Mazda engineer wants new rotary to be turbocharged

Hope springs eternal for Mazda to revive the high-revving Wankel engine for a new sports car, and the company keeps feeding that thirst with hints that it could happen. To make the possibility even more tantalizing, Mazda drivetrain and powertrain assistant manager Tetsushi Marutani tells Motoring that he wants the updated mill to pack a turbocharger. "Personally, I think that a rotary with some turbo or compressor would be good," Marutani said to Motoring. "Because a rotary, in my opinion, they require more [torque at] low speed, low down torque. So if we have some small compressor or turbo it would help." Mazda hasn't sold a rotary-powered model since the RX-8 and hasn't had a turbocharged one since the third-generation RX-7. However, the recent RX-Vision concept (above) at least hinted at a possible Wankel revival, and Mazda officials confirmed that its engineers continued to develop the engine since the RX-8's demise. The RX-Vision used a next-gen rotary called the Skyactiv-R, but Mazda didn't officially confirm any details about it. Rumors suggested the engine had a two-rotor layout with a total displacement of 1.6 liters. A two-stage electric turbo and hybrid powertrain would allegedly boost the total output of around 450 horsepower. The electric assistance could also counter the Wankel's lack of torque at low revs and poor fuel economy. Those rumored specs sound fantastic, but we still take the rotary's return with a grain of salt. Mazda CEO Masamichi Kogai is adamant that it's not worth the company's limited resources to develop a niche sports coupe instead of better selling vehicles. Related Video:

Mazda CEO says rotary not viable, so don't look for a new one

We have some very sad news to report, rotor-heads fans: Don't expect a new rotary-powered vehicle anytime soon. This comes straight from Masamichi Kogai, the CEO of Mazda, which is the only company to ever market a commercially successful rotary-powered automobile in the world. The issue, as it has pretty much always been, is environmental.
While the Wankel rotary engine does indeed make a lot of power in a small, lightweight package, it does so while burning lots of fuel and emitting lots of noxious gases into the atmosphere, at least when running on gasoline. And that means the rotary engine will likely only ever be able to power niche vehicles. And that, in turn, means that it is very difficult to turn a profit on vehicles with rotary engines, particularly for a small automaker like Mazda.
"It has to be a viable commercial proposition. If we are going to adopt it, it has to be a product that can generate at least sales of 100,000 units a year. We have to be able to achieve a profit," said Kogai in an interview with Automotive News. Mazda sold 56,203 RX-7 models in the United States (the automaker's biggest market) in 1986. Sales of the RX-8 peaked in 2004, its first full year on the market, with just 23,690 units.

2015 Mazda2 spotted in Japanese magazine

The styling changes at Mazda are proceeding at a fairly quick tempo. The CX-5 was unveiled, followed by a refreshed CX-9, the excellent Mazda6, and most recently a new Mazda3. This all happened over the course of less than two years, which in the auto industry is like a long week.
Now the Mazda2 is getting its revamp. Thanks to a magazine scan from Japan, we now have our first look at the new sub-compact, called the Demio, in its home market. Mazda's familial front end has been fitted, and it doesn't look quite as suited to the smaller car. Lacking the long-hood look of the Mazda3 and Mazda6, the new styling looks overly rounded, almost bulbous from our angle. It's still attractive, but the shape is kind of off-putting compared to the chiseled faces of the 2's big brothers. We'll concede that the folded magazine page may have something to do with it, however.
The next-generation 2 should adhere to Mazda's Skyactiv philosophy, which means we can expect a highly efficient four-cylinder engine, although it's impossible to say if Mazda will do away with its smallest offering's one-engine strategy. Considering the Mazda2 will be riding on a shortened version of the CX-5's platform, we'd expect some degree of mechanical parts sharing, regardless of how much the larger platform needs trimmed. Perhaps a detuned version of the 2.0-liter, Skyactiv four-cylinder could be under the 2's hood?
