Mazda6 diesel to race at Rolex 24, team and drivers announced

Mazda is getting serious about showing off the Skyactiv-D turbo-diesel four-cylinder engine in the Mazda6. The automaker has just announced it will campaign three diesel Mazda6 racers in the Grand-Am GX class of the upcoming 2013 Rolex 24 at Daytona in a quest to walk away with the company's 24th class win. Mazda partnered with SpeedSource to develop the race version of the new sedan, with Japanese and American engineers lending a helping hand where needed. Meanwhile, Freedom Autosport and Visit Florida Racing/SpeedSource/Yellow Dragon Racing will helm teams of their own.
Each car will make use of a five-driver team for the 24-hour race on January 26. In the interim, you can check out the full press release below for more information as well as the full driver roster. Mazda says we can expect to see the No. 70 SpeedSource car under the lights at the 2013 Detroit Auto Show later this month, as well.

Automakers want to stop the EPA's fuel economy rules change, and why that's a shortsighted move

With a Trump Administration looming, the EPA moved quickly after the election to propose finalizing future fuel economy rules last week. The auto industry doesn't like that (surprise), and has started making moves to stop the EPA. Ford CEO Mark Fields said he wanted to lobby Trump to lower the standards, and now the Auto Alliance, a manufacturer group, is saying it will join the fight against cleaner cars. The Alliance represents 12 automakers: BMW, Fiat Chrysler, Ford, GM, Jaguar Land Rover, Mazda, Mercedes-Benz, Mitsubishi, Porsche, Toyota, VW, and Volvo. Gloria Bergquist, a spokesperson for the Alliance, told Automotive News that the "EPA's sudden and controversial move to propose auto regulations eight months early - even after Congress warned agencies about taking such steps while political appointees were packing their bags - calls out for congressional action to pause this rulemaking until a thoughtful policy review can occur." The EPA was going to consider public comments through April 2017, but then said it would move the deadline to the end of December. That means that it can finalize the rules before President Obama leaves office. The director of public affairs for the Consumer Federation of America, Jack Gillis, said on a conference call with reporters last week when the EPA originally announced its decision that it is unlikely that President Trump will be able to roll back these changes. Gillis also said on the same call that any attempt by the automakers to prevent these changes would be history repeating itself. "These are the same companies that fought airbags, and now promoting the fact that every car has multiple airbags," he said. "These are the same companies that fought the crash-test program, and now are promoting the crash-test ratings published by the government. So, it's clear that they're misperceiving the needs of the American consumer." There are more reasons the Allliance's pushback is flawed. Carol Lee Rawn, the transportation program director for Ceres, said on that call that the automotive industry is a global one, and many automakers are moving to global platforms to help them meet strict fuel economy rules around the world.

Turbocharged 2018 Mazda6 EPA mileage figures released

A few months after the reveal of the new turbocharged variant of the Mazda6, we now know how much more fuel the force-fed family sedan will require. The EPA rating puts it at 31 mpg on the highway, 23 in the city and 26 combined. That is less than the naturally aspirated model with either an automatic transmission or a manual, the former of which gets 35 mpg highway, 26 in town and 29 combined. But the naturally aspirated Mazda6's 184 horsepower and 185 pound-feet of torque are well short of the turbo engine's 250 horsepower and 310 pound-feet. The turbo Mazda6's fuel economy also puts it right in the range of similarly powerful sedans in the mid-size arena. In fact, almost every 2018 2.0-liter turbocharged sedan in the segment gets 26 mpg combined, including Kia Optima, Hyundai Sonata, Chevy Malibu, Buick Regal, and most versions of the Honda Accord, with only a difference of 1 or 2 mpg in city or highway results. The V6 Toyota Camry and Nissan Altima also hit this 26 mpg fuel economy mark. As far as power is concerned, the Mazda6 is also very even with the competition, most of which makes right around 250 horsepower, though the Toyota Camry's naturally aspirated V6 is a class-leader at 301 horsepower. But the 6's advantage is in torque. None of the mainstream family sedans touch the Mazda's whopping 310 pound-feet. The 2.0-liter Honda Accord and Ford Fusion come the closest at 273 and 275 pound-feet respectively. To beat the Mazda6 would require going for the Ford Fusion Sport, which is a unique step up in the segment with a turbocharged V6 making 380 pound-feet. The Fusion Sport takes a serious hit in the fuel economy department, though, getting just 20 mpg combined. Related Video: This content is hosted by a third party.
