Driving classic Mazdas to experience the weird and wonderful rotary's triumph

AUGSBURG, Germany — Everything weird and wonderful about Mazda's relationship with the Wankel rotary engine is embodied in the delightful 110S Cosmo Sport of 1967. Just shy of 1,200 were built and, for most of its life, it remained a Japanese curio. Driving one is a rare privilege, and yet here I am, leading a convoy of owners through Bavaria away from a private museum holding the most extensive collection of Mazdas outside of Japan. Created by local franchise holder Walter Frey, what started out as a business relationship in the 1970s has blossomed into a lifetime love affair. Whether the residents of Augsburg are quite so enamoured is another question. As I leave the museum I pass a sign proclaiming my entry into an "umwelt zone" for low-emissions vehicles. The oil-tinged plume of smoke in my wake rather makes a mockery and underlines one reason there are no rotary engines in the current Mazda product range. Created by a German but perfected by the Japanese, it seems appropriate to celebrate the association with the Wankel engine here. Mazda may have gone on to sell nearly 2 million rotary-engined cars to the world — the U.S. included — but 50 years ago it brought two Cosmos to the Nurburgring and entered them into the grueling Marathon de la Route as a proof of concept. After 84 hours of continuous running and a fourth-place overall finish, Mazda had demonstrated to the world a rotary could stay the distance. I have a slightly less grueling schedule but look forward to following the instructions to rev the hell out of the Cosmo to clear the smoke out of its system. Those following me will certainly be hoping this does the trick. A thirst for oil as well as gasoline isn't the only rotary trait. The two chambers of its motor displace 491 cc apiece, equivalent to about 2.0 liters in a regular reciprocating design. In this second-series car, it delivers around 128 horsepower, which drives the rear wheels through the transmission's five gears. There doesn't seem to be a whole lot of progress in any of them, truth be told, the characteristic lack of torque making for more noise than meaningful acceleration. It's a small car and weighs just more than 2,000 pounds, with a power-to-weight ratio not far off that of an original NA Miata. But it's one for carrying speed, not building it. The wood-rimmed Nardi wheel is one piece of luxury in an otherwise functional, vinyl-trimmed cabin, and through it the Cosmo has a nice blend of stability and agility.

Mazda rotary engine returns in 2020 as an EV range-extender

It's really, truly, finally happening, folks. The rotary engine is coming back. And just as the many rumors, patents, and even a Mazda2 prototype suggested, it will return as a range extender for an electric car. The news comes from an official announcement from Mazda itself. We won't have long to wait, either, as the rotary-supported EV is slated to go on sale in 2020. It will be one of two electric vehicles available, the other being fully electric. Mazda also mentions that the rotary powertrain is small enough to fit "shared packaging layouts." It's a possibility that these two vehicles are variations on the same model, similar to the Hyundai Ioniq and Honda Clarity. Mazda further notes that the rotary engine will also be able to run on liquified petroleum gas, citing the engine's ability to handle gaseous fuels. This has us wondering if Mazda will offer compatibility with other fuels at some point. Hydrogen could be a good choice for California, and Mazda has had a number of hydrogen-powered rotary-engine vehicles in the past. Propane compatibility could be popular in other regions. Mazda didn't say anything else specific about the vehicle besides highlighting the rotary engine's high power output with a small package and smooth operation. It also mentioned that the range-extended car could be used as a source of electricity when the power grid is down. We're sure to learn more as we near the car's 2020 launch date. Related Video:

Mazda's rotary-engine range extender could serve as an emergency generator

GENEVA — Mazda has some pretty exciting powertrain technology in the works, particularly its Skyactiv-X spark-controlled compression-ignition engine, but also the upcoming range-extended electric vehicle with a rotary engine. It offers the possibility of electric transportation with a distinctly Mazda way of getting electricity from gas when charging isn't an option. But we learned that Mazda has some other ideas for the rotary range-extender beyond transportation, and even beyond gasoline. In talking with Ichiro Hirose, Maza's managing executive officer for powertrain and vehicle development, product planning and cost innovation, we learned that the company is exploring the powertrain's potential as an emergency generator. Naturally if an engine is suitable for creating electricity in a car, it would be suitable to provide electricity to buildings or tools. Besides a rotary engine used as a standalone generator, Hirose said the company is investigating the potential for complete cars to be used as emergency generators, since they're already mobile. Gasoline wouldn't have to be the only potential fuel, either. Hirose said Mazda is looking at possibly running the engine on liquified petroleum gas, or LPG. We asked if hydrogen was also being considered, since Mazda has a history of hydrogen-powered rotary prototypes, even some that could run on hydrogen or gasoline, but Hirose said that's not being looked at right now.
