Mazda has been named by the United States' Environmental Protection Agency as the most fuel-efficient car manufacturer in the country "with the highest fleet-wide adjusted fuel economy performance of 27.1mpg (11.5km/L)" for the 2012 model year.
The other carmakers that made it to the EPA's list are:
* Honda (26.6mpg or 11.3km/L);
* Toyota (25.6mpg or 10.9km/L);
* Volkswagen (25.8mpg or 11.0km/L);
* Subaru (25.2mpg or 10.7km/L);
* Nissan (24.1mpg or 10.2km/L);
* BMW (23.7mpg or 10.1km/L);
* Ford (23.7mpg or 10.1km/L);
* General Motors (21.7mpg or 9.2km/L);
* Daimler (21.1mpg or 9.0km/L); and
* Chrysler/Fiat (20.1mpg or 8.5km/L)
For the 2013 model year, Mazda is poised to retain the honor as the EPA's preliminary figures for the year shows a fuel economy of 27.5mpg (11.7km/L).
According to the EPA, Mazda achieved the highest fuel efficiency of any other mainstream automotive manufacturer in the industry without having a hybrid or electric vehicle in its lineup. What supposedly made this possible is the Japanese carmaker's suite of Skyactiv technologies that incorporates ultra-high compression-ratio gasoline engines, super-efficient manual and automatic transmissions, lightweight chassis and body components, reduced rolling resistance, and low-drag body styling.
"Mazda has long had a history of doing things differently, and Skyactiv technology is no exception," said Mazda North American operations president and CEO Jim O'Sullivan. "While other manufacturers have turned their attention to hybrids and electric cars, we chose to focus on perfecting the base technology used in more than 90% of the cars and SUVs sold today: the internal-combustion engine. Through analyzing and refining this technology, as well as every other component in a modern automobile, Mazda has been able to achieve class-leading fuel economy in nearly every segment it competes in, and bring that technology--at an affordable price--to every customer."
