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.

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.

Mazda hard at work on Skyactiv 2 engine technology

As Mazda continues the current rollout of its still-new Skyactiv technology, the automaker is already looking at improving its family of engines for even better fuel economy and emissions reductions. Automotive News reports that with stricter fuel economy and emissions regulations planned for 2020 and 2025 in Europe, Mazda will likely release engines with next-generation Skyactiv 2 technology by the end of this decade, and Skyactiv 3 units just five years later.
The latter is expected to focus on improved engine cooling and lessening energy losses, but the big news in AN's report is that the next-gen Skyactiv 2 engines will use Homogeneous Charge Compression Ignition, or HCCI. This type of ignition is very similar to how a diesel engine operates (with high compression and using the compression stroke for fuel combustion rather than spark plugs), a method said to provide a cleaner and more efficient fuel burn - to the tune of a 30-percent improvement in fuel economy compared to current Skyactiv engines. Other automakers, including Hyundai, have already announced they are developing HCCI powerplants with similar technology and characteristics, so Mazda likely won't be a lone wolf here.
Equipped with HCCI technology, Mazda figures to be able to compete with larger automakers in terms of fuel economy and emissions without resorting to hybrid powertrains, continuously variable transmissions or automatics relying on more forward gears (eight or more) for optimal efficiency. Some of the challenges of HCCI, according to AN, include the need for better engine cooling, risk of misfire at high and low rpm and uneven engine performance based on fuel properties.
