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.

Cars we're thankful we drove in 2019

We drove a lot of cars in 2019, and there's still a month to go. We drove them in our home office in Michigan, at our remote offices in Seattle, Portland, Ore., and Columbus, Ohio, and throughout the globe on myriad press launches. We could count them, but hey, that seems boastful.  Instead, we want to be thankful. Not only for the opportunity to do this wonderful task some might describe as a "job," but for the new, shiny cars that brighten our days (and most hopefully yours). We asked our fellow editors which car they were most thankful to drive in 2019 ... here are our answers. 2019 Hyundai Veloster N Performance Senior Editor Alex Kierstein Every once in a while a car comes along that changes the narrative on a company or its segment, and everyone scrambles to experience it for themselves. This year, for me, that car’s the Veloster N Performance, perhaps the most transformative car the companyÂ’s ever built. Everyone whoÂ’s driven it, here and elsewhere, says it captures all those intangibles that make great driving hatchbacks great. And IÂ’m thankful that I got a go in it before all of them left the fleet, because it does. It upends the segment long dominated by the GTI, a car that nails its brief. The N is rowdy and loud, sure, but it also has some of the most deftly tuned suspension IÂ’ve come across in a front driver. My advice: if youÂ’re in the market for something fun and unique, go test drive a Veloster N. I think youÂ’ll be thankful you did. 2019 Hyundai Veloster N View 47 Photos 2019 Audi E-Tron Senior Editor, Green, John Beltz Snyder IÂ’m pleased that I got to drive the Audi E-Tron. ThatÂ’s high praise for a year in which I also drove the stellar Jaguar I-Pace. The E-Tron, while not as sporty as the Jaguar, is excellently executed, and feels like a more refined, polished offering. ItÂ’s quick, whisper-quiet, comfortable, stylish inside and out, and incredibly sturdy. Some may lament that it doesnÂ’t do much to stand out from ICE vehicles, but I donÂ’t think it needs to. What it does need to do is win over the electro-skeptical, and I think Audi put its best foot forward with a crossover that can do just that, and more. So, yeah, not only am I thankful that I got to drive it, IÂ’m glad that itÂ’s compelling enough that itÂ’ll hopefully make potential customers feel the same. 2020 Audi E-Tron View 13 Photos 2013 Peugeot 508 West Coast Editor James Riswick My choice totally sucks.

This is what a 1,200-hp twin-turbo 4-rotor looks like in a Miata

We've seen the diminutive Mazda MX-5 Miata swallow plenty of big engines, but New Zealand drifting ace "Mad Mike" Whiddett is roaring into where-no-man-has-gone-before territory. Wanting to replace his 515-horsepower "MADBUL" RX-7 and its twin-turbocharged, three-rotor 20B engine, his new ride is an NC-series Miata with four rotors and twin Garrett turbochargers courtesy of Pulse Performance Race Engineering. It is called "RADBUL," and expected power at standard boost is 1,200 hp, but the builders at Pulse Performance think it will get up to 1,500 hp at full boost. And yes, that exhaust exits through the hood. Four-rotor engines are actually popular - builds are detailed on forums like this one from 2007 and this one from 2008, this UK company or this Canadian company will sell you one complete - but they're usually being prepped for an RX-7. Mad Mike's choice of a Miata for this enterprise makes this about as extreme as you can get, short of throwing it into a Mazda R360. You can watch Mad Mike tell the story of the build in the video, and check out the first and second installments about the build on the Red Bull site.
