Mazda development chief discusses future rotary platform

The switch can again be flicked from "The Rotary Engine is Doomed" to "The Rotary Engine Lives!" Mazda is re-tooling the once nearly forgotten rotary to work as a range extender for hybrid vehicles, with a chance for it to do even more than that. The latest information sounds rather promising for those still holding out a candle for the rotary. Mazda's powertrain development chief, Ichiro Hirose discussed future rotary plans with the Australian Drive at the CX-30 crossover's launch. Hirose told Australia's Drive that Mazda is currently working with a very flexible and efficient rotary hybrid platform that doesn't necessarily come with the heavy emissions and fuel consumption baggage the rotary engine has earlier been saddled with. Hirose calls the rotary-based solution "XEV," referring to its adaptability. "It has the generator function and also it can be used to provide the drive force to give you traction. [...] Because the rotary engine is compact in terms of its packaging size [and] if we should choose to do so we can have the generator, rotary engine and electric motor all in one [driveline] because of the small packaging." The result is an electrified platform that could be made to work as a mild hybrid, series hybrid or a battery electric vehicle with a rotary range extender (if given a plug), depending of the required implementation. It's as if Mazda had a slider to adjust the balance of using a rotary engine and using electric power, to make the platform more of a jack-of-all-trades. Hirose explained: "If you reduce the other way around it could be a pure battery-electric, using really the rotary engine as a range extender and, according to the balance, you can even provide something akin to the series hybrid that is providing the drive force. [...] So, we are looking at a wider coverage and scope. Based on this architecture it allows us to do that, to explore the huge range of applications we can have with the rotary." The platform would also be flexible when it comes to meeting various stringent emissions standards. To be able to sell XEV-based vehicles globally would mean introducing a certain setup for one region and one for another, keeping in mind when the rotary power would kick in and how. While Hirose keeps the question open whether these vehicles would make it for sale in the United States, he says Mazda would be able to make them pass U.S regulations. "I'm just saying that — theoretically — if we were to introduce it in the U.S.

More head-up displays are coming to a dashboard near you

With the exception of Apple products — $1,000 for a freakin' smartphone? — one great thing about tech is you typically get more for your money with each passing year. This is particularly true with automotive tech: Features like driver assists and surround-view cameras that were once exclusively available in luxury vehicles now come standard even on some economy cars. The same thing is slowly happening with head-up displays (HUD). For example, the 10-inch HUD in the 2018 Toyota Camry is one of the largest and best HUDs I've seen in any car. And a big improvement on the much smaller HUD in the latest Toyota Prius. Mazda is another mainstream brand that offers HUDs in several of its vehicles. But instead of embedding expensive components in the dash and using a special windshield, the HUDs in the Mazda3 and Mazda6 use a thin plastic lens that folds down when not in use. MINI has a similar solution, but this low-cost approach has limits in terms of size and position of the images compared to traditional HUDs that use the windshield as a screen. We're also starting to see similar lens-based aftermarket options that can be added to any car. Last year I tested a portable HUD called Navdy that taps into a car's OBD-II port to provide info on speed and RPM and uses built-in GPS and Google Maps to show the surrounding area, display speed limits and route you to your destination. Navdy also connects to an Android or iOS smartphone via Bluetooth to display data from phone calls, texts and music playing on a connected device, and it's simple to use and easily visible in almost any lighting condition. While Navdy is still available online, late last year the company ran into financial difficulties, and product support has been halted. I recently tested a new portable HUD called Hudly that's not quite fully baked and falls short of Navdy because it doesn't tap into an OBD-II port. Since a companion smartphone app for Hudly isn't scheduled to launch until next month, for now it only mirrors what's on a smartphone. So it can be used for nav and other apps, and its features are very limited. Between automakers adding HUDs in more reasonably priced cars and the aftermarket filling in the gaps for existing vehicle owners with add-ons, the technology is becoming more prevalent and affordable. And it's also getting better.

Premium design and diesels: Mazda may be the next VW

At the Chicago Auto Show, we had a chance to sit down with Jacob Brown, a Mazda PR representative, and Jacques Flynn, a lead exterior designer at the company, to talk about design and where the company is going. One of the themes of our discussion was the company's desire to move its lineup toward a more premium, upscale feel and image – both in terms of vehicle design and powertrains. We realized the company may be looking to take a page from Volkswagen's American playbook, positioning itself as a prime purveyor of affordable, upscale – and most importantly, fun to drive – automobiles. In the case of design, Flynn talked about how Mazda's KODO design language is going to evolve; that the goal is to simplify and refine the look. We discussed the CX-5 as an example of this evolution. Flynn pointed out that the goal was to add more refinement and simplicity, and showed how Mazda achieved this on the CX-5 by straightening the curves from the previous model to give it more visual length and a more taut shape. The grille also was given more depth and detailing, which isn't simplified per se, but does provide a more premium look. View 9 Photos Mazda's upcoming diesel engines are another piece to Mazda's premium puzzle. The company will finally offer a diesel on the CX-5. While Mazda planned not to use urea-injection, it finally resorted to the system so the engine could both meet performance benchmarks and emissions standards. In addition to the efficiency of the engine, Brown said that diesel engines have a premium nature for buyers. This is due in part to the luxury automakers that mainly offer them in the US, such as BMW and Mercedes-Benz, and to the fact that the technology will add some cost to the product. If all of this sounds familiar, it's because you know these characteristics used to describe Volkswagen: a company known for upscale, affordable cars, providing great driving dynamics – and formerly, for efficient and fun-to-drive TDI diesel engines. While we didn't touch on the driving experience of modern Mazdas in our interview, you can simply look at any of our reviews to see that we generally like what the company builds. The only downside is that we may have to wait a while for some models, and others may never show up here. Brown and Flynn both said that the Mazda2 is unlikely to be offered in the US as anything other than the Toyota Yaris iA, since it's hard to convince people that a subcompact is premium. No surprise there.
