2014 Mazda3 2.0L Hatchback officially rated at 40 mpg highway

The Environmental Protection Agency has spoken, and these are the miles per gallon numbers it has officially bestowed on the 2014 five-door Mazda3 hatchback with the SkyActiv-G 2.0-liter engine: 29 city, 40 highway, 33 combined when fitted with the six-speed manual; 30 city, 40 highway and 33 combined when equipped with the six-speed automatic.
Those numbers exactly match the fuel economy targets that Mazda had set for the car when optioned with the 2.0-liter Skyactiv-G with 155 horsepower and 150 pound-feet of torque. For comparison to other cars in the segment, the EPA numbers for the 2013 Honda Civic sedan are 28 city, 39 highway, 32 combined when its 140-hp, 1.8-liter four-cylinder is paired with the five-speed automatic. The Hyundai Elantra GT gets 27 city, 37 highway and 30 combined according to the EPA when its 148-hp, 1.8-liter four-cylinder is paired with either a six-speed manual or six-speed automatic transmission. The numbers for the 2014 Ford Focus aren't out yet.

Mazda returns to rotary with RX-Vision Concept, crowd goes wild

Rotary! Forget everything for a second. Ignore the sleek styling, formed-by-wind sheetmetal, outrageously rear-drive proportions, and general ridiculousness of the sideview mirrors. And please be so kind as to ignore the poorly lit photos here – Mazda has a thing for drama. Concentrate instead on one fantastic phrase from the concept car press release: "next-generation Skyactiv-R rotary engine." The crowd here in Tokyo was downright frothing to get a look at the new concept car – hoping to catch a glimpse of the first evolutionary stage for a RX-9 sports car. The critical factor in that effort is of course the rotary engine. Mazda says that, while production of the powerplant is "on hold," the company has "never stopped research and development towards the rotary engine." The fact that the company has named the new engine gives us great hope that it exists in reality, and will be available for sale at some future date. The devil is in the details though, and there are precious few available at the Mazda stand. Other than a brief history lesson about Mazda's racing heritage, and fuzzy-vision talk about the future, we only have expectations to feed on. Oh, there's also a tiny press release, below. Related Video: HIROSHIMA, Japan—Mazda Motor Corporation unveiled the rotary-powered Mazda RX-VISION sports car concept at the Tokyo Motor Show*1 today. The rotary engine is a symbol of the company's "never-stop-challenging" spirit. RX-VISION represents a vision of the future that Mazda hopes to one day make into reality; a front-engine, rear-wheel drive sports car with exquisite, KODO design-based proportions only Mazda could envision, and powered by the next-generation SKYACTIV-R rotary engine. Rotary engines feature a unique construction, generating power through the rotational motion of a triangular rotor. Overcoming numerous technical difficulties, Mazda succeeded in commercializing the rotary engine, fitting it in the Cosmo Sport (known as Mazda 110S overseas) in 1967. As the only automaker to mass-produce the rotary engine, Mazda continued efforts to improve power output, fuel economy and durability, and in 1991 took overall victory at 24 Hours of Le Mans with a rotary engine-powered race car. Over the years, the rotary engine has come to symbolize Mazda's creativity and tireless endeavor in the face of difficult challenges. While mass production is currently on hold, Mazda has never stopped research and development efforts towards the rotary engine.

Toyota, Honda, Nissan and more collaborating to increase fuel efficiency

Toyota, Honda, Mazda, Nissan, Subaru, Mitsubishi, Suzuki and Daihatsu have announced an alliance that will see a push to improve fuel economy from both gas-powered and diesel-powered engines by as much as 30 percent before the end of the decade.
The newly assembled Research Association of Automotive Internal Combustion Engines put the roughly $20-million project together, with the Japanese government committing to half the cost while the eight manufacturers will chip in the rest.
According to Automotive News, the automakers will team up and share basic research on internal-combustion engines in a bid to cut costs. Eventually, the results of the research will find its way into a production vehicle, although it's unclear just when we'll see the fruits of this partnership on the road.
