Mazda 16X rotary engine two years away, will arrive in all-new model

We last reported on Mazda's next-generation rotary engine project in June of 2012 when the automaker built its last Renesis-powered RX-8, but rumors of this new engine's development had been around way before that final car left the production line in Japan, last year.
We now have enthusiastic confirmation that this next-gen rotary engine is really and truly going forward. It is still referred to as 16X and has several priorities. First is to lower fuel consumption compared to the RX-8's engine, while still making gains in terms of performance. The second is to reduce the burning of oil that was happening at the highest revs. And the third and final priority, and perhaps most key for enthusiasts, is to give the powertrain a big torque upgrade.
What we were told by a Mazda USA insider (while we are all here together at the festivities in Monterey) is that the first application of the new 16X engine will be happening in two years' time in an as yet undisclosed new model. Oh, the mind races to our eternal Mazda wish list...

2020 Mazda CX-30 Review & Buying Guide | The new sporty

Is it a sporty crossover? Is it a tall hatchback? However you want to view it, the new 2020 Mazda CX-30 is a compelling new entry that delivers the sort of engaging driving experience and premium cabin environment you get in the company's 3 hatchback, but with the higher seating position of a crossover. Basically, if that Mazda3 had a child with the bigger CX-5, this is pretty much what you'd get, and we have to say it's a pretty good kid.   In terms of size, the CX-30 fits into a niche of in-betweener SUVs that slots between compact models like the CX-5 (plus the Honda CR-V, Toyota RAV4, etc.) and sub-compact ones like the Mazda CX-3 (plus the Honda HR-V, Hyundai Kona, etc.). If you don't have small children, and the car seats and strollers that come with them, it's a size that should make sense. The price is compelling too, especially when you consider the CX-30's high-end cabin and just how terrific it is to drive. With its tautly tuned chassis, communicative steering and sharp throttle response, the best words to describe it are "budget Porsche." Now, we should note that the Mazda3 is even better to drive and pretty much offers the same cabin space, design and quality. We also think it looks better. Nevertheless, people like sitting up high, and the CX-30 definitely satisfies that requirement. What's new for 2020? The Mazda CX-30 is an all-new model. What's the CX-30's interior and in-car technology like? Like the Mazda3 with which it shares so much, the CX-30's cabin makes you go "wow" considering its price and the vehicles with which it competes. Whatever trim level you're considering, the key to this wow factor is how Mazda's new dash design scheme removes visual clutter by reducing switchgear and effectively hiding air vents and door handles. It's then augmented by standard two- or three-tone color schemes – cars with cloth or leatherette vinyl upholstery are accented with black and blue dash/door trim, while those with leather get black and brown. For a car in the $20,000-$30,000 range, it looks and feels special. It's also of a high quality and quite functional. The steering wheel, which looks sensational, is an absolute treat to hold and has intelligently designed buttons/switches for the infotainment and cruise controls. There's considerable center console space, including a configurable under-armrest bin, and a decently sized forward bin for a smartphone.

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.
