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.

Japanese students turning Mazda CX-5 into Dakar Rally-ready off-roader

Students at Japan's Nihon Automobile College (NATS) are transforming a first-generation Mazda CX-5 into a full-blown off-roader that looks ready to compete in the Dakar Rally. Named CX-Runner, the one-of-a-kind model will make its debut at the Tokyo Auto Salon opening its doors in January 2020. The Tokyo Auto Salon is the Japanese equivalent of the annual SEMA show, so anything goes under the bright lights. NATS students began the CX-Runner project with a used 2012 CX-5 and seemingly set out to leave as few original parts as possible. While the project isn't finished yet, a sketch released by the school suggests the crossover will receive wheel arch extensions, an external roll cage, a beefier suspension, and a shorter front bumper that increases the approach angle.  Photos published on the school's official Facebook page show the project is moving along nicely. The body extensions are made with a composite material that looks like Kevlar, and fitting the rear wheel arches required sealing the back doors, which is fine; the CX-Runner will be a two-seater. We don't know if students are planning to make changes to the CX-5's powertrain yet, but a thick skid plate will protect whatever is under the hood from expensive impacts with obstacles encountered off-road. nats-mazda-cx-runner-project-1 View 3 Photos The Tokyo Auto Salon will open its doors on January 10, so the students have time to finish the custom-made body kit, install the suspension, paint the CX-Runner, and fit the roll cage. They're not just doing this for fun, though. NATS began offering a customizing class in 1998, and building a tuner car is one of the requirements aspiring builders need to fulfill in order to graduate. With that in mind, it's no surprise that NATS will again have a big presence during the 2020 edition of the Tokyo Auto Salon. In addition to the CX-5 off-roader, its students are building six custom cars including a Nissan 370Z roadster wearing front and rear fascias sourced from a GT-R, a Toyota 2000GT-inspired convertible based on the Suzuki Cappuccino kei car from the 1990s, and a four-door, five-seater Toyota 86 built on Camry bones but powered by the coupe's flat-four engine.

Mazda CX-5, Mazda6 and Mazda3 could stall due to software glitch

Mazda is recalling 262,220 vehicles due to a software error that could cause the engine to unexpectedly stall out. The recall affects 2018-2019 CX-5 crossovers, 2018-2019 Mazda6 sedans and 2019 Mazda3 models.  According to NHTSA recall No. 19V497000, which was filed June 27, a programming issue in the powertrain control module (PCM) on select Mazda vehicles could cause the engine to shut down. More specifically, "the software controlling the hydraulic valve clearance adjuster may operate improperly when transitioning from cylinder deactivation to full cylinder activation modes." This could potentially cause the intake valve rocker arm to come out of position and hit something else in the engine. If this occurs, the engine could misfire, the engine could lose power, and the Malfunction Indicator Light would be triggered. The recall affects 143,004 2018 CX-5s, 81,236 2019 CX-5s, 18,295 2018 Mazda6s, 2,551 2019 Mazda6s, and 17,134 Mazda3s. Some cars from those model years received the improved software at the factory and won't be affected by the recall. Although the first report of a related issue was chronicled in January 31, 2018, no injuries tied to the problems have been reported. Mazda is expected to start its recall on or before August 26, 2019, and will reprogram the PCM with improved hydraulic valve adjustment control programming for free.
