Patent application suggests Mazda rotary return

A recent patent application by Mazda reveals that the Japanese automaker is still working on the rotary engine. This could in fact be the Skyactiv-R engine found in the RX-Vision concept from the 2015 Tokyo Motor Show. As with anything Wankel-related, nothing is certain until Mazda makes a production commitment. But this filing suggests that serious development is happening in Hiroshima. The 2011 Mazda RX-8 was the last rotary-powered car you could buy in America. Slow sales, poor fuel economy, and tighter emissions standards prevented Mazda from committing to a follow-up. But the fundamental principles of the rotary - compact size and light weight - perfectly fit Mazda's Skyactiv ethos. (For an explanation of how rotaries work, click here.) In this new engine the intake port sits at the bottom of the engine with the exhaust port on top instead of the other way around. That allows for lower mounting, which improves a car's center of gravity. This rotary is also turbocharged. Putting the turbo up high helps ensure it doesn't get in the way of any body or chassis crossmembers. The implication of those claims is that somebody is thinking about how to put this engine in a car. There are other benefits as well. The short path from the exhaust port to the turbo ensures minimal turbo lag. It also allows for a close-mounted catalyst on top of the enigne, which will help emissions. Another innovation in this new engine is a triangle-shaped rotor that covers part of the exhaust port. This allows for different exhaust flow characteristics. The filing claims that that two of the four orientations allow for less airflow resistance in the exhaust port. As in previous Mazda rotaries, there are two spark plugs to manage ignition timing and combustion. But unlike in the 16X concept, Mazda's last public display of such an engine, the new rotary uses port fuel injection. Keep in mind this is only a patent application. A Mazda spokesperson refused to comment on future product, but commented "As we stated at the Tokyo motor show, Mazda is doing all that it can to bring a rotary to the market." In the meantime, keep your RX-7 prayer candles lit and hope for the return of the rotary before the end of the decade. You can bide your time by reading the entire application here.

World Car Awards finalists snub American-branded vehicles — except for Bronco

The list of World Car Awards has been whittled down to 10 finalists, but only one American brand — Ford — appears among the remaining nine carmakers for this yearÂ’s top award. The Bronco is there, and it also is balloted as a finalist in the design category. The other categories are performance car, urban car, electric vehicle and luxury model. Each category has five finalists except World Car, which has 10. One brand conspicuous by its absence in any category: Tesla. The winner in each is scheduled to be crowned March 27 at the New York International Auto Show in Manhattan. This year marks the 20th year of the World Car Awards and the partnership with the New York show. The selection process involves 100-plus automotive journalists from 29 countries who vote, as they review and test-drive the eligible vehicles for the 2024 awards. Their journey is captured virtually on World Car TV. If youÂ’re counting, the brands that appear most on the six finals lists are Mercedes-Benz (four times), BMW (also four), Hyundai (three), and Volvo (three). HereÂ’s the full listing. A video clip showing all of them is here: World Car -BYD Seal / Atto 4 -Ford Bronco -Hyundai Kona / Kona Electric -Hyundai Santa Fe -Kia EV9 -Mazda CX-90 -Subaru Crosstrek -Toyota Prius -Volkswagen ID.7 -Volvo EX30 World Car Design of the Year Ford Bronco Ferrari Purosangue Toyota Prius Volvo EX30 Zeekr X 2024 World Electric Vehicle BMW i5 Kia EV9 Mercedes-Benz EQE SUV Volkswagen ID.7 Volvo EX30 2024 World Luxury Car - BMW 5 Series / i5 - Lexus LM - Mercedes-Benz CLE - Mercedes-Benz E-Class - Mercedes-Benz EQE SUV 2024 World Urban Car  - Abarth 500e - BYD Dolphin - Lexus LBX - Suzuki Fronx - Volvo EX30 2024 World Performance Car - BMW M2 - BMW XM - Ferrari Purosangue - Hyundai Ioniq 5 N - Porsche Cayenne Turbo E-Hybrid

Mazda teases electric car again with peek at interior

Mazda is again touting the new electric vehicle it plans to reveal at the Tokyo Motor Show, this time teasing it from the inside. A 15-second video homes in on features found on the center console, namely, the blocky shifter for the automatic transmission, a large, knurled rotary dial for infotainment control, and a smaller dial we'll assume is for volume control. As for what else we can make out, if we were to guess, we'd say the slick surface to the right of the shifter is a screen. It'll be interesting to see how Mazda designers filled the space between the seats, but we're surprised Mazda went with such a substantial shifter; this being an EV on a new, dedicated platform, designers could have minimized the focus on shifting and opened up a host of other uses.  A brief press release informs us that Mazda's worked to liberate the cabin from structural clutter, though. The brand says the interior is "designed to give occupants a feeling of being 'enveloped in openness,'" and that the "goal [is] to make spending time in the car a comforting experience that allows customers to be themselves." Empty spaces throughout the center console "create a connection between the driver and passenger seat areas," so perhaps what looks like a free-floating console demo section in the video is what the unit will look like in the car. Elsewhere, the EV will feature eco-friendly materials. The EV isn't expected to make it to America, its powertrain designed to satisfy residents of particularly dense urban environments. The running gear should stick close to the drivetrain developed for the e-TPV prototype, meaning a 35.5-kWh battery powering a single electric motor at the front axle producing 138 horsepower and 195 pound-feet of torque, and a single-speed transmission. Range is thought to be around 120 to 150 miles on a charge. The onboard charger can handle 6.6-kW home charging and 50-kW rapid charging. Eventually, a range-extender version with a rotary engine should join the lineup; Mazda said it chose a rotary because even though it's less efficient than competitors' ICE range extenders, it's so much quieter. The debut of what everyone expects to look like a crossover happens on Oct. 23.
