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's first-quarter profit slumps on weak sales in U.S. and China

TOKYO — Mazda reported a 79% drop in quarterly operating profit, falling significantly short of estimates, as it continues to struggle with declining U.S. and Chinese sales, while a strengthening yen also cut into its bottom line. Operating profit at JapanÂ’s No.5 automaker was 7.0 billion yen ($64 million) in the first quarter ended June, versus around 33 billion yen a year ago and less than half of an average forecast for 18.5 billion yen from analysts polled by Refinitiv. Mazda, however, reiterated its forecast for a 33% rise in operating profit to 110 billion yen in the year ending March. ThursdayÂ’s profit announcement marks MazdaÂ’s poorest first-quarter operating performance since the June 2012 quarter. The automaker has been struggling with falling demand for its cars over the past year or so, while it is also recovering from flood-related damage to its factories in Japan that led to a quarterly loss in the July quarter of 2018. The Nikkei business daily on Wednesday had reported that operating profit at the company would fall around 70% for the quarter due to lower sales in the United States. Mazda posted global sales of 353,000 units for the quarter, down 12% from a year ago. Its sales in the United States, its biggest market, fell 15% to 68,000 units, while in China, Mazda sold 54,000 vehicles, down 21% on the year. A trade war between the top two economies and slowing growth in China, the worldÂ’s biggest auto market, have prompted a broad-based sales downturn in the global auto sector. Automakers are grappling with easing demand for cars just as they must invest heavily in new technologies including electric cars, autonomous driving technologies and ride-sharing services to survive a major industry shift away from car ownership. Many of MazdaÂ’s rivals at home and abroad have been reporting disappointing quarterly results, with Nissan and Ford also announcing job cuts and possible plant closures earlier this month. The United States is a key source of revenue for Mazda, but it imports all its vehicles sold there, exposing it to a threatened hike in U.S. tariffs on imported cars from Japan. To limit its vulnerability to possible tariffs and currency fluctuations, Mazda is investing in a new plant in the U.S. state of Alabama, a joint project with Toyota.

Mazda and Lexus crowned with KBB 5-Year Cost To Own awards

We report on a lot of awards, some of which are given out based on more solid criteria than others. This one, the Kelley Blue Book 5-Year Cost to Own awards, seems like one that new car shoppers should pay attention to.
The cost of a car goes far beyond what you pay for the actual metal, leather and rubber at the point of purchase. Fuel, insurance, maintenance and repair costs, and the cost of fees from the state and financing will all weigh on your wallet while you own the car. That's not even taking into account the biggest cost: depreciation, or the amount of money you lose based on what your car is worth years from now versus the day you bought it.
KBB tracks these sorts of things, and they've compiled a list of winners for 2013 models. On the brand level, Mazda and Lexus earn the 5-Year Cost to Own award for having the lowest overall projected five-year totals (though, curiously, we note that Mazda and Lexus each had only one segment winner). There are lots of winners for all the various segments, so we'll just pick out a few surprising ones to share and you can view the rest here.
