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 iK-2 and iM-4 concepts suggest future style

Suzuki might no longer sell cars in the US, but the Japanese brand is showing that it's still vibrant in the rest of the world by unveiling two concepts at the Geneva Motor Show. The models also debut some the company's future technology and preview the look of upcoming production vehicles. The iK-2 Concept (top) foreshadows a future compact hatchback, and Suzuki is clear that a production version is due to arrive in Europe in 2016. Its styling is a flowing take on the traditional five-door hatchback, especially around the front fenders. More importantly, the model also rides on the Japanese brand's next-gen platform that promises to be lighter, more rigid, offer better efficiency and improve safety. Power comes from the new Boosterjet engine, but despite the speedy name, it's a 1.0-liter, direct-injected, turbocharged three-cylinder. A mild hybrid system is also going to be offered on the iK-2, but outputs for the powertrains aren't specified yet. The more interesting of the pair visually is the Suzuki iM-4 Concept (pictured inset) that imagines a simple, mini offroader, possibly a replacement for the Jimny. It's on the same platform as the iK-2 but with a much higher ride height and quirky styling. The grille and headlight configuration take inspiration from a pair of sunglasses, Suzuki claims. The model also features broad, fairly unadorned surfaces and short overhangs. The whole look just gives the impression of a little mountain goat ready to go anywhere. Power goes to all four-wheels thanks to a 1.2-liter engine and mild hybrid system.
