Mazda6 GX Grand-Am racer goes where no diesel sedan has gone before

There has never been a four-door diesel sedan in the Grand-Am series, until now: The blunt, bewinged grille of the Mazda6 GX has blown right through that wall. It's said that racing improves the breed, but usually the breed has gone on sale when the racing begins. One of the unusual aspects of the Mazda6 GX, on the other hand, is that while the diesel won't go on sale to the public until later this year, it will already have tasted racing blood by the end of the day. That kind of reversal is more likely found with super coupes like the Lexus LFA and Honda NSX.
Mazda has taken class wins at Daytona's 24-hour race a whopping 23 times since 1975, most recently in 2010 with the RX-8 in the GT class. This year the Hiroshima company decided to show off its SkyActiv technology, then turned things up to eleven by opting for its SkyActiv-D instead of the more conventional SkyActiv-G gas engine to run in the new GX class. It will be joined by competitors like the Lotus Evora and Porsche Cayman in the class, nevertheless, at 2.4 liters, it's the smallest engine on the grid.
Time has not been a friend, either - Mazda said that the first five SkyActiv-D engines off the production line went to Speed Source in Coral Springs, Florida, the company that preps Mazda's race vehicles. Still, race driver Jonathan Baumarito on the #70 car said that although the engine's been on the dyno since February of last year, it's only been in the car for about a month and there have been only a couple of test days.

World Car of the Year finalists announced

To say the 2014 Geneva Motor Show was packed full of news is an understatement as big as the show's home at the Palexpo convention center. Despite everything that we were able to cover during this year's show, there's still more coming out of Switzerland, including the announcement of the finalists for the 2014 World Car of the Year Awards.
We reported on the original list of finalists over three weeks ago, and now, that initial list has been pared down to three finalists for each of the five awards. The finalists were announced at a press conference by frequent Autoblog contributor and co-chair of the awards, Matt Davis (above).
The finalists for the overall title of 2014 World Car of the Year are the Audi A3, the BMW 4 Series and the Mazda3. The World Luxury Car of the Year will be either the Bentley Flying Spur, the Mercedes-Benz S-Class or the Land Rover Range Rover Sport, while the Performance Car of the Year will be awarded to the Chevrolet Corvette Stingray, the Ferrari 458 Speciale or the Porsche 911 GT3 (which, um, yeah...).

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.
