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.

Mazda's product roadmap after Skyactiv-X: diesel, rotary, hybrids, even EVs

When we first heard that Mazda had cleared the major hurdles on gasoline compression ignition, and were just tidying up the details with clear production intent, the first kneejerk thought was: That's it for Mazda's consumer diesel. In particular, the Skyactiv-D that was intended for sale in the U.S., only to be delayed for years by various regulatory roadblocks and other issues that Mazda is frustratingly (but understandably) vague on. At least, it'd die out at some point down the road once Skyactiv-X was widely available. It turns out that's not the case at all. Mazda will adopt an approach that becomes more and more electrified and diverse the closer you get to 2035. But internal combustion will play a deep and central role up to that point, and probably beyond. Before we get to what those different powertrains, diesel and electrified, will look like down the road, let's stop and think about Mazda's philosophy. It couldn't be more different from the approach of most manufacturers that are currently producing BEVs and hybrids, which are heavily incentivized by both the automakers and the government, both state and local, depending on the locality. Even with all that cash on top of the hood, the market penetration of electrified vehicles is low. Mazda's too small to lose money paying people to drive EVs and hybrids. Its risky solution (which is plucky, but has had mixed results) is to simply improve the internal combustion engine. It's achieved the best fleet average fuel economy in the U.S. already, using a range of direct-injection gas engines that are mostly naturally aspirated. A few tiny nods to electrification have been introduced, like i-eLoop regenerative braking and the Demio EV (a Japanese-market, last-generation Mazda2 with a 20kWh battery that was tested with a tiny rotary engine range extender). But the focus is on combustion, not electricity. And that focus isn't going away anytime soon. Mazda believes that pure gasoline, gasoline hybrid, and gasoline PHEV vehicles will remain the vast majority of vehicle sold through 2035. At that point, Mazda forecasts, BEV and fuel cell vehicles should make up about 15 percent of the total of Mazda's lineup. The remaining 85 percent will utilize some form of internal combustion engine. Now, that includes hybrids and even a small number of CNG/LPG cars. And these are global numbers, as well. There may be even fewer fuel cell and CNG/LPG vehicles sold here than abroad.

Modded budget Mazda Miata takes on new Porsche Boxster in more challenges

Earlier this month, our friends across the pond at Auto Express released the first in a two-video series that would see them try and build up a second-generation Mazda MX-5 Miata that could best a standard Porsche Boxster around the track. While that first video detailed the mods to the MX-5 - a supercharger, some suspension upgrades and a new set of super-sticky rubber being chief among them - and set baseline lap times for the stock car, today, we have the results of the 5,000-pound ($8,200) upgrade job.
Of course, we aren't going to spoil those for you. You'll need to watch the full video, which recaps the upgrades before digging into a comparison of both straight-line-speed differences between the 2.7-liter Porsche Boxster and blown Miata, as well as their behavior and lap times on the track.
