In 2018, 27% of new light-duty vehicles sold in the US had fuel economies of more than 30 miles per gallon (783 l/100 km), according to the US Department of Energy (DOE). By contrast, none of the light-duty vehicles produced in 1975 had fuel economy greater than 30 miles per gallon (mpg). In 2018, 2.4%

Manufacturers have been adopting technologies that improve the efficiency of light-duty vehicles and allow them to achieve greater fuel economy. Turbo charging and stop/start are two other engine technologies that reached a production share of about 30%, while cylinder deactivation (CD) was at 12%. Source: DOE, US EPA.

The all-new 2018 Volkswagen Tiguan arrives in US dealerships this summer powered by the most advanced version yet of Volkswagen’s EA888 four-cylinder engine, the Gen3B. Audi engineers described the development of the Gen3B at the Vienna Motor Symposium in 2015. The net effect is lower fuel consumption and more torque than the 2.0-liter

Researchers at ORNL, in partnership with FCA US and Nemak USA, have developed a new suite of aluminum-based alloys that could give automakers a boost in achieving ambitious fuel economy goals. Current alloys inhibit engine efficiency because they soften at the peak temperatures present in highly efficient advanced engines.
