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."

2019 Mazda CX-3 small crossover will start at $21,365

The figures are in for the 2019 Mazda CX-3 subcompact crossover, which will start at $21,365 when it arrives in showrooms later this month. That's $280 above the outgoing model, including a $975 destination and handling fee. Fuel economy figures are also now in from the EPA. When equipped with front-wheel drive, the 2019 CX-3 gets 29 miles per gallon in the city and 34 on the highway for a combined 31 mpg. The all-wheel-drive version is rated at 27 mpg in the city, 32 on the highway and 29 combined. Which are ... exactly the same figures as the outgoing version (so much for the promised fuel economy improvements). We detailed most of what's new about the 2019 version back in March at the New York Auto Show. Mostly, they're non-cosmetic changes: The carryover 2.0-liter Skyactiv four-cylinder picks up a couple more horsepower and pound-feet of torque for 148 total horsepower and 146 pound-feet of torque, joining a six-speed automatic transmission with manual-shift and sport modes. It also gets Mazda's G-Vectoring Control driving technology, a sportier, retuned suspension and improvements to make the driving experience quieter and more refined. Mazda says it's also added an electronic parking brake, which necessitated a redesign of the center console and armrest, adding storage space, and it redesigned the front seats and added a new rear armrest with built-in cupholders. Standard features include a new direct tire-pressure monitoring system and blind-spot monitoring with rear cross-traffic alert, two USB ports, a rearview camera, hands-free Bluetooth calling and audio pairing capability, and the 7-inch Mazda Connect full-color infotainment and diagnostic display, controllable via voice command or control knob. The new Sport i-ACTIVSENSE Package of safety technologies is available for an extra $1,100. It adds features including smart city braking support with pedestrian detection, lane departure warning, radar cruise control with stop-and-go function, LED headlights and LED combination tail lights. Other trim levels include Touring, which adds 18-inch wheels and keyless entry, and the top-level Grand Touring, which starts at $26,720 and $28,120 for front- and all-wheel-drive configurations, respectively. Grand Touring includes the Sport i-ACTIVSENSE Package, plus Parchment or black full-leather seating with high-gloss pleated piping and chrome accents on the front bumper and side sills, among other features.

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.
