Japan carmakers vouch for safety of some Kobe Steel parts

TOKYO — Four Japanese automakers on Thursday said they found no safety issues with aluminum parts supplied by Kobe Steel Ltd, allaying some concerns that falsified quality data on products from the steelmaker had compromised their vehicles. Kobe Steel shares surged after the car makers' statements, but the steelmaker still has to contend with a U.S. Justice Department probe, while checks continue at hundreds of companies involved in complex supply chains spanning the globe. Japan's third-biggest steelmaker admitted earlier this month it falsified specifications on the strength and durability of aluminum, copper and steel products, along with materials for optical disks. The falsifications stretch back for more than 10 years, a senior executive told Reuters this week. Since then, global automakers, aircraft companies and other manufacturers have scrambled to identify potential hazards in their products. Toyota, Honda, Nissan and Mazda said that hoods and other exterior parts used in their cars which were made from aluminum directly supplied by Kobe Steel were safe. Kobe Steel shares ended the day nearly 7 percent higher but are still down by more than a third since it announced the data falsification. Automakers are still making checks on other parts, including those that they received through their parts suppliers. "We confirmed that the materials satisfy applicable statutory standards, and our own internal standard, for key safety and durability requirements for vehicles," Toyota said in a statement. Toyota, one of the world's largest automakers, identified aluminum plates supplied by Kobe Steel for the hoods and rear hatches of Toyota and Lexus brand vehicles. Though outside the automaker's specifications, they were still safe to use. While Subaru and other carmakers said they were still investigating the issue, the announcements by Toyota, Honda, Nissan and Mazda suggest that Kobe Steel's cheating scandal may have a limited impact on product safety."SERIOUS SITUATION" Nonetheless, the company's fate hangs in the balance while checks are being carried out. It must report to Japan's industry ministry by around the end of next week on any safety concerns and provide a more extensive account of the problems a fortnight later. Industry leaders have reached a consensus that Kobe Steel is in a "serious situation," a senior Japanese manufacturing executive told Reuters.

Junkyard Gem: 1986 Mazda 323 DX Hatchback

Mazda built generation after generation of the Familia, starting with the Giugiaro-styled machines of the 1960s. The first Familia that sold well in North America was called the GLC (for "Great Little Car"), and it began life as a rear-wheel-drive cousin to the RX-7 before the Familia went to a front-wheel-drive platform for the 1981 model year. The GLC name stuck around these parts through 1985 — and I've documented a few discarded examples of these now-rare machines during my junkyard travels — before getting the 323 name starting in the 1986 model year. It's no sweat to find 1990s 323s in junkyards, but I've been scouring the car graveyards of the land for the elusive early 323 and, finally, found this moss-encrusted '86 in a San Francisco Bay Area yard. BMW popularized the lower-case-i nomenclature for fuel-injected cars with the first 3-Series back in the 1977 model year, and Mazda wasted no time making "1.6i" badges to tout the futuristic technology under the hood of their low-priced econo-commuter a decade later. At a time when most Civics had carburetors (and the notorious "Map of the Universe" diagram to untangle the underhood vacuum lines), the electronically fuel-injected engine in this car was a major selling point indeed. It wouldn't be many more years before the wretched Subaru Justy was the final carbureted Japanese car available in America, but this 1.6-liter B6 four-cylinder (which evolved into the engine that, flipped 90 degrees, powered the early Miatas) was high-tech stuff for a cheap car in 1986. Just 84 horsepower, but they were clean and reliable horses. In the middle 1980s, the common perception in North America was that you had to buy a Honda or Toyota if you wanted an affordable car that could make it to 200,000 miles. This 323 held together just as well as most Tercels or Civics from 1986. Of course, I've seen a junkyard RX-7 with 393,854 miles, so you just never know. When you see lots of moss and lichens on a car in a Northern California junkyard, you know it spent years — maybe decades — languishing in a shady outdoor spot. Perhaps this car racked up 20,000 miles per year slogging through a harrowing Lodi-to-Sausalito commute, then got parked and forgotten in 1996. We'll never know. With the optional automatic transmission — nearly every early 323 I've seen had the 5-speed manual — this car wouldn't have been much fun to drive. Point A to Point B would have been fine, though.

Mazda will introduce a groundbreaking new diesel engine in 2020

Mazda is preparing to introduce its first series-produced electric car, but it's not sending the diesel engine to the automotive graveyard. The company remains committed to turbodiesel technology, and it will take its efficiency to the next level when it introduces a new range of engines in 2020. "We are sticking to diesel engines. In 2020, we have a new approach to diesel engines. We will show you how clean and very efficient diesel engines can be," pledged Christian Schultze, the head of research and development for Mazda's European division, in an interview with British magazine Autocar. He declined to provide specific details about the breakthrough that made a cleaner, more efficient diesel engine possible. Asked about how the engine compared to SkyActiv-X, the carmaker's newest and most innovative gasoline-powered engine, he pointed out "there are not so many differences between [gasoline] and diesel." His announcement falls in line with Mazda's belief that it's crucially important to consider real-world emissions over the life cycle of a car, not just local emissions. The company has realistically stated the internal combustion engine -- whether it burns gasoline or diesel -- will "continue to be the base power for 85 percent of all cars up until 2035." It might join forces with a 48-volt electrical system, or it might be part of a plug-in hybrid drivetrain, but it will still be around in 15 years. To that end, it's important to keep improving the technology, and not to prematurely pen its obituary.  "We hope governments wake up and see that electrification is one way but there are others, too," Schultze concluded, adding that SkyActiv-X is a step in the right direction. Mazda will release more details about its next turbodiesel engine in the coming months, but it's too early to tell whether it will available in the United States, where demand for oil-burning cars has hit rock bottom. As of 2019, the only diesel-powered Mazda sold in America is an upmarket variant of the CX-5 (pictured). Auto News Mazda Diesel Vehicles
