Last October, we released a report: "Factor of 2: Halving the Fuel Consumption of New U.S. Automobiles by 2035". The piece got some attention from Joe White at the Wall Street Journal just a month before the U.S. Energy Bill increased fuel economy standards for the first time in 20 years.

The report details design and sales mix changes that could halve fuel consumption (measured in liters of fuel consumed per 100 kilometers) in the average new vehicle sold in 2035. This translates into a fuel economy of roughly 50 mpg by 2035--a target that is nearly as ambitious as the 35 mpg by 2020 requirement in the Energy Bill.

The report is available on our research group's website. Check it!
