Mazda returns to rotary with RX-Vision Concept, crowd goes wild

Rotary! Forget everything for a second. Ignore the sleek styling, formed-by-wind sheetmetal, outrageously rear-drive proportions, and general ridiculousness of the sideview mirrors. And please be so kind as to ignore the poorly lit photos here – Mazda has a thing for drama. Concentrate instead on one fantastic phrase from the concept car press release: "next-generation Skyactiv-R rotary engine." The crowd here in Tokyo was downright frothing to get a look at the new concept car – hoping to catch a glimpse of the first evolutionary stage for a RX-9 sports car. The critical factor in that effort is of course the rotary engine. Mazda says that, while production of the powerplant is "on hold," the company has "never stopped research and development towards the rotary engine." The fact that the company has named the new engine gives us great hope that it exists in reality, and will be available for sale at some future date. The devil is in the details though, and there are precious few available at the Mazda stand. Other than a brief history lesson about Mazda's racing heritage, and fuzzy-vision talk about the future, we only have expectations to feed on. Oh, there's also a tiny press release, below. Related Video: HIROSHIMA, Japan—Mazda Motor Corporation unveiled the rotary-powered Mazda RX-VISION sports car concept at the Tokyo Motor Show*1 today. The rotary engine is a symbol of the company's "never-stop-challenging" spirit. RX-VISION represents a vision of the future that Mazda hopes to one day make into reality; a front-engine, rear-wheel drive sports car with exquisite, KODO design-based proportions only Mazda could envision, and powered by the next-generation SKYACTIV-R rotary engine. Rotary engines feature a unique construction, generating power through the rotational motion of a triangular rotor. Overcoming numerous technical difficulties, Mazda succeeded in commercializing the rotary engine, fitting it in the Cosmo Sport (known as Mazda 110S overseas) in 1967. As the only automaker to mass-produce the rotary engine, Mazda continued efforts to improve power output, fuel economy and durability, and in 1991 took overall victory at 24 Hours of Le Mans with a rotary engine-powered race car. Over the years, the rotary engine has come to symbolize Mazda's creativity and tireless endeavor in the face of difficult challenges. While mass production is currently on hold, Mazda has never stopped research and development efforts towards the rotary engine.

2016 Mazda6 and CX-5 see gentle price hike

Mazda has modestly updated the Mazda6 and CX-5 for the 2016 model year, and the company just announced revised pricing for the pair. The vehicles cost a little more now, but buyers also get additional features and an improved look. When it comes to the 2016 Mazda6, the already attractive sedan wears a revised look up front with more chrome and a redesigned cabin with a new instrument layout and seven-inch infotainment system on most models. Mechanically, things carry over with a 2.5-liter four-cylinder making 184 horsepower and 185 pound-feet and either a six-speed manual or automatic gearbox depending on trim. The base Sport trim with a six-speed manual gearbox costs $305 more than it did in 2015, and starts at $21,495*, plus an $820 destination charge on all models. Upgrading to the automatic gearbox at $22,995 also adds the revised infotainment system and reverse camera. Prices top out at $30,195 for the Grand Touring, which is $300 more than last year. All of the other versions see a $100 year-over-year increase. LED headlights are standard on the Grand Touring, but they can be added to the Touring through the Touring Technology package for $1,675. The 2016 CX-5 sees light exterior upgrades and similar interior improvements as the Mazda6, including the improved infotainment system for some trims. Pricing rings up for $250 more than last year, except the all-wheel drive Sport trim at just an extra $50. The cheapest CX-5 is the front-wheel Sport with a manual gearbox and 2.0-liter four-cylinder with 155 hp and 150 lb-ft, and it costs $21,795. All other models combine a 2.5-liter four-cylinder with 184 hp and 185 lb-ft with a six-speed automatic. Prices go all the way up to $29,470 for a CX-5 Grand Touring with all-wheel drive. There's a new i-Activesense package for the Grand Touring for $1,500, as well, that adds safety sensors and radar cruise control, but it can only be combined with the Grand Touring Technology Package for $1,505 with navigation and LED headlights. 2016 Mazda6 Pricing Announced IRVINE, Calif. (February 9, 2015) – Mazda North American Operations (MNAO) today announced pricing for its refreshed 2016 Mazda6 midsize sedan lineup. The 2016 Mazda6 is available in three trim levels – Sport, Touring and Grand Touring – and is equipped with the SKYACTIV-G 2.5-liter gasoline engine. There are a number of enhancements for 2016 including bold changes to the shape of the instrument panel and floor console giving the interior a fresh new look.

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.
