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.

Mazda teases CX-4 for the Beijing Motor Show

Mazda will unveil the CX-4 crossover at the Beijing Motor Show in late April, and the company's single teaser image (above) suggests the CUV might borrow styling cues from the larger Koeru concept. Mazda kept details about the CX-4 light for now but says in the announcement, "this is a new type of crossover SUV designed to help customers live more creative lives." The teaser photo offers some hints about the design. For example, the rear pillar comes to a point and features chrome accents, which are elements from the Koeru and production CX-9. The arching roof rail suggests a coupe-like shape because it arcs downward to the hatchback. The name also hints that this model slots between the CX-3 and CX-5 in the lineup, but the CX-4 appears to prioritize style over utility. We can't wait to get a better look because this picture doesn't offer much detail. The company will also show versions of the Mazda3 and Mazda6 for the China Touring Car Championship at the Beijing show.

Goodbye Zoom-Zoom, Driving Matters is Mazda's new slogan [w/video]

Timed with the launch of the 2016 MX-5 Miata, Mazda is now changing gears with its advertising strategy in the US by launching a whole new slogan. The Japanese brand's latest marketing motto takes a much more direct approach than Zoom-Zoom by simply saying Driving Matters. The two-word phrase is meant to make customers believe that a good time behind the wheel can improve their lives. Driving Matters is also supposed to say something about how Mazda engineers vehicles. "Whether it's for safety purposes or for maintaining our 'fun to drive' nature, it all comes down to the fact that driving matters to our customers and it matters to us." Russell Wager, vice president of marketing at Mazda North American Operations, said in the announcement of the new campaign. However, Zoom-Zoom isn't entirely dead, and the words still appear in small print in some of these spots. According to Wager in an interview with Automotive News, the old slogan isn't necessarily understandable to some focus groups. "I'll ask them to explain to me what 'Zoom Zoom' means, and I'll get 6 or 7 different answers. That's what Driving Matters is supposed to address. It's supposed to solidify what 'Zoom Zoom' means to people," he said. So far, the company has released several examples of the campaign to highlight the Miata and Mazda6. At the same time, Mazda is launching a new commercial (embedded below) called A Driver's Life that showcases many of its models but puts a big emphasis on the MX-5.

Mazda Launches All-New Advertising Campaign, "Driving Matters" - New Campaign Communicates How the Joy of Driving Can Enhance Your Life - IRVINE, Calif. (May 21, 2015) –The Oxford Dictionary defines "driving" as, "operating and controlling the direction and speed of a motor vehicle." Mazda believes that driving is more than a definition. Driving is an experience that can enhance your life. To better illustrate how every Mazda vehicle embodies why "Driving Matters," today Mazda North American Operations (MNAO) is rolling out a new advertising campaign. Driving Matters is an evolution of the Game Changers campaign. With Game Changers, Mazda succeeded in increasing consumer awareness of the functional attributes of our vehicles. Driving Matters will extend the message by creating an emotional connection to the brand.
