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.

Japanese motorcycles moving into forced induction

While turbocharging and supercharging may be nothing new in the automotive industry, motorcycle engines are almost always naturally aspirated. But even that's beginning to change. At the Tokyo Motor Show last week, two major Japanese companies showed off new forced-induction motorbike engines.
Kawasaki rolled in with a supercharged four-cylinder motorbike engine. It offered little in the way of details, disclosing only that the turbine blades were developed in-house to withstand the heat and vibration of spooling up at motorbike speeds.
Suzuki is taking a different approach, however. Its Recursion concept bike packs a turbocharged 588cc two-cylinder engine with a turbocharger and intercooler. The compact package churns out just under 100 horsepower and 74 pound-feet of torque, packaged into a motorbike that weighs just 384 pounds dry.

Suzuki: 'No comment' on returning to the U.S. with the Jimny

It is impossible not to love the Suzuki Jimny. A prototypical cute ute, with equal parts cuteness and utility, it not only defined its segment, it became a cult classic. Now, it's back, but unfortunately unlikely to come to the American market as the Jimny, Samurai or anything else. "We have no comment on the Jimny or Suzuki returning to the U.S. market," says Nathalie Geslin, a spokesperson for Suzuki in France, from the floor of the Paris Motor Show, where the adorable Jimny made its recent premiere. "For that you'll have to ask Suzuki headquarters in Japan." In France, this is what is known as Le Brushoff. Geslin did confirm that, in the markets around the world where the Jimny will appear, it will be available only in one spec: an adaptable, RWD/AWD, closed hardtop with a manual transmission with available Low range, and powered by a 102-horsepower 1.5-liter gasoline engine. "Suzuki has eliminated diesel motors from their whole range," she said, a notable move and a trend flowing from the fuel's immutable high particulate and noxious gas emissions, and growing global sensitivity to their effects. Actually, she tells us, there will be one other spec. "In the Japanese market, there will be a Kei Car version, an actual smaller Kei Car, which means it will be powered by a motor of less than 600cc." Just 1,500 of these cars are expected to be sold in the French market, mainly to people who, according to Geslin, are not off-reading aficionados, but "People who go off-roading in their normal life, who live in the mountains or work in an area with rugged conditions." This sounds to us like a description of every small-scale goat cheese producer in the White Mountains in rural Vermont, every boutique mountainside vintner in Sonoma county, every yellow micro-beet farmer in the Wisconsin Dells. And all of us who live in four-season climates and love the outdoors but think a Jeep is perfect except that it's a third too large. Like the Jeep, the Jimny is retro cool without being retro. It is just itself. And we need it. If it takes only 1,500 potential buyers in France to allow it to be sold there, how many does that translate to in America? If all of us start emailing Suzuki headquarters every day to beg for it, maybe we can find out. Related Video: This content is hosted by a third party.
