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.

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.

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 Review & Buying Guide | Still at the top

The 2020 Mazda6 should be on anybody’s sedan shortlist. ItÂ’s modern and attractive both inside and out. The ride and handling balance is unmatched by anything short of the 2020 Honda Accord, and itÂ’s priced well alongside all of its tough competition. An Accord is still the only one in this segment to offer a manual transmission for enthusiasts who care to shift themselves, but the Mazda6 with the 2.5-liter turbocharged four-cylinder is still plenty of fun with its smart-shifting six-speed auto. Mazda has also succeeded in putting together a luxurious interior — highlighted by the Signature trim — that outdoes the more pedestrian interiors found in other pricey mid-size sedans. Tons of work was put into the Mazda6 to make it more refined and premium, and itÂ’s worked. Downsides are few in number, but if the Mazda6 suffers anywhere, itÂ’s in the infotainment and utility departments. The software Mazda uses is old and antiquated compared to its new system in the Mazda3 and CX-30, as well as those in the Accord, Hyundai Sonata and others. The trunk is also smaller than most in this segment. Those may be deal breakers for some, but people who value an engaging driving experience will appreciate it for its sharp steering and agile chassis, and those who could care less will still love it for the refinement and comfort. WhatÂ’s new for 2020? There isnÂ’t much new for the 2020 Mazda6 this year. Mazda says itÂ’s switched to the key fob design used on the Mazda3 and CX-30, and thereÂ’s also a new “Signature” badge for the top trim. Besides that, the car carries over unchanged from 2019. 2020 Mazda6 Signature View 57 Photos WhatÂ’s the interior and in-car technology like? The 2020 Mazda6Â’s interior is simple and beautiful. Mazda has upped its interior quality game beyond the competition, and itÂ’s accomplished this without pricing the sedan out of the ballpark. Comfortable chairs make long rides a breeze as does the hushed cabin noise. From lower trims on up, the cabin looks and feels of a high quality. Even the basic entry-level Sport trim has an excellent interior that goes above the more basic furnishings of competitors, while on the other end of the spectrum, the Signature boasts rich suede-like cloth and beautiful Sen wood to create an environment encroaching on the luxury segment. However, MazdaÂ’s infotainment system is way behind compared to others in the segment.
