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.

2016 Mazda MX-5 Miata 2.0L First Drive [w/video]

The 2016 Mazda MX-5 Miata is easy to comprehend. It is an enthusiast roadster in its purest form. There's no need for any sort of sales pitch. You don't have to ramp up in order to get people excited about it. Say the words "new Miata" to anyone who cares about cars, and you've immediately got their attention. And now that I have yours, I'll to cut right to the chase. It's brilliant. That's a fact I've known for a while. I drove the Japanese-spec ND Miata in Spain earlier this year, with the 130-horsepower, 1.5-liter engine that we aren't getting in the United States. The new Miata is a modern day reincarnation of the original NA that stole our hearts in 1989. It's smaller and lighter than the outgoing NC, yet boasts more interior room. It's comfortable. It looks great. And it drives like a Miata should. In other words, it's perfect. So what about this US-spec car, then? It's got more power – 155 horsepower and 148 pound-feet of torque from Mazda's 2.0-liter Skyactiv four-cylinder engine. But it's also heavier. Our car weighs 2,332 pounds, compared to the roughly 2,200 pounds of the 1.5-liter car. Yes, the ND Miata loses 12 hp compared to the outgoing NC, but it's up 8 lb-ft of torque. Plus, according to Mazda, because of the improved powerband, anytime you're under 5,700 rpm the new Skyactiv engine is stronger than the old MZR mill. It's more efficient, too. With the manual transmission, the Miata is estimated to achieve 27 miles per gallon in the city and 34 mpg highway. That a jump of six mpg in both categories compared to the old six-speed. Consider this: The Japanese-spec car uses a 130-hp engine, which I found to be perfectly adequate. The increase in power for the US-spec car mostly just balances out the extra weight, but it also improves performance on the highway. Hit the throttle in sixth gear with the 1.5 and nothing happens. Do the same with the 2.0, and there's movement. Low-end power is far more important in the US than it is in other markets, and that's why our car has the larger engine. "North America is why the two-liter car exists," engineer Dave Coleman told me. Plus, 155 hp power means you eke out the Miata's dynamics at legal speeds. 45 miles per hour in an MX-5 is a far more exhilarating experience than that same speed in any supercar. So yeah, it's not powerful. But to paraphrase Jay-Z, the MX-5 is a super car, not a supercar.

Mazda engineers urging execs for more RWD models

According to Edmunds, Mazda engineers are pressuring the company to create more rear-wheel-drive models, in an effort to better differentiate itself from its rivals. This push is reportedly coming from middle and senior engineers within the company, and these folks at Mazda believe this rear-drive strategy would allow the automaker to produce more distinctive, fun to drive cars. Mazda discontinued the rear-drive (and rotary-engined) RX-8 a few years ago, leaving the MX-5 Miata as the company's only RWD offering.
As enthusiasts, we're fully on board with Mazda offering more rear-drive cars, but unsurprisingly, the company's top management isn't exactly keen on the idea - and with good reason. First and foremost, the cost associated with redesigning fresh architecture for new models would be very high, and considering the fact that Mazda hasn't exactly been raking in the dough lately, an expensive new venture like this doesn't make a whole lot of sense. What's more, Mazda's latest front-drive models - the Mazda3, Mazda6 and CX-5 - have been very well-received, and are helping the company gain sales momentum.
But that doesn't mean there aren't other options. Edmunds reminds us that Mazda is already partnering with Alfa Romeo on the next-generation Miata, and if this collaboration is successful, perhaps the relationship could bear additional fruit. After all, Alfa Romeo is said to be working on returning to its rear-wheel-drive roots, so Mazda's engineers might be able to make a case for more RWD goodness after all.
