Mazda just restored the 787B's forgotten older brother

Among Mazda's many racecars, none is as famous as the 787B, and for good reason. The 787B remains the only Japanese car and the only rotary-powered car to win overall at the 24 Hours of Le Mans. It wasn't Mazda's only successful endurance racer, though. Before the 787B, there was the 767B. Mazda's 767B racecars competed in the IMSA GTP class at endurance races throughout 1989. They featured 630-horsepower four-rotor engines and were very successful in their class. This newly restored car took first and second place class finishes in five of the six races it participated in, and each finish was in the overall top ten. The one exception was a DNF in which the transmission failed. Twenty-five years after the 767B's glory days, Mazda initiated a complete teardown and restoration of the aged car. The work was done by Downing Atlanta and supervised by former Mazda racers Rick Engman and Jim Downing. (Fun fact: Downing was one of the designers of the HANS device.) The shop has also restored other racecars for Mazda, including one of the 787Bs. The car went through a two-year rehab and will make its track re-debut at the Monterey Motorsports Reunion. The event takes place next weekend at Mazda Raceway Laguna Seca where the track will once again feature the angry shriek of a competition-grade rotary engine.

Asian automakers still reluctant to use more aluminum

There's a logical progression of technology in the auto industry. We've seen it with things like carbon-ceramic brakes, which use to be the sole domain of six-figure sports cars, where they often cost as much as an entry level Toyota Corolla. Now, you can get them on a BMW M3 (they're still pricey, at $8,150). Who knows, maybe in the next four a five years, they'll be available on something like a muscle car or hot hatchback. Aluminum has had a similar progression, although it's further along, moving from the realm of Audi and Jaguar luxury sedans to Ford's most important product, the F-150. With the stuff set to arrive in such a big way on the market, we should logically expect an all-aluminum Toyota Camry or Honda Accord soon, right? Um, wrong. Reuters has a great report on what's keeping Asian manufacturers away from aluminum, and it demonstrates yet another stark philosophical difference between automakers in the east and those in the west. Of course, there's a pricing argument at play. But it's more than just the cost of aluminum sheet (shown above) versus steel. Manufacturing an aluminum car requires extensive retooling of existing factories, not to mention new relationships with suppliers and other logistical and financial nightmares. Factor that in with what Reuters calls Asian automaker's preference towards "evolutionary upgrades," and the case for an all-aluminum Accord is a difficult one. Instead, manufacturers in the east are focusing on developing even stronger steel as a means of trimming fat, although analysts question how long that practice can continue. Jeff Wang, the automotive sales director for aluminum supplier Novelis, predicts that we'll see a bump in aluminum usage from Japanese and Korean brands in the next two to three years, and that it will be driven by an influx of aluminum-based vehicles from western automakers into China. Only time will tell if he's proven right. News Source: ReutersImage Credit: Sean Gallup / Getty Images Plants/Manufacturing Honda Hyundai Mazda Nissan Toyota Technology aluminum

Mazda rumored to bring rotary-powered RX-9 concept to Tokyo

Stop us if you've heard this one before: Mazda will bring a rotary-powered sports car to the next big auto show. Okay, so we stopped for a second, but the show must go on. Following an official teaser image (shown above) late last month, Motoring.com.au has what it claims are renderings of the curvy, two-door coupe – called the RX-9 – that Mazda will bring to the Tokyo Motor Show later this month. The images show a far softer styling than Mazda's current crop of Kodo-inspired vehicles, while the overall look screams of a modern-day Cosmo Sport, the Japanese brand's first rotary-powered vehicle. And though that connection alone might be enough to justify whisperings of a successor to the RX-7 and RX-8, Motoring claims there will be an even more overt sign of this concept's power source. "Look to the Cosmo Sport," an inside source told the Aussie website, signaling that the Mazda stand would feature the vintage two-door. "The Cosmo has no earthly reason for being there unless..." The rotary rumor, if it comes true, won't exactly be what we're use to. While Motoring brings up the previously reported 16X – a 1.6-liter two-rotor – it builds on our 2013 report. According to the Aussies, the new engine could feature a two-stage electric turbocharger, be paired with a hybrid powertrain, offer up to 450 horsepower, and we're guessing, be hilariously complicated. Joking aside, it sounds like Mazda's goals here are admirable. A rotary-equipped sports car that could counter the 1.3-liter RX-8 engine's appetite for fuel and improve on its mediocre low and mid-range torque would be interesting indeed. As for those renderings, Motoring has front and rear three-quarter images. Comparing the rear with our original teaser leaves the look open to interpretation, but after seriously upping the exposure on the teaser (thanks Photoshop), the taillights and overall profile shape look to be a spot-on match. In front, the long hood shares some Kodo elements, like the headlights and grille, but its undeniable coupe shape – a long hood and very short deck – are far more organic and, dare we say, calm, than Mazda's other vehicles. You can take a closer look at the renderings over at Motoring's website. Do that, and then head back and let us know what you think of these RX-9 rumors. Is Mazda finally going to be bringing a rotary back to market?
