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.

Evo pits Toyota GT86 vs. Mazda MX-5 Miata

The latest Deadly Rivals episode from Evo gets the Mazda MX-5 Miata and Toyota GT86 (our Scion FR-S) on track for a shakedown and a whole lot of drifting with Dan Prosser behind the wheel. The UK-spec coupes have slightly different power ratings than ours, but it's all close enough to be comparable. Their Miata has 158 horsepower (ours has 155), 148 pound-feet of torque, takes 7.3 seconds to run from naught to 60 62, and costs 22,695 pounds. The GT86, on the other hand, lists a 7.6-second dash to 60 62, and a base price of 25,000 pounds. The GT86 also weighs 400 pounds more than the Mazda. That's true in the States, too – curb weight for our MX-5 is 2,332 pounds, whereas the Scion FR-S comes in at 2,758 pounds. Both cars lauded for excellent shifting, but one of them has a better front end, a sweeter engine note, more controllable cornering behavior, and is faster by a tenth of a second around the test track. And Prosser doesn't mention it, but one has a lot more body roll. But it takes more than all that to make a winner, so check out the video above to see which is which.

Mazda6 diesel engine delayed over low performance, still coming

Oh Mazda... we had many hopes for the promised diesel four-cylinder in the Mazda6, but those have remained largely unfulfilled, as the oil-burning powerplant has failed to appear on dealer lots following its 2012 LA Auto Show announcement. Despite engineering issues that forced the company to announce that the program was delayed back in September 2013, Mazda remains adamant that the 2.2-liter Skyactiv-D is still coming to our shores. "We're still very much committed to diesel," Mazda's North American CEO, Jim O'Sullivan, told Automotive News. "We are still working on getting the performance aspects up to where we want them, and we do have a plan – an engineering road map – to get it done." According to AN, Mazda's initial plan with the 2.2-liter diesel was to build an engine so clean it could get by without an aftertreatment system, which generally accounts for the price premium of diesel engines versus their gas counterparts. The new system has come with performance issues, though, necessitating the delays. "If [we were] a commodity brand and didn't care about that, it would be on the market right now," O'Sullivan told AN. "But I know the people were expecting something from us, expecting certain drive characteristics and performance, and I didn't want to disappoint them." While O'Sullivan's defense of the diesel Mazda is admirable, the exec stops short of giving us an indication of when the new engine will finally arrive.
