Toyota, Mazda form electric car technology venture

TOKYO — Toyota has established a new venture to develop electric vehicle technology with partner Mazda, seeking to catch up with rivals in an increasingly frenetic race to produce more battery-powered cars. Policymakers in key markets like China are pushing a shift to electric cars over the next two to three decades, while relatively new rival Tesla is gaining momentum and diesel cars are going through the fallout of the Volkswagen diesel scandal, pressuring traditional automakers to crank up plans for fully electric vehicles (EVs). At the same time, declining battery costs are enabling more power to be packed into cars, making an electric car future easier to imagine. Toyota said in a statement the new company will develop technology for a range of electric cars, including mini vehicles, passenger cars, SUVs and light trucks. Toyota will take a 90 percent stake in the joint venture, called EV Common Architecture Spirit Co Ltd, while Mazda and Denso Corp, Toyota's biggest supplier, will each take 5 percent. The plans build on a partnership announced in August when Japan's biggest automaker agreed to take a 5 percent stake in Mazda and two said they would jointly develop affordable electric vehicle technologies. Although Toyota is providing most of the financial firepower and existing EV know-how, Mazda's engineers have gained the admiration of the industry with breakthrough technologies such as its compression ignition engine announced last month. Shares in Mazda surged to end the day 3 percent higher, while those in Denso rose 1.8 percent. Toyota shares were flat. Both automakers are somewhat behind rivals, with neither having a fully electric passenger car on the market yet. After years of focusing on bringing hydrogen fuel cell vehicles to the market, Toyota last year set up a division to develop electric cars which is led by President Akio Toyoda, and said it plans to introduce EVs in China in the coming years. Toyota has also announced it will bring a game-changing solid-state EV battery to market by 2022. That division would continue as a separate entity from the new joint venture, a Toyota spokeswoman said, while adding that the two teams would co-operate on technology development. Mazda has an R&D budget a fraction of Toyota's, which has made it difficult to develop electric cars on its own. Even so, it has said it plans to launch EVs in 2020.

Confirmed: Mazda Miata gets more power, higher redline, telescoping wheel

Our friend over at Road & Track, Bozi Tatarevic, has a keen nose for stuff just like today's Miata news, and he spotted an article by the Japanese car magazine Car Watch that details Mazda's upcoming updates. Car Watch actually got to drive the car, too. There's a lot to go through, but the highlight has to be confirmation of what we told you earlier this year about a significant power bump: The Miata will indeed get an increase of 26 horsepower, from 155 to 181. But the power's not the whole story. Mazda has increased the redline from 6,800 RPM to 7,500. It's not clear at this point where torque and power peaks are in the rev range, or how these changes affect low-speed drivability, but more revs are almost always a good thing and aren't likely to detract from the roadster's fundamental goodness. Car Watch reports that lighter pistons and connecting rods are fitted to help reduce rotational mass in the 2.0-liter inline-four. Some valvetrain changes were needed to support the higher redline, mainly stiffer valvesprings to prevent valve float. Mazda also changed the shape of the valves and optimized the intake ports to breathe better at higher RPM. The inner diameter of the exhaust ports were increased to flow better through a new muffler better tuned to the engine's new operating range. This confirms and gives a little more detail to what we reported earlier based on a leaked document from Mazda Canada. Car Watch also confirms that the revised Miata will get a low-inertia dual-mass flywheel, which should help absorb some vibration, noise and harshness from the higher-revving engine without losing too much of the directness that a single-mass flywheel provides. Mazda usually gets stuff like this right, so while we won't know until we get a chance to drive it whether the DMF feels "right," we're not too worried about it. There's also a telescopic steering wheel, a first in any Miata, which has a range of about 1.1 inches. That doesn't sound like much, but it should help folks with longer legs reach the wheel without having to crank the seat forward. Interestingly, Car Watch reports that the telescoping wheel was opposed by some in the company seeking to save every fraction of an ounce of weight, and to get it through, the company apparently had to change some of the material in the upper steering column from steel to aluminum to satisfy the weight-conscious. Little details like these are fantastic.

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.
