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.

Next Mazda MX-5 Miata to weigh a ton(ne), literally

Looking at recent spy shots of the fourth-generation Mazda Miata, it's obvious this sporty little roadster will grow in size compared to the current model, but it's also going on a diet. At the Tokyo Motor Show, Auto Motor und Sport sat down with Mazda executive Kiyoshi Fujiwara, who gave a little more insight into the Miata's redesign.
Fujiwara said that they're aiming for a curb weight of a tonne (metric ton), which is 1,000 kilograms or right around 2,200 pounds, for the next-generation Miata. This would make the roadster at least 300 pounds lighter than the current NC Miata, but still about 200 pounds heavier than the original NA.
There is no indication as to how Mazda will go about removing that much weight from the bigger car, but with as popular as the power retractable hard top (PHRT) model is on the current car, the new Miata may ditch this feature to lose its weight. Improving the power-to-weight ratio appears to be a key goal of the Mazda team, so we also wouldn't be surprised to see a more powerful engine underneath the longer hood.

Flyin' Miata's 525-hp V8-powered ND finally hits the streets

Flyin' Miata, in its valiant quest to turn Mazda's roadsters into small, Japanese Corvettes, has finally finished its first V8-powered ND Miata. The company has been slowly teasing us with images and videos for months, but it wasn't until this week that the car finally made it to the streets. As soon as the current ND generation Miata was released, Flyin' Miata started the work to shoehorn a GM LS3 under the hood. The company has a history of building brutish, V8-powered Miatas. It sells everything from minor parts to full V8 conversion kits. For those with the cash that prefer to avoid the hassle, Flyin' Miata will sell you a complete, turn-key car. The price hasn't been finalized, but customers should expect to pay about $50,000 plus the cost of the MX-5. The new car has a worked-over LS3 that sends 525 horsepower to the rear wheels through a Tremec T56 transmission. Flyin' Miata says the rear differential comes from a V8 Camaro. Other new bits include exhaust, suspension, brakes, and a roll cage. Flyin' Miata tells us that the V8-swapped ND will weigh 2,592 lbs, a little more than 200 lbs more than the porkiest stock Miata. Despite twice as many cylinders and more than three times the displacement of the stock four banger, the LS3 V8 is a relatively small and lightweight engine. The finished car has a 53:47 front to rear weight distribution. Final touches are being finished, but cars and kits should be available soon. This article has been updated with some info straight from Flyin' Miata. Thanks, Keith! Related Video: News Source: Road & Track, Flyin' Miata Mazda Convertible Performance flyin miata
