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.

2017 Mazda Model Year Preview and Updates

Driving Matters, Mazda's marketing pitch, certainly resonates with enthusiasts, although may not be relevant with the increasing number of drivers engaged in texting while steering. Regardless of that disconnect, for drivers Mazda brings to market the long-awaited Miata coupe in Retractable Fastback (RF) form, pictured above. And for those wanting/needing a new crossover, Mazda redesigns its well-received CX-5. MAZDA3: Mazda's compact sedan and hatch receive a revised front end and tweaked rear. Inside, an upgraded interior with more storage space, improved sound proofing and materials round out the enhancements. On the road, all trim levels receive Mazda's G-Vectoring Control for enhanced handling and stability. MAZDA6: G-Vectoring Control is standard across all trims. Inside, improved sound insulation, new tech (including traffic sign recognition), and available Nappa leather takes an already upscale environment a few steps further into near-luxury. MAZDA MX-5 MIATA: The RF (Retractable Fastback) is the biggest news, as it serves as the answer to the long-awaited Miata coupe. Club models receive Blind Spot Monitoring and Cross-Traffic Alert – presumably helpful when the top is up. And the RF Launch Edition (1,000 examples) delivers a Nappa leather interior and hand-painted black top. The package is further embellished by Mazda's choice of Machine Gray metallic exterior color. MAZDA CX-3: Mazda's subcompact crossover receives minor updates. The Touring trim gets 18-inch alloy wheels, while the upmarket Grand Touring's available i-ACTIVSENSE is reduced in price. MAZDA CX-5: Mazda's compact crossover is all-new and on Mazda showrooms this spring as a 2017 model. Of particular interest to diesel fans is the introduction later in the year of Mazda's SKYACTIV-D 2.2 clean diesel, which arrives just in time for your Volkswagen buyback. MAZDA CX-9: Mazda's largest crossover is unchanged for 2017.
