Long Road Racing will build you the Miata that Mazda won't

One of the frustrating things about new cars today is that many features are exclusive to this trim level, or that package. Even the enthusiast-friendly Miata has many restrictions how you can configure one, which can make choosing one a bit tricky. You can't have the cheapest one or the leather-clad one with a limited slip differential, for example. And adding aftermarket parts on your own runs the risk of voiding your warranty. Long Road Racing, however, has a possible solution for creating the ideal, warranty-covered Miata. You may not be familiar with Long Road Racing, but you probably heard about one of its most-publicized products, the MX-5 Cup car. The car was developed by Mazda with the intention of creating a global spec series, and Mazda reports that about 140 of the cars have been sold so far. Every single one of those cars went to Long Road Racing to be specced out for racing before reaching their customers. So the company is familiar with the car, and has applied its expertise to its "Ultimate MX-5" program. The way the program works is, once you've purchased a 2016 or 2017 Miata, you can send it to the company to have it customized to your needs. The company has an extensive list of parts to choose from, all of which have been selected by the company to work well together. But if you need something outside of its offerings, or just need help choosing from the list, you can get in touch with the company to discuss how best to achieve your goals. Long Road Racing will also customize any trim level of Miata, and can even create a Miata Mazda didn't offer. For instance, you could have a Grand Touring with the leather interior, but also with the limited-slip differential and Brembo brakes from the Club model. All of these parts are fully warrantied by Long Road Racing for the length of the OEM warranty, and they don't void the factory warranty. We had the opportunity to try out a car customized by Long Road Racing at the M1 Concourse track in Pontiac, Mich. The car was there to sample alongside some of the MX-5 Cup cars as well as several of Mazda's stock road cars to drive on course. The road-going Long car started as a Grand Touring model, and it retains its heated leather seats and automatic climate control.

Mazda patent shows rotary placement in complex AWD hybrid layout

If we were playing alt-powertrain Bingo, a recent Mazda patent application filed in Japan would be one or two letters from victory. What's exciting about the patent, discovered by Japanese outlet T's Media via Motor Trend, is that while it makes a case for an internal combustion engine of any configuration, one of the drawings showing a rotary engine. The wild bit is that the whole powertrain comprises the ICE, a transaxle, two tiny in-wheel electric motors turning the front wheels, a third electric motor in the driveline, a capacitor, a lithium-ion battery, and three inverters. Motor Trend parsed the mechanics, and the way it reads, Doc Brown couldn't have done a better job. The rotary engine at the front turns the rear wheels, but not directly. Instead of a flywheel on back of the engine, the drawing shows a 25-kW electric motor and an inverter, then a driveshaft running to the transaxle. Along the axis of the transmission tunnel in a normal car, between the inverter and the transaxle, lies a 3.5-kWh battery running at 48 volts. MT writes that the electric motor can add its output to the ICE output to drive the rear wheels, or the e-motor can turn the rear axle on its own. Up front, two inverters and a double-layer capacitor join the ICE in the engine bay. The capacitor and tiny hub motors in the front wheels run at 120 volts, a higher voltage than the rest of the electrical system, so that the small in-wheel motors can generate the same torque as a larger motor running at a lower voltage. The AWD system acts on-demand. Given the signal, the capacitors discharge their energy to the wheel motors, and recover energy from braking. When the capacitors are at full charge, they send excess regen energy to the lithium-ion battery; conversely, the battery can recharge the capacitors when they're low and the front hub motors need power. The patent explains that the ICE works with the rear e-motor to drive the rear wheels at low speeds, the front motors called on to "generate an output only when a large output is required in the high vehicle speed range." The rather complicated system is focused on providing the benefits of a hybrid system and all-wheel drive, but at lower weight than one would expect. A rotary serves due to its compactness, but one of the drawings shows an engine with a V layout. Hub motors get dinged for adding unsprung weight, hence the small motors here.

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.
