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.

This California rally is vintage Japanese car heaven

What's so good about the future? This is what I was thinking when some folks at Mazda invited me and a handful of other journalists to join them on the second-annual Touge California. It's a rally for classic Japanese cars that covers a huge chunk of Southern California's twistier roads, where fans get to test their beloved machines. Oh, and it attracts swarms of admirers with cameras. "It is not a race. It is a vintage touring rally," said Ben Hsu, editor in chief of Japanese Nostalgic Car, and one of the coordinators of the event. "In Japan, touge most definitely refers to racing, whether timed, in touge battles, or drifting antics. Touge California was created to give drivers of Japanese classics a taste, as close as possible, of the types of roads their cars were forged on." Touge California was created to give drivers of Japanese classics a taste, as close as possible, of the types of roads their cars were forged on. We started the day on a mundane stop-and-go freeway drive from Mazda's Irvine headquarters to Escondido, me riding shotgun with my journalist co-driver in a 2016 Miata. But Mazda also brought along three heritage products on this trip – a 1985 RX-7 GSL-SE, a 1978 GLC three-door hatchback, and a 1975 REPU (rotary engined pickup) – serving as reminders of the company's history in the U.S. The group of Mazdas was joined in Escondido by many more Mazdas. And Toyotas, Hondas, Datsuns – so many 240Zs – and the odd Subaru and Mitsubishi. In total, 28 cars were at the start line. "We doubled the field this year, and made the route longer – 200 versus 120 miles," Hsu said. "We separated the cars into two run groups based on speed and a mix of makes and models." I spent the first part of the rally in the Mazda pickup to get a taste of rotary power. It was my first experience behind the wheel of a Wankel-powered vehicle, my first time driving a small Japanese truck from the '70s, and my God that thing has a lot of power. I had a few scares when I had to stand on the brakes, and I found the shift throw's immense length disconcerting – it felt like third gear engaged somewhere in front of the dashboard, with fourth somewhere in the bed. The truck was a great introduction to the rotary, however, and to '70s Japanese cars. Especially in Southern California, old Japanese cars aren't as novel to casual observers as they might be in other parts of the country.

Watch what happens inside a rotary engine

Since it looks like Mazda may very well revive the Wankel rotary engine as a range extender for electric cars, there's no better time to become reacquainted with the quirky internal-combustion engine. And there's hardly a better way to become reacquainted than by peering into a running rotary engine, which you can do with the video above. The video comes to us from the YouTube channel Warped Perception. The channel has already shown what happens inside a conventional internal-combustion piston engine by putting a clear cylinder head on top of a flathead engine. This new video shows off the rotary engine by adding a clear side to a tiny model-airplane engine, something that we weren't aware existed and are glad to know about now. Despite the tiny size, the engine is functionally almost exactly like the bigger versions you'll find in Mazdas from about 1967 to 2012. It has intake and exhaust ports on the edges of the rotor housing, and the triangular rotor swings about in a peanut-shaped housing. For maximum effect, jump to right around the 7:40 timestamp. This is the point at which a bit of acetylene is added to the air-fuel mix for a brighter flame. It's at this point that you can really see when the mixture combusts and how the pressure of the flame pushes the rotor to produce rotational motion. Each stage of the video does slow things down to make everything as clear as possible. Even if you already knew how rotary engines worked, it's still fascinating to watch, first because it's something you don't get to see usually, and also because of the engine's elegant simplicity.
