Mazda patents show rotary engine for range-extended EV
Fri, Mar 17 2017Two 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.
Question of the Day: What's the most irritating car name?
Wed, Mar 9 2016You hear a lot about how the Chevrolet Nova was a sales flop in Mexico because "No va" means "it doesn't go" in Spanish; in fact, the Nova sold pretty well south of the border, and in any case most Spanish-speakers know that "Nova" means "new" in Latin and Portuguese. However, General Motors doesn't deserve to be let off the hook for bad car names, because the Oldsmobile Achieva— no doubt inspired by the excruciating "coffee achievers" ads of the 1980s— scrapes the biggest fingernails down the screechiest chalkboard in the US-market car-name world. That is, unless you think Daihatsu's incomprehensible choice of Charade was worse. Meanwhile, Japanese car buyers could get machines with cool names like Mazda Bongo Friendee or Honda Life Dunk. It's just not fair! So, what car name drives you the craziest? Related Video: Auto News Design/Style Chevrolet Honda Mazda Daihatsu Automotive History questions car names
2019 Mazda MX-5 Miata may be getting 181 hp
Thu, Mar 1 2018Even though the current 2018 Mazda MX-5 Miata makes only 155 horsepower, our experience has shown that it's more than enough fun with its modest output. Still, if Mazda were to offer more, we wouldn't turn it down, and it appears that's exactly what will happen for the 2019 Mazda MX-5 Miata. Road & Track dug up a VIN filing from Mazda to NHTSA with information about the Miata for that model year. On one of the pages, it states that the 2019 Miata will have a 2.0-liter four-cylinder making 181 net brake horsepower. That's a pretty big jump from 155 horsepower, nearly matching the larger 2.5-liter engine in the Mazda3 and Mazda6. It's also close in power to the estimates for the Skyactiv-X spark-controlled compression-ignition engine. But, based on what a journalist on Twitter posted, the 2019 Miata will continue to use a version of the existing spark-ignition Skyactiv-G engine. Apparently it will have a new cylinder head, be able to rev higher, and make more horsepower, though he didn't say how much more. This content is hosted by a third party.

We've reached out to Mazda for comment on this discovery, and, like with most car companies, wouldn't give comment since the topic regards a future product. If it does turn out that Mazda won't up the horsepower for 2019, the good news is that the aftermarket has speed demons covered. Flyin' Miata offers a package that includes camshafts, exhaust and a tune that will bring it up to about 200 hp. There's a supercharger kit from Edelbrock that will provide similar power, but without the need for digging into the engine. Flyin' Miata also offers a turbocharger kit that can bring the Miata up to nearly 250 hp, and if you're really speed-crazed, the company can swap in a Chevy LS V8 with more than 500 hp. Or, you know, you could just be happy with 155. Related Video: Featured Gallery 2016 Mazda MX-5 Miata Club View 32 Photos News Source: Road & Track, Twitter Mazda Convertible Coupe Performance
