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.

eBay Find of the Day: 1990 Mazda Miata with just 27 original miles

Some cars have low mileage, and others have close to no miles at all. This 1990 Mazda Miata, currently listed on eBay Motors and located in Kingman, Arizona, falls into the latter category with only 27 miles on the odometer, according to the seller. But we have to wonder: how did one of the best-driving, most influential sports cars of the past two decades sit without being driven for 24 years? Consider it the seller's loss on this one.
The seller says he bought the car with 20 miles on it, and explains 6.9 miles were added when the car was towed home on a car dolly. It was never registered. Furthermore, the seller says the car didn't come with a set of keys, so he had to have a set made. Though the paint is clean and shiny, the Miata didn't escape minor cosmetic damage over the years, with scratches on the hood, the trunk and the factory hardtop that is included with the car. The front, right fender has a small dent as well, which can be seen in a picture. The seller says the car was stored in a building with windows, so the paint is faded a bit in some places. It's missing its antenna and the battery, and the only non-original parts on the car are the windshield wipers. The clear-title car comes with all paperwork, according to the seller, but, besides the owners manual, he didn't specify what other documentation would be included.
With bidding currently at $10,300 and the reserve not met, this Miata definitely isn't the deal of the century, and we have to question where the value is in this one. The way we see it, it's hard to justify the money if it can't be driven as-is (come on, no battery?), has questionable history, isn't rare and sat in storage for its whole existence. The "weather cracked" tires are probably just the first rubber parts on the car that need to be replaced before it can be driven, but at least the spark plugs were removed and the cylinders were filled with Marvel Mystery Oil prior to storage, which helps to prevent rust and corrosion from forming in the engine.

Mazda G-Vectoring Control makes driving better without you knowing

Mazda has just spent eight years developing a new technology that will make its new cars a lot more fun to drive, even if you have absolutely no idea that it's working. And subtlety's the point, Mazda engineers told us at a press event at Mazda Raceway Laguna Seca. In fact, the effects of what they've dubbed G-Vectoring Control are so fine that the marketing and PR teams are at a loss for how to do their jobs with it. "The engineers have done their work," said Mazda Director of Communications Jeremy Barnes, "But how do we get the message across?" The basic premise is this: G-Vectoring activates only when the car's on-board computer reads simultaneous steering and throttle input. The data — including throttle position, steering angle, and, crucially, how quickly you're adjusting the steering angle — are then funneled through an algorithm to reduce engine torque, which transfers vehicle weight, adding more grip to the wheels that need it. The system will appear first on 2017 Mazda6 sedans arriving in showrooms later this year, followed by the 2017 Mazda3. Actually, "subtle" does not even begin to describe the effect. G-Vectoring Control can detect as much as one tenth of one degree of steering angle, and changes the cornering forces only 0.1 to 0.5 g as a result. "That's less than the human body can feel," explained Vehicle Development Engineer Dave Coleman. In practice, G-Vectoring reduces the steering angle at turn-in, as well as the rate at which one turns the wheel. To demonstrate, Director of R&D Kelvin Hiraishi rode shotgun with us in a specially equipped Mazda6 that allowed him to turn G-Vectoring on or off at the push of a button (production cars will always have it on). Hiraishi had us drive a number of courses, including Mazda Raceway Laguna Seca itself, while an engineer measured our steering inputs with a laptop Matrix'd into the car's electronic brain. I drove the same course several times with the same car in the same conditions, with cruise control locked and the system turned on or off. Lo and behold, with G-Vectoring activated, the engineer's output graph showed that my steering inputs were indeed reduced ever so slightly. There were two times that G-Vectoring was markedly noticeable. The first on a turn with a minor banking toward the outside, and the second was during cornering over an artificially wet section of the course — in other words, when the car was at the limits of adhesion.
