Toyota, Mazda drop Takata as Mitsubishi, Subaru weigh options

It's not a very good time to be Takata right now. Fresh on the heels of longtime partner Honda ditching them, Toyota and Mazda have both come out and said they will not use the company's airbag inflators if they continue to rely on ammonium nitrate. Bloomberg reports that Subaru and Mitsubishi are also contemplating a divorce. "The inflator using ammonium nitrate produced by Takata will not be adopted by Toyota," President Akio Toyoda said during a briefing today. "What's most important above anything else is the safety and peace of mind of customers." Mazda echoed that position, simply saying it "will not use Takata airbag inflators which contain ammonium nitrate in our new cars." When you lose three huge OEM accounts in as many days, it's certainly going to have a deleterious effect on your fortunes. In Takata's case, that's meant a staggering 39-percent drop in their share price over the last three days. Yesterday alone, the company saw a 6.2-percent fall, Bloomberg reports. As the business publication reports, though, Takata isn't going down without a fight. The company is "considering some plans to survive," including a fundraising plan that will see it potentially offer up additional shares for sale. Still, at least one analyst doesn't see whatever company survives staying involved in the airbag inflator business. "I really don't see how they're going to be able to survive as an inflator manufacturer," Valient Market Research founder Scott Upham told Bloomberg. "When your major clients publicly come out and say that they're not going to use your products anymore, it makes this very difficult to sustain your business."

Mazda patents show rotary engine for range-extended EV

Two years ago, Mazda introduced a fascinating range-extended electric car called the Mazda2 RE Range-Extender. It took an electric Mazda2, and dropped in an itty-bitty 330cc rotary engine. It wasn't the rotary-powered sports car we had hoped for, but it seemed like a unique way to keep the quirky engine alive and kicking. But not long after the car's reveal, it seemed to disappear. Now the basic idea has resurfaced with a few modern updates in a couple of US patents. The first patent is pretty straightforward and describes a range-extended EV similar to the BMW i3. At the front is an electric motor driving the front wheels. At the back is an internal combustion engine that powers an electric generator. In the middle is a lithium-ion battery for storing and delivering electricity. It's the same set-up as that Mazda2. The second patent is for an engine start-and-stop system, but specifically for rotary engines. The system is designed to shut off a rotary engine when not needed, much as modern piston engines do. It also stops the rotor in a position that closes the intake port to ensure no fuel or exhaust emissions slip out through the intake tract. This is necessary since there are no valves in a rotary, and air and exhaust come through ports that are "opened" and "closed" by the rotor itself. The patent also describes the possibility of firing a spark plug after the fuel has been cut to eliminate any leftover fuel emissions. This system would theoretically improve a rotary engine's fuel economy and emissions significantly, which would be a boon as those are two of the rotary's major weaknesses. The rotary-engine patent also includes the same range-extended powertrain drawing as the first patent. It's there as a description of a possible application. And in such an application, where the rotary wouldn't have to run all the time, the system could take advantage of the rotary's inherent strengths. Weight can be kept low thanks to the engine's small dimensions, which should help in keeping the car sprightly and efficient. Rotaries are renowned for smoothness, too, so it shouldn't need too much refining and sound deadening, the latter of which adds more weight. The small size would also help with packaging, leaving more space for people, cargo, or possibly batteries. And since it has been patented, the company may be looking to bring the system to market.

2018 Mazda6 gets more power, efficiency to go with updated looks

The 2018 Mazda Mazda6 will debut at the L.A. Auto Show later this month, and the company released teaser images of the exterior and interior Wednesday – both of which tell us a lot about the new car. Mazda also said the sedan will have more efficient and more powerful engines. Starting with the visuals, the car doesn't look extraordinarily different from the current model, but there are notable changes. Up front, the Mazda6 now has a deeper-set grille with a 3D mesh instead of slats. The chrome strip that wraps around the lower part of the grille extends across the width of the headlights, too. Both of these cues are pulled from the Mazda CX-5. From what we can tell in the image, it looks like most of the sheetmetal along the sides and top are roughly the same as the current model. The interior also isn't a major departure from the current car, but the changes do make it cleaner and more elegant. All of the air vents sit along one slender plane that stretches across the interior. It leaves the top of the dash uncluttered and makes the vents look like a more integrated part of the design. Below the vent strip is another line of what appears to be vinyl or leather trim, and below that are the climate controls. The updated looks are accompanied by significant mechanical upgrades. While the current model offers just one engine, a naturally aspirated 2.5-liter four-cylinder, the new car will have two options. The first is again a naturally aspirated 2.5-liter engine, but it now has cylinder deactivation, allowing it to run on just two cylinders at times. For those who prefer power to efficiency, the Mazda6 will also be available with the turbocharged 2.5-liter four-cylinder from the CX-9 crossover. In that application, it makes 250 horsepower and 310 pound-feet of torque. The full reveal of the car happens on November 29 at the L.A. Auto Show. Be sure to check back then for more photos of and details about the car. Related Video: Image Credit: Mazda LA Auto Show Mazda Sedan
