Mazda rotary engine returning, in an autonomous Toyota delivery vehicle

With the return of the Toyota Supra, the Lotus Esprit and Mazda RX-7 probably share the trophy for hardcore sports cars we'd most like sequels for. The Esprit's too hopeless to consider. Mazda continues to speak in riddles about a new RX-7, but the company has confirmed that the RX-7's heart will return: The company's building a rotary-engined range-extender engine for an autonomous Toyota. At this year's Consumer Electronics Show, Toyota announced its e-Palette autonomous electric delivery vehicle. The e-Palette will come in bus, shuttle, and car versions to service the delivery needs of companies like Amazon, Pizza Hut, and Uber. They'll also be built in custom configurations such as mobile hotel rooms and emergency command centers. Toyota owns 5.25 percent of Mazda, the two automakers recently signed a deal to open a factory in Alabama, and Mazda's known for ace work with small engines. It's not surprising that Toyota chose Mazda for help with the e-Palette, but the rotary aspect is novel. Mazda U.S. president Masahiro Moro said, "This is a very suitable engine to run a generator because it's compact and lightweight, with no noise or vibration, and it has very good fuel economy." There have been rumors of this development previously, as far back as 2016, then again last October in reference to an electric architecture Mazda intended for release in 2019, but Toyota was never mentioned. As to pining for that RX-7 redux, Mazda's head of powertrain said the company's overcome the technical issues of a sports-car-sized rotary engine — the challenge is making a business case for such a sports car. We think the RX-VISION made the case three years ago, and it's already fitted with the Skyactiv-R rotary. Separately, a Toyota spokesman added that the two companies are looking into whether the rotary can be useful beyond the electric car. That's not much to go on when it comes to pining for another RX-7, but hope lives on a scanty diet. Related Video:

Mazda to use rotary engine as a range-extender with its first electric vehicle

There's more news from Mazda at the Tokyo Motor Show, where the brand made a big splash, including new developments in its never-ending rotary engine saga. First, Mazda execs confirmed that the Japanese automaker will bring back the rotary engine as a range-extender and battery juicer for its first electric vehicle in 2019. But secondly, the company won't have a rotary-powered successor to its RX-7 and RX-8 sportscars in time for the company's centennial anniversary in 2020. Autoblog previously confirmed that Mazda is planning to have an EV in 2019 that will be available in both pure electric and range-extending versions. Now, the Australian website Motoring reports that the global EV will feature a powertrain similar to the experimental Japan-only Mazda2 (Demio) EV, which used a single-rotor engine as a generator to power the battery pack and increase its driving range. The publication says Mazda plans to release a series of plug-in hybrids based on existing models around 2020, then a pure electric car co-developed with Toyota and Denso in 2021 as part of the EV Common Architecture Spirit Company joint venture. A Mazda spokesman tells Autoblog the company couldn't confirm any details about future products. Meanwhile, enthusiasts shouldn't wait for a rotary-based production version of Mazda's RX-Vision concept from 2015. Motoring cites two executives who explain that the company simply lacks the capital necessary to invest in developing the new model in time for its 2020 centennial. Mazda debuted its rotary engine 50 years ago in the Cosmo Sport in part as a way to stand out from its larger Japanese competitors. The engine, which uses a spinning three-tipped rotor in place of pistons, is smaller and lighter than conventional piston engines, with a greater power-to-weight ratio and quieter, smoother operation. But it delivers less fuel economy and higher emissions — two weaknesses that could be improved via a stop-start system Mazda has developed, based on a pair of U.S. patents. The company has also been hard at work developing its next-generation Skyactiv-X engine, which uses highly precise combustion ignition technology to deliver significant gains in fuel economy and power.Related Video:

Mazda CX-30 'just right' crossover will head from Geneva into production

As more and more customers move into the crossover segment, the less the segment is one-size-fits-all, or even three-sizes-fit-all. As such, Mazda has taken the opportunity at the Geneva Motor Show to offer a new, "just right" crossover to its lineup. The 2019 Mazda CX-30, as it's called, slots between the diminutive CX-3 and the compact CX-5 crossovers. The CX-30 shares the "Kodo" (meaning "soul of motion") design language Mazda does so well, and the execution here is excellent, too. We love the long hood and simple but elegant curves, the way the light reflects off the sides in dramatic waves. Its no surprise that Mazda chose its Soul Red Crystal to show off the new model. Mazda says it had four goals for the CX-30, two of which had to do with the size of the vehicle. It needed to be small enough to be highly maneuverable, so that drivers wouldn't hesitate to take it anywhere they need to go, but it also had to be roomy enough to provide a comfortable space for multiple passengers to easily enjoy one another's company. Mazda wanted the design to "embody the joy of owning something that matches your sensibilities." Finally, it had to perform in a way to provide peace of mind and a relaxing driving experience. Mazda will offer the CX-30 with its Skyactiv-G 2.0 gasoline engine with cylinder deactivation, Skyactiv-D 1.8 diesel engine and its new Skyactiv-X engine with gasoline compression ignition. Both gasoline engines will use Mazda's mild hybrid technology to help improve fuel economy without sacrificing performance. The CX-30 will also be offered with Mazda's I-Activ all-wheel drive and G-Vectoring Control Plus for maximum grip and stability. It will be available with either a six-speed manual or six-speed automatic transmission. The CX-30 is equipped with a driver monitoring system to improve safety using an infrared LED and camera to watch the driver's face for signs of drowsiness or inattentiveness. It'll alert the driver to pay attention, and will sound the braking alert earlier. Other active safety systems include available Front Cross Traffic Alert and Cruising & Traffic Support, the latter of which will employ accelerator, brake pedal and steering operations in traffic jams to help avert driver fatigue. Mazda hasn't said whether it will offer the CX-30 outside of the European market. Related Video:
