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.

Autoblog editors choose their favorite racecars of all time

If you like cars, there is a good chance that you like racecars. There's something about the science and the art of going faster, of competition, of achievement, that accelerates the hearts of enthusiasts. It doesn't matter the series, the team or the manufacturer – there's something about racing that stirs emotions and lifts spirits. It's that way with many of you, and it's that way with our editors. With that in mind, we offer a list of our favorite racecars of all time. Of course, we'd like to hear some of yours in the comment section below. 1970 Porsche 917 Compared to some of the obscure choices by my colleagues, I feel like the Porsche 917 is almost so obvious a pick as to not be worth mentioning. Still, when coming up with my answer, my mind invariably went back to this classic racer – specifically in its blue-and-orange Gulf livery – while watching Le Mans on DVD and later Blu Ray with my dad. Long, low and curvaceous, few vehicles have ever looked sexier lapping a track than the 917. More than just a pretty face, this beauty had speed, too, thanks to several tunes of flat-12 engines over the course of its racing life. In the early '70s, Porsche was a dominant force throughout sports-car competition, and the 917 (shown above at the 1970 24 Hours of Daytona) was the tip of that spear, including back-to-back victories in the 24 Hours of Le Mans. Largely without dialogue or really much of a traditional plot, Le Mans is like a tone poem of racing goodness. While the 917's importance to motorsports history is undoubtedly fascinating, it's still this cinematic depiction of the Porsche racer that draws me in most, especially with the volume cranked. – Chris Bruce Associate Editor 1964 Mini Cooper S How could everyone not be selecting the 1964 Mini Cooper S piloted by Paddy Hopkirk and Henry Liddon? That car, 33 EJB, took the first of British Motor Corporation's four Monte Carlo Rally wins (it should have been five, but French judges got the British Minis [and Fords] disqualified on a technicality regarding headlights... which its own car, the winning DS, was also in violation of). The tiny red car and its white roof beat out Ford Falcons, Mercedes-Benz 300SEs and scores of Volvos, Volkswagens and Saabs. This, along with the several years of dominance that followed, cemented the idea that not only could the tiny, two-tone Mini be a real performance vehicle, but that family-friendly city cars in general could be fun.

2016 Mazda MX-5 Miata won't get power folding hardtop

Following the reveal of the 2016 Mazda MX-5 Miata, more and more details (and rumors - oh, the rumors) are coming out regarding exactly what's in store when the car finally goes on sale. Our own Chris Paukert had plenty to say about the exterior and interior, and we've now seen the first photo of the engine. But a new report from Automobile sheds even more light on the 2016 Miata - specifically, that the power folding hardtop model won't be available, at least initially.
Automobile reports that the 2016 MX-5 will only be offered with a cloth top, and an insider confirmed that the mechanism is light and accessible enough that it can be raised and lowered with one hand from inside the car. Mazda officials would not comment on the availability of a hardtop in the coming years.
That said, a hardtop Miata isn't out of the question. There will likely be some sort of fixed roof available - even as a one-piece, lift-off accessory - if only for club racing. Also, remember that the current NC Miata's hardtop is the only one on the market that doesn't take up any additional trunk space, so it's an attractive proposition for buyers. Currently, the power hardtop is only offered on the Club and Grand Touring MX-5 Miata trims.
