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.

Mazda to reveal MX-5 Miata Club Edition in New York

Mazda is bringing a new version of its latest MX-5 Miata to the New York Auto Show. And while it's giving us very little to go on at the moment, from what we can tell so far, it looks promising. For starters, it's called the Club Edition, which speaks to us of enhanced performance – particularly on the track. For another, the statement below highlights the "maximum driving enjoyment" the existing MX-5 was "designed to deliver," and then proceeds to claim that the Club will "amplify that experience, harking back to the early lightweight sports cars that inspired it, but serving as a beacon for the future as a thoroughly modern, sophisticated package." Hopefully, then, it'll serve as some sort of road-going mid-point between the stock version and the Global Cup racing concept pictured above. We'd expect the 2.0-liter four-cylinder engine to carry over likely unchanged with its 155 horsepower and 148 pound-feet of torque, but with the potential addition of a stiffened suspension, upgraded rolling stock, revised aero, enhanced cockpit and maybe some excess weight trimmed out – although the new Miata doesn't have much to lose as it is. In any case, we're excited.

The 2016 Mazda MX-5 Miata Club edition, that is. Mazda North American Operations (MNAO) will be introducing the North American-spec MX-5 Club next week at the New York International Auto Show. The MX-5 Club represents the most aggressive road-going iteration of Mazda's fourth-generation flagship roadster. The 2016 MX-5 sheds approximately 150 lbs. from its predecessor through use of lightweight, efficient SKYACTIV®1 TECHNOLOGY, now weighing 2,332 lbs. when equipped with the standard SKYACTIV-MT six-speed manual transmission (2,381 lbs. with the six-speed automatic). Powering all North American models will be a 2.0-liter SKYACTIV engine, rated at 155 horsepower and 148 lb-ft of torque. Shorter than the first-generation MX-5 that initially graced U.S. shores in 1989, yet wider than the outgoing model and with its engine lower and farther back in its chassis, the 2016 MX-5 is designed to deliver maximum driving enjoyment.

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.
