Fourth-gen Mazda MX-5 Miata could get turbo power later in life

While there's a lot to love about the new Mazda MX-5 Miata, its debut was met by a vocal group of enthusiasts who derided the fourth-generation roadster's reduction in power output. The new model only puts out 155 horsepower, down from 167 in the NC. A report from Australia, though, claims Mazda may yet address the less potent output of the ND. Things started earlier this year, as Motoring.com.au tells it, when Mazda's global PR boss, Kudo Hidetoshi, hinted that a turbocharged or Mazdaspeed model "will definitely" be considered. Then last month at Goodwood, the ND's program manager, Nobuhiro Yamamoto, said complainers were welcome to get their thrills elsewhere. Recognizing this contradiction among Mazda's brass, Motoring asked Yamamoto-san again about his statements, which he seemed to walk back. "It's not a conflict [between statements made by Yamamoto and Hidetoshi]," Yamamoto said, indicating that his statements were made in relation to the new MX-5's launch. "Kudo-san talked about this in terms of a 10-year lifespan, but when I was asked the question right after the launching of the ND, I said 'we have no plan to have a turbo at that point in time.' That is what I meant." Seeking an opening, Motoring pushed the Japanese engineer on the chances of a more potent MX-5, perhaps without a turbocharger. "If you could achieve what we want, to which is great response, very light and powerful with great performance feel with natural aspiration, then we don't need a turbo," Yamamoto said. "But if we want more power because we don't get satisfied with natural aspiration then we may think about the turbo." Related Video:

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
