Mazda going back to oval grille with next MX-5 Miata

The original Mazda MX-5 Miata was distinguished by an oval grille - a design trait that gradually evolved into the smiling cat face on the latest model. But Mazda, according to the latest intel, is planning on returning to that oval grille with the new model in the works.
The revised grille will cap a slightly longer form than models past, while still keeping weight down to a minimum. The stretched wheelbase was reportedly adopted in order to meet the requirements of Alfa Romeo, which is jointly developing the new platform together with Mazda for use on a new roadster of its own.
The new Miata is expected to adopt the 1.5-liter Skyactiv four found in the Mazda3, albeit returned to rev higher and deliver more power and torque, mated to either a six-speed manual or automatic. The Alfa version, meanwhile, is expected to use a 1.4-liter turbo four with a dual-clutch transmission. Sources anticipate the new MX-5 to debut first, possibly at the 2015 Chicago Auto Show a little less than a year from now.

Mazda6 Skyactiv-D racecar gets first win at Road Atlanta

Mazda has a long motorsports history, and one that is peppered with fascinating cars. The latest chapter in Mazda's racing story has just been written, as Joel Miller and Andrew Carbonell have driven the Visit Florida Racing Mazda6 Skyactiv-D to the car's first ever victory at the Rolex Grand-Am GX race at Road Atlanta. The win marks the first ever for Mazda's diesel-burning, production-car based Skyactiv-D racer, and the first win for a diesel-powered car in a Grand-Am event.
In fact, it was a particularly good day for the Mazda Motorsports team, as a Mazda6 also picked up the third finishing spot at Road Atlanta. Director of Mazda Motorsports, John M. Doonan, said of the racecar, "We've always said that the best street cars make the best racecars, and, with more than half of the components in the race engine being shared with the street engine, this program is a solid proof-point."
SpeedSource Engineering, which helped to build the Mazda6 racer, was greatly heartened by the car's performance in just it's fourth-ever race. Owner Sylvain Tremblay called the victory, "a tribute to the thousands of hours of hard work over many months," continuing, "The normal plan with a new car is to spend the first year in development, the second year seeking race wins, and challenging for a championship in year three. We are already at our year-two status after four races. We can't wait to get to the Belle Isle course in Detroit for round five."

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.
