 11.7 liters per 100 kilometers), and to date, the average fuel economy of new vehicles in the U.S. has improved by 27%.
