2014 Mazda3 officially rated at 30/41 mpg, priced from $16,945*

It's hard not to be smitten with the 2014 Mazda3; after all, just look at it. But beyond its slick lines, we found the new compact hatch to be a pretty remarkable steer, offering up good levels of comfort and refinement, not to mention functionality and engagement. Now, there's more reason to like the 2014 Mazda3, as we've just learned that the car will officially be rated at 30 miles per gallon city and 41 mpg highway.
That 30/41 rating is for the Mazda3 sedan fitted with the 2.0-liter Skyactiv-G inline four-cylinder engine and a six-speed automatic transmission. Opting for the manual transmission retains the 41-mpg highway number, but drops the city digits to 29. Hatchback models with the 2.0-liter engine achieve 29/40 mpg with the manual 'box and 30/40 with the automatic.
Mazda also offers a larger 2.5-liter inline-four in the 3, and while a six-speed automatic will be the only transmission available with this engine at launch, the automaker has confirmed that a manual is coming shortly. With the 6AT and 2.5, the Mazda3 sedan is rated at 28/39 mpg, or 29/40 with the company's i-Eloop regenerative braking system. Hatchback models shrink those numbers to 28/37 and 29/39 mpg, with and without i-Eloop, respectively.

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.

LA Design Challenge invokes biology for 2025 concepts [w/poll]

Participants in the annual LA Design Challenge always manage to come up with edgy, wacky designs for future vehicles, but with a theme of "Biomimicry and Mobility: 2025" this year's crop of cars might be the quirkiest we've ever seen. As usual, automotive designers from around the world participated in this year's competition, and all the designs will all be unveiled next week during the LA Auto Show with a winner being announced on November 21.
Chinese automakers made a strong showing with Qoros, SAIC Motor, JAC Motors (the company responsible for the Ford F-150 clone) and Changfeng all bringing interesting takes on the biology, human intelligence and sustainability theme. One of the more innovative ideas among these automakers is the Qoros Silk Road System allows autonomous vehicles to drive in packs similar to how ants travel. Speaking of ants, the SAIC Motor Mobiliant (shown above) gets its design from the shape of an ant's body, and, like the insect, it can climb building acting as a personal elevator as well. The JAC Motors design also merges vehicle and building design, while the Changfeng LaBrea inspired by the design of muscle fibers.
Other entrants include Subaru and US-based design teams for BMW, Toyota and Mazda. BMW's duo of concepts mimic plant and animal life. The LA Subways concept acts as a submersible, single-person vehicle to take advantage of the LA river, with a shape similar to an Ocean Sunfish. The Sustainable Efficient Exploratory Device (SEED) imitates the shape of a seed pod, and uses propulsion methods inspired by a shark, dragonfly and a water bug. Mazda's Auto Adapt might be the most car-like concept of the bunch, while the Subaru Suba-Roo and the Calty-designed, Toyota e-grus are the most mind-blowingly awesome.
