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.

2020 Mazda6 starts at $24,920, $200 more than 2019 model year

Mazda increased the price of all five trims of the 2020 Mazda6 by $200. The entry-level Mazda6 Sport starts at $24,000 before $920 destination charge ($965 in Alaska), for a total of $24,920. The only changes for next year are a new key fob likely copying the black and shiny metal unit from the Mazda3, and a new Signature badge likely in the form of the elemental "Sg" pulled from the CX-5 Signature model. The three Premium Paint choices carry over, with the same prices: Snowflake White Pearl Mica for $200, Machine Gray Metallic for $300, and Soul Red Crystal Metallic for $595. Prices of the other four trims run:  Mazda6 Touring $27,580 Mazda6 Grand Touring $30,620 Mazda6 Grand Touring Reserve $33,120 Mazda6 Signature $36,220 We're awaiting word on the arrival of all-wheel drive and the 2.2.-liter turbodiesel fitted to the CX-5. In the CX-5, that engine makes 168 horsepower and 290 pound-feet of torque. An AWD Mazda6 showed up in paperwork filed with the National Highway Traffic Safety Administration in January 2018, spy shots of a diesel-powered sedan followed in May that year, and Mazda mentioned the oil-burner again in April this year. For the time being, power for the 2020 Mazda6 will continue to be sent to the front axle through a six-speed automatic — Mazda eliminated the six-speed manual for the 2019 model year. The Sport and Touring trims come with a 2.5-liter four-cylinder that makes 187 hp and 186 lb-ft. The Grand Touring, Grand Touring Reserve and Signature raise that to a turbocharged 2.5-liter four-cylinder with 227 hp on 87 octane gas, or 250 hp on 93 octane, and 310 lb-ft.
