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.

Kiwi seniors accidentally lock themselves in Mazda3 for 13 hours, nearly die

It's an over-played trope that senior citizens are bad with technology. Its regular use as a comedic device, though, overshadows a more dire circumstance that comes when elderly citizens are paired with gizmos and gadgets they don't fully understand. A couple from New Zealand spent the night in their new, smart-key-equipped Mazda3 after thinking they'd locked themselves in, in what The Otago Daily Times called "a series of 'Murphy's Law' events." The two thought the car wouldn't function without the key fob, which had accidentally been left outside of the car, along with the owner's manual. That, along with the combination of stress, darkness and a lack of overall information about the car nearly killed Mollieanne and Brian Smith. After thinking they'd become trapped, the Smiths, 65 and 68, respectively, tried honking the horn to alert neighbors – it was Guy Fawkes Night, so the sound was drowned out by fireworks – and even took the Mazda's jack to a window in their attempt to escape. When they were discovered and freed 13 hours later, Mrs. Smith was unconscious and Mr. Smith was having trouble breathing, with emergency crews telling the couple another half hour in the car would have killed them. Mr. Smith later told The Otago Daily Times he was "very methodical," but couldn't figure out how to unlock the car. "Once I found out how simple it was to unlock it I kicked myself that I did not find the way out," the 68-year-old told The Times. "I had this mind-set that I did not have the transponder [so I could not get out]." Mazda New Zealand pointed out that is not the case. "It's not a design flaw with the car," Mazda New Zealand General Manager Glenn Harris told The Times. "What we have said to the [dealership] network is, with new technologies, don't forget to show customers how to use them in their entirety [and] how to override them. There is always a manual process to override them."

2014 Mazda6 to start at $20,880*

We got our very first taste of the impressive 2014 Mazda6 back in October, and had more than a few good things to say about the midsizer. One piece of information that was conspicuous by its absence, however, was a sticker price.
Now, with zero pomp and circumstance (not even a press release as of this writing), Mazda has dropped what looks to be official pricing for the 6 on its consumer website.
$20,880 is the asking price for the base Mazda6 Sport with a manual transmission (plus $795 worth of destination charges, for a total of $21,675). Alaska residents will need to cough up $840 for destination. The loaded-up Mazda6 Grand Touring shown on the site will set you back a total of $30,290 (MSRP of $29,495), but it isn't clear if that's the starting price of the Grand Touring trim. Mazda is taking orders for the new 6 right now, and the cars will be available on January 2, 2013.
