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, Suzuki, Yamaha — more vehicle data fabrication found in Japan

TOKYO — Mazda, Suzuki and Yamaha improperly tested vehicles for fuel economy and emissions, the Japanese government said on Thursday, revealing fresh cases of compliance failures by manufacturers. The results came to light after the Japanese government had ordered the automakers to check their operations after revelations of improper testing at Subaru and Nissan last year. The conduct of automakers globally has come under intense scrutiny after Germany's Volkswagen AG admitted in 2015 to installing secret software in hundreds of thousands of U.S. diesel cars to cheat exhaust emissions tests, and that as many as 11 million vehicles could have similar software installed worldwide. In the Japanese cases, the carmakers have not broken any laws or prompted massive recalls. But a growing list of improprieties has tarnished the image of the country's manufacturing industry for high-quality products and efficiency. Suzuki, Mazda and Yamaha cleared vehicles for emissions or fuel efficiency even in cases where they were tested under invalid conditions, the ministry said in a statement. The errors related to slight deviations in the speed of the vehicles during testing that should have invalidated the test results. The automakers examined tests they had conducted over different periods of time, and in Suzuki's case they stretched back to 2012. None of the automakers found significant problems with actual emissions and fuel economy performance of the vehicles, which were destined for sale in Japan, and do not plan any recalls. Suzuki, Japan's fourth-largest automaker, said that of 12,819 sample vehicles tested for fuel economy and emissions since June 2012, around 50 percent of them had been inspected improperly. "I deeply apologize and will lead efforts to prevent recurrence," Suzuki Chief Executive Toshihiro Suzuki told a news conference. Mazda said there were irregularities in 4 percent of similar inspections on its cars, or just over 70 vehicles. In Yamaha's case, irregularities were found in 2 percent of inspections, or just a handful of vehicles. Both Mazda and Yamaha apologized. Suzuki and Yamaha shares fell 6 and 5 percent, respectively, and Mazda shares were down 1 percent, underperforming a steady benchmark Nikkei average. In July this year, Nissan admitted it had improperly measured exhaust emissions and fuel economy for 19 vehicle models sold in Japan.

2021 Mazda3 Turbo First Drive | A fun luxury alternative

After seven years and an entire generation, there is finally another turbocharged Mazda3. But Mazda will be the first to tell you that it’s not, by any means, a successor to the rambunctious Mazdaspeed3, hence the lack of the name. Having driven it, weÂ’ll be the second to tell you the same: this is definitely not a Mazdaspeed3. ItÂ’s an altogether different beast, but itÂ’s still a good drive, and helps make the 3 a credible, budget alternative to an entry-level Audi or Mercedes. The turbocharged 2.5-liter engine is mostly the same one that Mazda has used in the CX-9 and turbocharged CX-5. It makes the same 227 horsepower and 310 pound-feet of torque on regular fuel (or 250 hp and 320 lb-ft of torque on 93 octane), but it's been tweaked to fit in the Mazda3Â’s smaller engine bay. The biggest change is the use of an air-to-water intercooler integrated with the intake manifold that reduces the amount of plumbing. As a bonus to helping the engine fit, Mazda notes that the overall intake piping length is shortened, which should improve responsiveness. While we canÂ’t speak to the improvement, the engine's response and power delivery is incredibly smooth. It feels about as close as a turbo engine can get to being like a supercharged or naturally aspirated engine. ItÂ’s easy to dial in exactly how much power you want, and thereÂ’s never an unexpected rush of turbo boost. All that torque is available low in the rev band, too, so it provides effortless acceleration, especially considering how much less mass the 3 has compared with its turbocharged crossover siblings. The smooth, relaxed acceleration is in keeping with the upmarket aim of the Mazda3 Turbo, and even compares favorably with powerplants from Audi and Mercedes. Those engines are similarly responsive, but deliver their torque in a fast rush, rather than the more gentle deployment of the Mazda. The turbo engine doesnÂ’t lose much in efficiency, either. Overall fuel economy drops by just 1 mpg from the naturally aspirated all-wheel-drive Mazda3s. The sedan gets 27 mpg overall and the hatchback gets 26. The engineÂ’s only real downside is that itÂ’s a little noisy under acceleration, emitting a low growl. Arguably the smooth power delivery takes away some excitement often associated with small, turbo cars, but as we said before, this isnÂ’t meant to be a Mazdaspeed successor. Like the engine, the drivetrain is closely related to other existing Mazdas.
