Will the Mazda2 be offered as a PHEV with a rotary engine range extender?

Every few months, it seems a rumor crops up about plans from Mazda to revive the rotary engine. Last November, its CEO said the only way another one could happen is if the project was profitable, and then a month later the automaker showed off the Mazda2 RE Range Extender with a 330cc Wankel engine mounted in the rear. Now, Australian auto site Motoring reports that the PHEV may actually make production in the next-gen Mazda2 sometime after it's initial launch.
Martin Benders, managing director of Mazda in Australia, spoke to Motoring about the company's future with hybrids and basically reiterated what the CEO said last year. The Japanese automaker only plans to offer electrified powertrains in places where they can sell in sufficient numbers to be profitable, like Japan.
Mazda has been playing with the rotary range-extender idea for years. In the RE prototype, the engine was exclusively used to charge the lithium-ion batteries when they were running low, and a 100-horsepower electric motor provided all of the propulsion. It gave the little hatch an estimated range of about 250 miles. The company reportedly took inspiration from its Skyactiv engines to make the Wankel have lower friction and a lighter weight.

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.

Mazda6 sees gains in ugly month for midsize sedans

Though June overall wasn't a terrible month for automaker sales, at least for the most part, it was pretty hideous for midsize family sedans. Basically every single model in the segment saw declining numbers including the Subaru Legacy, Nissan Altima, Ford Fusion, Volkswagen Passat, and even perennial volume sellers such as the Honda Accord and Toyota Camry. All of these cars are down in year-to-date numbers, too. But there's one bright spot, and it comes from Mazda. Mazda reports that the Mazda6 actually had a really good month. It sold 3,204 examples of the family sedan in June 2018, compared with 2,360 in June of last year. That's a nearly 36 percent increase month-over-month. It was also enough to bump Mazda6 sales for 2018 ahead of 2017's numbers through June. Those numbers also put the Mazda6 ahead of the Volkswagen Passat for June, and just 20 vehicles shy of the Subaru Legacy. Admittedly, these are still small numbers all around. In the same month, Honda sold over 26,000 Accords, and Toyota sold about 27,000 Camrys. Sales of Mazda's other vehicles also indicate that crossovers really are the new hotness. The CX-5 sold a whopping (relatively) 12,710 units. The CX-3 and CX-9 sold about 2,300 examples each, which is below both Mazda3 and Mazda6, but both crossovers gained more this month and over the year than both cars. Mazda3 is actually down this month and overall. All of this also seems to give some credence to Ford's decision to move away from traditional sedans. Still, for fans of more conventional cars, it's a bit heartening to see that more niche players can find some success with the design. We're also pleased to see such an excellent sedan recognized with actual buyers. Related Video: This content is hosted by a third party. To view it, please update your privacy preferences.
