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.

United States drivers buying fewer Mexican-made cars

Crossovers and pickup trucks are not only growing in market share, they're also more profitable than cars. A crossover on the same platform as a sedan retails for thousands more, despite similar components. It's one of the reasons we've seen automakers rapidly shifting production of their sedans and hatchbacks to Mexico, where cheap labor preserves the thin profit margins on these inexpensive vehicles. But as the market continues to shift in the United States, Mexico is getting burned by its lack of product diversity. The country's auto exports, which are heavy on cars, suffered a 16-percent drop last month, Automotive News reports. In total, year-over-year exports fell from 233,515 to 197,020 last month, while year-to-date exports are down by 7.4 percent, from 922,029 to 854,118. The number one culprit? America – which usually accounts for 75 percent of Mexico's exports – and its appetite for crossovers and pickup trucks bolstered by cheap gas prices. While Mexico does build some light truck models – AN specifically calls out the Ram 2500, Honda HR-V, GMC Sierra, and Toyota Tacoma as export leaders – the vast majority of vehicles rolling out of its factories are sedans and hatchbacks. In fact, the three biggest drops in Mexican exports came from companies whose south of the border factories only build cars – Ford (Fusion/Lincoln MKZ and Fiesta), Mazda (Mazda3), and Volkswagen (Golf and Jetta). Mexican Automotive Industry Association President Eduardo Solis told AN the export shortfall will likely be sorted out sooner rather than later, thanks to a pair of new factories – a Kia car factory and an Audi SUV plant – that are coming online by year's end. The two facilities will add around 100,000 vehicles to the country's export totals, which Solis said should leave the industry on the verge of breaking another export record in 2016. But how sustainable will these record-breaking years be? Slapping an "Hecho en Mexico" sticker on a new German SUV won't be enough to change the fact that Mexico's product mix is tilted too heavily towards body styles that are not growing in volume. Mexico's record-breaking export years probably aren't at an end, but we'd argue they're certainly under threat.

Patent application suggests Mazda rotary return

A recent patent application by Mazda reveals that the Japanese automaker is still working on the rotary engine. This could in fact be the Skyactiv-R engine found in the RX-Vision concept from the 2015 Tokyo Motor Show. As with anything Wankel-related, nothing is certain until Mazda makes a production commitment. But this filing suggests that serious development is happening in Hiroshima. The 2011 Mazda RX-8 was the last rotary-powered car you could buy in America. Slow sales, poor fuel economy, and tighter emissions standards prevented Mazda from committing to a follow-up. But the fundamental principles of the rotary - compact size and light weight - perfectly fit Mazda's Skyactiv ethos. (For an explanation of how rotaries work, click here.) In this new engine the intake port sits at the bottom of the engine with the exhaust port on top instead of the other way around. That allows for lower mounting, which improves a car's center of gravity. This rotary is also turbocharged. Putting the turbo up high helps ensure it doesn't get in the way of any body or chassis crossmembers. The implication of those claims is that somebody is thinking about how to put this engine in a car. There are other benefits as well. The short path from the exhaust port to the turbo ensures minimal turbo lag. It also allows for a close-mounted catalyst on top of the enigne, which will help emissions. Another innovation in this new engine is a triangle-shaped rotor that covers part of the exhaust port. This allows for different exhaust flow characteristics. The filing claims that that two of the four orientations allow for less airflow resistance in the exhaust port. As in previous Mazda rotaries, there are two spark plugs to manage ignition timing and combustion. But unlike in the 16X concept, Mazda's last public display of such an engine, the new rotary uses port fuel injection. Keep in mind this is only a patent application. A Mazda spokesperson refused to comment on future product, but commented "As we stated at the Tokyo motor show, Mazda is doing all that it can to bring a rotary to the market." In the meantime, keep your RX-7 prayer candles lit and hope for the return of the rotary before the end of the decade. You can bide your time by reading the entire application here.
