Mazda bringing electric car to the Tokyo Motor Show

In June this year, Mazda CEO Akira Marumoto told Automotive News Europe that "the first Mazda battery-electric vehicle will hit the market next year." Earlier this month, Mazda invited journalists to Oslo, Norway, to learn more about the automaker's EV plans and drive a prototype of the e-TPV powertrain, the letter designation standing for electric-Technology Prove-out Vehicle. Mazda had dressed the e-TPV production-intent powertrain under bodywork from the carmaker's new CX-30 compact crossover. Automotive News reports that Mazda will unveil its actual EV at the Tokyo Motor Show next month, which a Mazda spokesperson confirmed.     Mazda developed the powertrain in-house, engineered for buyers in dense urban environments. A 35.5-kWh lithium-ion battery powers a single electric motor wiith 141 horsepower and 195 pound-feet of torque. Range is said to be 200 kilometers (124 miles) on the city cycle, but that's likely on the Japanese or WLTP cycle that returns larger numbers than the U.S. EPA. The mechanical figures lie between the 28-kWh battery of the Hyundai Ioniq Electric and the 40-kWh battery of the standard Nissan Leaf. The EPA rates the less-powerful Ioniq for 124 miles of range, while the more powerful Leaf can go 150 miles. AN writes that Mazda's initial planned markets include Japan, China, and Europe where 124 miles is plenty for day trips. A version serving markets known for urban sprawl would employ a rotary engine range extender, a tech tidbit Mazda's spoken about regularly over the past year.   Iain Curry of Australian outlet Chasing Cars had good things to say about the e-TPV prototype he drove. Curry said the experimental car didn't offer strong regen braking and piped a mild four-cylinder soundtrack into the cabin to give drivers a connection to the ICE experience they're familiar with, but there's no word on whether the production vehicle will be set up the same way. Curry praised the handling, saying the e-TPV felt similar to a Mazda3 on the go and around corners. We'll get more concrete info next month in Japan. The show car in Tokyo will be a "brand-new model" on a new EV-specific platform, and don't be surprised by a compact crossover shape since the carmaker CEO said, "Our global crossover mix is currently about 60 percent."

Mazda Miata 25th anniversary display is roadster heaven on Earth

As part of the celebration of the 25th anniversary of the MX-5 Miata, Mazda has put together a rather large display at its New York Auto Show booth, showing off significant models from the diminutive roadsters history.
The display represents a healthy split of volume models, with cars 14, 15 and 17 sitting alongside cars 500,000 and 700,000. There are also more than a few concept cars in the offering, such as the Super20 Concept we drove a few years back, as well as older offerings, like the Club Racer concept from the 1989 Chicago Auto Show, the M-Speedster from the 1995 Chicago show and the M Coupe from the 1996 New York Auto Show.
We've put together a gallery of images of the historical Miata display, which you can view above. Take a look and then let us know which of Mazda's awesome roadsters is your favorite.

Mazda patents show rotary engine for range-extended EV

Two years ago, Mazda introduced a fascinating range-extended electric car called the Mazda2 RE Range-Extender. It took an electric Mazda2, and dropped in an itty-bitty 330cc rotary engine. It wasn't the rotary-powered sports car we had hoped for, but it seemed like a unique way to keep the quirky engine alive and kicking. But not long after the car's reveal, it seemed to disappear. Now the basic idea has resurfaced with a few modern updates in a couple of US patents. The first patent is pretty straightforward and describes a range-extended EV similar to the BMW i3. At the front is an electric motor driving the front wheels. At the back is an internal combustion engine that powers an electric generator. In the middle is a lithium-ion battery for storing and delivering electricity. It's the same set-up as that Mazda2. The second patent is for an engine start-and-stop system, but specifically for rotary engines. The system is designed to shut off a rotary engine when not needed, much as modern piston engines do. It also stops the rotor in a position that closes the intake port to ensure no fuel or exhaust emissions slip out through the intake tract. This is necessary since there are no valves in a rotary, and air and exhaust come through ports that are "opened" and "closed" by the rotor itself. The patent also describes the possibility of firing a spark plug after the fuel has been cut to eliminate any leftover fuel emissions. This system would theoretically improve a rotary engine's fuel economy and emissions significantly, which would be a boon as those are two of the rotary's major weaknesses. The rotary-engine patent also includes the same range-extended powertrain drawing as the first patent. It's there as a description of a possible application. And in such an application, where the rotary wouldn't have to run all the time, the system could take advantage of the rotary's inherent strengths. Weight can be kept low thanks to the engine's small dimensions, which should help in keeping the car sprightly and efficient. Rotaries are renowned for smoothness, too, so it shouldn't need too much refining and sound deadening, the latter of which adds more weight. The small size would also help with packaging, leaving more space for people, cargo, or possibly batteries. And since it has been patented, the company may be looking to bring the system to market.
