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.

Fiat 124 caught entirely undisguised

Dear automakers, please continue making these kind of mistakes. Thanks to what we're guessing is some lax security, the all-new, Mazda MX-5 Miata-based Fiat 124 was spotted taking part in a photo shoot near Santa Barbara, CA. The images show what we'd consider a fairly simple rebadging job. The 124 gets new front and rear clips that not only harken back to the original 124 (not to mention other Fiat roadsters, like the Barchetta), but also serves to distance this droptop from the rest of the company's US range. The similarities between the 124 and the car it's based on are even more obvious in the cabin. This is an MX-5 interior with Fiat's big, red badge on the tiller. That means the same quality materials and knob-dial infotainment system that have been so well received in the Miata. It's under the hood, though, where the Fiat really differs from its Japanese cousin. According to our spy, the vehicle shown here features some kind of two-pedal setup – probably the six-speed Euro twin-clutch used in the 500L and Dodge Dart. Don't worry, though, a six-speed stick will also be on offer. Regardless of transmission, we can expect a 180-horsepower version of the 1.4-liter, turbocharged, four-cylinder offered in the 500 Abarth. And if that's not enough good news, a dedicated Abarth model will likely arrive after launch, which our spies claim will use the 1.75-liter turbo and DCT from the Alfa Romeo 4C. While this represents a good look at the new 124, we'll probably be waiting until the LA Auto Show in November for the official look. Stay tuned.

Future Classics, Acura Integra Type S and Cadillac Escalade-V | Autoblog Podcast #759

In this episode of the Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Associate Editor Byron Hurd. They jump right in with some news that Toyota may revive the Land Cruiser in the U.S., followed by rumors of a Nissan GT-R successor. From there, it's on to official confirmation of the Acura Integra Type S revival, followed by a partial rundown of Hagerty's 2023 Bull Market List. After that, it's time for some road test updates. Greg talks about his time in Autoblog's long-term BMW 330e PHEV and contrasts it with the 2023 Cadillac Escalade-V. Byron has been driving a Nissan Rogue, Mazda CX-30 and an Infiniti Q50 — serving as a perfect launch pad for a look back at 2022's best sport sedans. After that, it's a preview of Autoblog's 2022 Holiday Gift Guide.  Send us your questions for the Mailbag and Spend My Money at: Podcast@Autoblog.com.
