Zoom-Zoom, indeed. Toyota may be the world's biggest maker of hybrids and Nissan may be making big strides on the plug-in front with increased sales of its Nissan Leaf electric vehicle, but it's Japanese automaker Mazda that has once again topped the Environmental Protection Agency's (EPA) list of most fuel-efficient automakers selling vehicles in the US, increasing its Model Year 2012 average by half a mile per gallon compared to MY2011.

Mazda wins with a 27.5 mpg average.

According to the EPA's "Trends" report (PDF), Mazda not only had the highest fleetwide fuel economy last year, but it also had the lowest emissions rate among the 11 largest automakers in the US. Mazda boosted its 2013 model-year fuel economy to 27.5 miles per gallon, up from 27 mpg. The company's fleetwide emissions fell to 324 grams of CO2 per mile, down from 328.

Honda came in second on the fuel-economy front with an even 27 mpg, while Volkswagen and Subaru tied for third at 26.2 mpg. Chrysler/Fiat filled out the bottom of the list with 21.6 mpg, just beaten by General Motors with 22 mpg. Chrysler/Fiat did have the largest year-over-year fuel economy jump at 1.5 mpg, however.

Mazda has eschewed hybrid and plug-in powertrains in favor of its more efficient Skyactiv engines and platform development technologies, and it also doesn't offer many large vehicles – its CX-9 crossover sells in modest numbers and it doesn't offer any pickups. After years of slow sales, Mazda finally appears to be on to a winning formula, announcing plans in August to Skyactiv engine production because of stronger-than-expected sales. Mazda expects to sell 1.7 million vehicles worldwide by 2016, and Skyactiv engines are expected to account for 80 percent of those sales. Mazda's official press release is available below.

MAZDA NAMED THE MOST FUEL-EFFICIENT AUTO MANUFACTURER IN U.S. ENVIRONMENTAL PROTECTION AGENCY REPORT

IRVINE, Calif., Dec. 16, 2013 /PRNewswire/ -- The U.S. Environmental Protection Agency (EPA) noted in their most recent Light Duty Fuel Economy Trends report that Mazda Motor Corporation is the most fuel-efficient auto manufacturer in the U.S. With the highest fleet-wide adjusted fuel economy performance of 27.1 miles per gallon (MPG), and the lowest CO2 emissions of 328, Mazda led the chart for model year (MY) 2012.

While still retaining the fun-to-drive characteristics for which Mazda is known, the company had the second largest increase (2.1 MPG) in the report over their MY 2011 MPG (25.0). Mazda has achieved the highest fuel efficiency of any other mainstream automotive manufacturer in the industry, without offering a hybrid or electric vehicle. Mazda's unique SKYACTIV®[1] TECHNOLOGY has made this level of efficiency possible. SKYACTIV is a suite of component and engineering technologies that incorporate 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 Jim O'Sullivan, president and CEO, Mazda North American Operations. "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 percent 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."

Mazda's SKYACTIV TECHNOLOGY brought the company to the forefront of fuel efficiency through such vehicles as the all-new 2014 Mazda3, the 2014 Mazda6, and the 2014 CX-5. Mazda3 reaches near best-in-class fuel economy with 41 highway MPG when equipped with the i-ELOOP energy regeneration system. Mazda6 equipped with i-ELOOP achieves class- leading fuel economy with 40 highway MPG. At 35 MPG, CX-5 still retains the title of the highest highway MPG of any SUV in North America, including hybrids.
