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.

Forza Horizon G-Shock Car Pack brings Nissan IDx, Subaru Brat [w/video]

With winter's icy grip around much of the nation, now may be the perfect time to sit inside at night and enjoy some video games. The latest six-car G-Shock pack for Forza Horizon 2 on the Xbox One is now here, and it gives players a very eclectic group of vehicles to race around the game's open world. This month's group of vehicles spans the decades ranging from 2015 back to 1953. The newest and only concept of the group is the 2015 Nissan IDX Nismo. Since the production chances for this retro coupe look increasingly slim, this game might be your only chance to get behind the concept's wheel. However, if you prefer driving something a bit more classic and Italian, the 1953 Ferrari 500 Mondial is available. To add one more flavor of performance, there is the 2010 Mazda Mazdasped 3 hot hatch, which is also this month's free car for download. In addition to three takes on the sports car, Turn 10 is also offering a trio of off-roaders. The quirkiest among them is the 1980 Subaru Brat GL, which features two jump seats in the back to avoid the dreaded chicken tax. If you prefer something more boxy and American, then the 1975 Ford Bronco is sure to please. Finally, for some real power to get through the mud, there's the 2013 Ford F-150 SVT Raptor as tuned by Shelby with a supercharged 6.2-liter V8 making 575 horsepower. As usual, the whole pack costs players $5 to download, or it's free as part of the season pass. Scroll down for a brief video showing all of these virtual rides off and read the press release about them from Turn 10 Studios. This content is hosted by a third party.

Tougher than steel: Wood pulp could make lighter auto parts

KYOTO, Japan — The global push among carmakers to make ever lighter vehicles is leading some auto suppliers in Japan to turn to what seems like an unlikely steel substitute — wood pulp. Japanese researchers and auto component makers say a material made from wood pulp weighs just one-fifth of steel and can be five times stronger. The material - cellulose nanofibers — could become a viable alternative to steel in the decades ahead, they say, although it faces competition from carbon-based materials, and remains a long way from being commercially viable.> Related: Jay Leno drives the Renew cannabis car — hemp you can't dent Reducing the weight of a vehicle will be critical as manufacturers move to bring electric cars into the mainstream. Batteries are an expensive but vital component, so a reduction in car weight will mean fewer batteries will be needed to power the vehicle, saving on costs. "Lightweighting is a constant issue for us," said Masanori Matsushiro, a project manager overseeing body design at Toyota. "But we also have to resolve the issue of high manufacturing costs before we see an increased use of new, lighter-weight materials in mass-volume cars."A NEW PROCESS Researchers at Kyoto University and major parts suppliers such as Denso Corp, Toyota's biggest supplier, and DaikyoNishikawa Corp, are working with plastics incorporated with cellulose nanofibers — made by breaking down wood pulp fibers into several hundredths of a micron (one thousandth of a millimeter). Cellulose nanofibers have been used in a variety of products ranging from ink to transparent displays, but their potential use in cars has been enabled by the "Kyoto Process," under which chemically treated wood fibers are kneaded into plastics while simultaneously being broken down into nanofibers, slashing the cost of production to roughly one-fifth that of other processes. "This is the lowest-cost, highest-performance application for cellulose nanofibers, and that's why we're focusing on its use in auto and aircraft parts," Kyoto University Professor Hiroaki Yano, who is leading the research, told Reuters in an interview. The university, along with auto parts suppliers, are currently developing a prototype car using cellulose nanofiber-based parts to be completed in 2020.
