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.

Mazda6 Skyactiv-D Racecar ready to bring diesel to Grand-Am

It may not be quite as radical as some of the company's past rotary racers, but the new Mazda6 Skyactiv-D racecar does have a notable powertrain underhood: the automaker's brand-new clean diesel four-cylinder engine.
Three of these new diesel-powered Mazda6 racers will take to the track in the Grand-Am GX class of the upcoming 2013 Rolex 24 at Daytona on January 26, with five drivers on each team. The car you see above, number 70, is sponsored by Mazda's longtime motorsports partner, SpeedSource.

Mazda refurbishing this NFL running back's 22-year-old daily driver

I don't actually care for the Washington Redskins (which is a good thing, considering the start to their season this year), but I love their running back, Alfred Morris. Why? Well, to start with, Morris helped deliver a dominating 10-3 season for my fantasy football team last year after a flash of prescience saw me pick him up off the waiver wire in Week 1 (hit me up on Twitter if you need fantasy sports insight, guys, I'm sort of like the Ruxin of Autoblog).
Morris is also pretty endearing because of his loyalty to his car, Bentley. Hold up - that's not to say the running back has splashed out on a Continental GT or a Flying Spur. No, Morris gave his much-loved 1991 Mazda 626 the tongue-in-cheek name "Bentley" while he was still a student at Florida Atlantic. One 1,613-rushing-yard rookie season and a $2.2-million contract later, and Morris is still using his Mazda as his daily driver. It might be easy to assume that the young player is simply being really prudent with all of his newfound wealth, but the guy really just has a thing for his five-speed-manual 626.
And Mazda, of course, loves the story of Morris' affection. In an effort to keep his 626 running strong and looking good, the company's Washington D.C.-area dealers have agreed to refurbish Bentley back to its original showroom freshness. Rather than spoil the classic (?) lines of the 626, the Mazda folks are essentially restoring the car for Morris. The cracked dash will be swapped out for a factory replacement, the engine and transmission given a thorough going-over and the whole vehicle generally made as fresh as Will Smith circa 1991. Bentley is expected to be completed and rolling through the capitol city by October 15, and in the meantime, Morris has been driving around in a new 2014 Mazda6 loaner car.
