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 returning to top-tier racing with diesel-powered prototype in USCC

Mazda has unveiled its latest challenger in the top flight of endurance racing, a diesel-powered prototype that will campaign the inaugural, 2014 Tudor United SportsCar Championship. The new Skyactiv-D-powered car will make its race debut at January's Rolex 24 at Daytona.
"This is the most significant step Mazda has taken towards returning to the global racing stage since our overall victory at Le Mans in 1991," said the director of Mazda Motorsports, John Doonan. That historic racecar, the rotary-powered 787B, has grown to become one of Mazda's many, well-known racers.
More recently, the Japanese brand has been making waves in the Grand-Am series, campaigning RX-8s and, most recently, running diesel-powered Mazda6 sedans in the GX-class. Mazda will campaign two factory-backed prototypes at Daytona. Driver lineups will be announced closer to race day.

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.
