Mazda CEO closes door on talk of RX sports car revival

Some rumors in the auto industry simply refuse to die. Over the last decade, a few of the strongest have focused on Japan. A few years ago, we could have explained away the constant whispering over a new Toyota Supra, Acura NSX or Mazda RX-7 as nostalgia for Japan's golden era of performance. Today, though is different.
We already have the Nissan GT-R, and, thanks to the Toyota FT-1 Concept, a Supra successor finally appears to be on the way. Acura will someday, allegedly, deliver on its promise to put the NSX on sale. So where does that leave the third member of the Japanese performance trio mentioned above? Well, um, it still isn't happening.
"We don't have that kind of vehicle in our future product plan," Mazda CEO Masamichi Kogai told Automotive News when asked about a successor to the rotary-powered RX line. "If you increase the number of segments, then the resources we can allocate to each will decline and that will prevent us from developing truly good products."

Mazda patent shows rotary placement in complex AWD hybrid layout

If we were playing alt-powertrain Bingo, a recent Mazda patent application filed in Japan would be one or two letters from victory. What's exciting about the patent, discovered by Japanese outlet T's Media via Motor Trend, is that while it makes a case for an internal combustion engine of any configuration, one of the drawings showing a rotary engine. The wild bit is that the whole powertrain comprises the ICE, a transaxle, two tiny in-wheel electric motors turning the front wheels, a third electric motor in the driveline, a capacitor, a lithium-ion battery, and three inverters. Motor Trend parsed the mechanics, and the way it reads, Doc Brown couldn't have done a better job. The rotary engine at the front turns the rear wheels, but not directly. Instead of a flywheel on back of the engine, the drawing shows a 25-kW electric motor and an inverter, then a driveshaft running to the transaxle. Along the axis of the transmission tunnel in a normal car, between the inverter and the transaxle, lies a 3.5-kWh battery running at 48 volts. MT writes that the electric motor can add its output to the ICE output to drive the rear wheels, or the e-motor can turn the rear axle on its own. Up front, two inverters and a double-layer capacitor join the ICE in the engine bay. The capacitor and tiny hub motors in the front wheels run at 120 volts, a higher voltage than the rest of the electrical system, so that the small in-wheel motors can generate the same torque as a larger motor running at a lower voltage. The AWD system acts on-demand. Given the signal, the capacitors discharge their energy to the wheel motors, and recover energy from braking. When the capacitors are at full charge, they send excess regen energy to the lithium-ion battery; conversely, the battery can recharge the capacitors when they're low and the front hub motors need power. The patent explains that the ICE works with the rear e-motor to drive the rear wheels at low speeds, the front motors called on to "generate an output only when a large output is required in the high vehicle speed range." The rather complicated system is focused on providing the benefits of a hybrid system and all-wheel drive, but at lower weight than one would expect. A rotary serves due to its compactness, but one of the drawings shows an engine with a V layout. Hub motors get dinged for adding unsprung weight, hence the small motors here.

2019 Mazda CX-9 improves its IIHS rating to Top Safety Pick +

The 2019 Mazda CX-9 three-row crossover has managed to improve its overall safety rating from the Insurance Institute for Highway Safety from an already respectable Top Safety Pick to the higher Top Safety Pick +. The area it needed to improve was in the headlight department, and now the crossover features a set of headlights that gets the highest "Good" rating, a prerequisite for the Top Safety Pick + award. The headlight improvement does have caveats. The top-rated headlights are only available on Signature and Grand Touring trims built after June 2019. Headlights on other trims and older models range from "Poor" to "Acceptable." All versions of the CX-9 have top scores in crash tests, though. Mazda's optional forward collision prevention system also earns full marks, stopping the crossover before hitting a car at speeds up to 25 mph. Child seat LATCH anchor access is rated as "Acceptable." Four other similarly sized and priced crossovers earn the Top Safety Pick + designation: the Hyundai Palisade, Hyundai Santa Fe, Subaru Ascent and Kia Telluride. And of those, only the Pallisade, Ascent and Telluride offer three rows of seating.
