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.

Junkyard Gem: 1998 Suzuki Swift, Schnorchel Edition

To enable the use of internal-combustion engines underwater, German submarines during the later years of World War II used a pipe system swiped from the Dutch to suck in air and spit out exhaust. This rig was known as the Schnorchel, and a similar setup can be used on modern trucks to keep the engine from inhaling water or dust during river-fording or off-roading. In fact, you can buy a new Ford Bronco with a factory schnorchel (or snorkel, if you prefer the English spelling) right now. Purchasers of new Suzuki Swifts, however, had no such factory — or even aftermarket — option, and so the final owner of today's Junkyard Gem had to fabricate one using hardware-store components. Yes, this is a fully functional air-intake snorkel, made from PVC pipe and entering the engine compartment via not-so-precision holes sliced through the fender and inner fender. Once in the engine compartment, the pipe connects directly to the engine's throttle body. Sure, for serious underwater use you need to waterproof the distributor plus any sensitive electrical components, not to mention find some way to keep water from getting into transmission vents and the like. We can assume, however, that this snorkel wasn't intended for sustained underwater use. Other limitations of the Swift as an off-road machine, such as suspension design, ground clearance, and lack of four-wheel-drive, may have become apparent once the snorkel was installed. There are some wheel flares installed, to enable the use of oversized wheels and tires. The Swift is the same car as the Suzuki-built Geo Metro, which became the Chevrolet Metro starting in the 1998 model year. Known in its Japanese homeland as the Cultus, these cars were sold in every far-flung corner of the world. It appears that you could buy a new Cultus (with Margalla badges) in Pakistan as recently as a few years ago. This isn't the first interestingly modified second-generation Swift I've found in a Denver-area car graveyard in recent years. Perhaps the "Slokyo Drift" 1996 Swift was modified by the same person. There's just something about a tiny, fully depreciated car that inspires creativity. The 1998 Geo Metro was available with either a 1.0-liter three-cylinder engine or a 1.3-liter four-banger, but every new Swift sold here that year was a big-block car with the 1.3 and its 70 horsepower. This one even has the five-speed manual transmission, for added driving fun. Just 166,280 miles on the clock.

Pentagram aims to cut through the noise of EV sound design

What does an electric vehicle sound like when it goes from 0 to 60, when it signals a turn, when it’s powered down for the night? EV motors have fewer parts and are therefore incredibly silent, which presents safety concerns for drivers who recognize speed by sound and pedestrians who canÂ’t hear an approaching vehicle.  In 2019, regulators in Europe and the U.S. began requiring EVs to have warning sounds, but they left it up to the car manufacturers to choose those sounds. Many have taken the new legislation as an opportunity to not only create a branded sound, but also to stir up some marketing hype by enlisting famous musicians to compose the noise of an electric engine. Hans Zimmer created the Blade Runner-esque sound concept for BMWÂ’s i4 electric sedan, and, strangely, Linkin Park is creating EV sounds for BMW.  Sound designer Yuri Suzuki, a partner at design consultancy firm Pentagram, recently conducted a research project into the crucial role electric car sound has on a userÂ’s safety, enjoyability, communication and brand recognition, out of which he developed a range of car sounds. Suzuki says that while some automakers have chosen beautiful and interesting car sound designs, chasing celebrity clout is not the way to go when designing the sound behind serious machines.  “We really have to design carefully based on the psychological effects on a human,” Suzuki told TechCrunch. “ItÂ’s all about the relation between the human being and the machine itself.” Suzuki says smart sound design can help ease the difference between human and car by providing a shared language. Based on surveys he conducted, Suzuki came up with two new skeuomorphic electric engine sounds as well as adaptive sounds that reflect the time of day and the location of the drive.  His engine sounds are reminiscent of internal combustion engine revs, providing both drivers and pedestrians with a recognizable indication of speed increasing and decreasing. The sounds are placed at different pitches: one quite low, like a spaceship taking off; the other a bit higher, like a hovercraft vertically ascending. Audi, Ford and Jaguar Land Rover have also chosen to make futuristic copies of gasoline engines for some of their new electric vehicles.  SuzukiÂ’s sound design also includes in-car sounds, like powering on, turn signals or horn honking, that use AI to adapt to the time of day.
