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 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.

Mazda Raceway gets first new MX-5 Cup as pace car

Mazda's motorsports department officially finished the first example of its new MX-5 Cup racer. But while the rest of the fleet will be used in the Global MX-5 Cup championship, this initial unit has been designated for another purpose. It's been dedicated to serve as the new pace car for Mazda Raceway Laguna Seca. Based on the latest ND-generation MX-5, the Cup racer was previewed in racing spec this past November ahead of its debut at the SEMA show. Though we've still yet to see the final spec sheet, it clearly benefits from key upgrades to the rolling stock, not to mention the added roll cage, racing buckets, and more. The pace car also features emergency lighting and a livery designed by Mazda and applied by Sticky Fingers Design out of Huntington Beach, CA. The beefed-up little roadster will join a cadre of pace cars used at the legendary Northern California circuit. Other pace cars in the fleet include a Mazda6, RX-8, CX-5, and the previous Miata. The season is winding to a close at Laguna Seca, with the Pirelli World Challenge finale and Mazda Road to Indy still set to take to the track next month.

(August 13, 2015) – Mazda Motorsports used the annual car-fest known as the Rolex Monterey Motorsports Reunion to roll out the first production 2016 Mazda MX-5 Cup race car. This particular vehicle is guaranteed to lead races as it will be the newest pace car in the Mazda Raceway Laguna Seca fleet of Mazda safety vehicles. The 2016 Mazda MX-5 Cup race car follows a 26-year history of the MX-5 Miata in motorsports. The first race cars to be sold to customers will be used in the 2016 Global MX-5 Cup, known in the U.S. as the Battery Tender Mazda MX-5 Cup. With the 2016 racing season still many months away, placing the first production race car into pace car duty allows Mazda to gather additional durability data while showcasing it in front of one of the most influential motorsports crowds of the year. "For Mazda, this weekend is the perfect blend of past, present, and future," noted John Doonan, director of motorsports for Mazda North American Operations. "We are celebrating our motorsports heritage on the track with our vintage race cars.
