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.

2021 Hyundai Elantra vs. compact sedans | How they compare on paper

Despite the rising popularity of crossovers, the sedan market remains packed and fiercely competitive. It looks like it will stay that way with the introduction of the strikingly redesigned 2021 Hyundai Elantra. And since Hyundai was kind enough to provide plenty of specifications on the new car, we figured we ought to see how it stacks up to some of the latest and greatest small sedans on the market. For this comparison we picked the two best-sellers, the Honda Civic and Toyota Corolla, one of the other recently redesigned sedans, the Nissan Sentra, and a perennial enthusiast favorite, the Mazda3. Below you'll find a chart with all the raw numbers for your perusal. Following that will be our usual break down and analysis of the numbers and any other noteworthy features not included in the chart. Performance and Fuel Economy While the design and chassis are all-new on the Elantra, the base powertrain isn't. It uses a version of the naturally aspirated 2.0-liter four-cylinder shared throughout the Hyundai and Kia line-ups, and it's again paired with a CVT. With 147 horsepower and 132 pound-feet of torque, it's the second least powerful entry for conventionally-powered sedans, only ahead of the sluggish 1.8-liter base engine in the Toyota Corolla. For those looking for a peppy small sedan, the Mazda3's naturally aspirated 2.5-liter has the most power and torque, even ahead of the turbocharged Honda Civic's 174 ponies. On the other hand, the Elantra, which Hyundai says will have better fuel economy than the outgoing model, should get at least 36 mpg combined, and probably better, making it the most efficient non-hybrid of this group. For the best blend of power and efficiency, the Civic is likely the way to go, as its turbo engine can return 36 mpg combined in lower trims. If you want a manual transmission in this body shape, only the Civic and Corolla offer it. A manual transmission is available on the Mazda3 hatchback, and the turbo Civic can also be had with a manual in hatchback or Si forms. A new powertrain for the Elantra is the hybrid. It's unique compared to other hybrids in that it's coupled to a six-speed dual-clutch transmission, rather than an electronically controlled CVT (which is not the same thing as a CVT) or something too complicated to describe in this sentence (the Honda Insight).

50 engineers kept the rotary alive at Mazda for 8 years

The Mazda RX-Vision concept is one of the standouts at this year's Tokyo Motor Show thanks to a drop-dead gorgeous design and a revival of the Wankel engine. The fact that the rotary is still in development at Mazda is thanks to a dedicated group of 50 engineers. According to Automotive News, their dream for the last eight years has been to bring this storied engine design back to the street. It won't be easy. Because of its design, the rotary suffers from poor fuel economy and high emissions. Making the challenge even harder, Mazda reportedly only gives them a small budget, but they continue to chip away at the problem. "These 50 engineers want to develop the rotary engine, therefore they joined Mazda," company research and development boss Kiyoshi Fujiwara told AN. "If I stop the rotary engine, probably they want to leave." For the Skyactiv-R under the RX-Vision's svelte hood, the team reportedly started from the 16X rotary project. Dating back to 2007, that 1.6-liter engine was supposed to improve torque and fuel economy thanks in part to direct injection. After additional development, insiders even suggested that the engineers might have finally solved the powerplant's issues. However, Mazda never put the mill into production, and the RX-8 remains the company's last Wankel-powered model to be offered in showrooms. "We have a dream that one day, this design with a rotary engine will achieve a level that customers will accept," CEO Masamichi Kogai said to AN. Mazda is quite clear that the RX-Vision might never go on sale without a suitable rotary. Although if it does see production, the coupe would likely use a stiffened version of the Miata's chassis, AN reports. Before anyone can place an order, these 50 determined engineers still have a lot of work ahead of them. Related Video:
