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.

Better as a coupe | 2017 Mazda MX-5 Miata RF First Drive

The sun can kill you. It'll also make you hot and sticky and smelly. It's a real nasty thing despite, you know, making virtually all life on Earth possible. Now, apparently, despite these risks, there are those who enjoy driving around in their car being slowly baked alive by our local star. It's insanity, really, and that's not even mentioning the indignities your hair suffers at the merciless force of the wind. So convertibles, then, who needs 'em? Just take the Mazda MX-5 Miata. Wonderful little car, barrels of fun, but wouldn't it be better off with 100 percent less sun? Besides keeping your dermatologist out of business, a solid roof would also lead to less wind noise, greater structural rigidity, and better safety for the vampire population. Nothing but Ws on the board. Alas, the 2017 Mazda MX-5 Miata RF is not the ideal solution to this perfectly sane line of reasoning. It is not the BMW M Coupe or Porsche Cayman of Miatas. It's more like the 911 Targa of Miatas, although since its rear window lowers, the most accurate analogy would be the Honda Civic del Sol of Miatas. Feel free to put that on a billboard. Admittedly, it's a pretty neat bit of engineering and design, and despite the incredibly flattering comparison above, it is accurate to describe its overall look and concept as unique. RF stands for "Retractable Fastback," which is an on-the-nose description. With the entire roof mechanism in place, it does indeed resemble a fastback in profile. From a rear-three-quarter view, that fastback is revealed instead to be buttress panels with a longer deck and a verticalish window placed between them. The Ferrari 575M Superamerica would be another point of reference, but the Miata RF is far better realized. It's particularly impressive how Mazda's designers managed to carefully reshape the Miata's rear quarters to fit and conceal the buttresses' cut line. From most angles, there's no indication that they're anything other than contiguous with the rest of the car. The little black panels that look like darkened windows at first glance are less successful, but they're also clearly necessary to create the desired buttress look and to conceal the roof mechanicals beyond. Ah yes, the compact mechanicals that make the fastback retractable and subject you to the sun's wrath.

Mazda planning 'aggressive' dealer shakeup

Mazda has set an ambitious goal of selling 400,000 units by the end of the 2015 Japanese fiscal year in March 2016, and to do that, it's going to need to take some aggressive action. That means that underperforming members of its 637-showroom strong dealer network are about to get the axe.
The purge won't just be limited to dealers that aren't performing, though. Mazda will seek to consolidate poorly located dealers and build new showrooms in better locations. It still isn't clear how many dealers are being targeted or at what point Mazda would end its cull.
This consolidation of dealers is all part of a one-two punch for the Japanese brand, that will also see increased marketing efforts in 35 key areas. Of those markets, Mazda is placing a special emphasis on New York and LA, although there's not much mention of what other regions are being looked at.
