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.

Mazda heads to Daytona with fierce-looking Mazda3 TCR race car

Hatchback lovers rejoice, Mazda has turned its stunning five-door into a race car. The Mazda3 TCR will participate in the 2020 IMSA Michelin PilotChallenge and will first debut in January 2020 during the Rolex 24 weekend in Daytona, Florida. Mazda is set to return to touring-car racing (TCR) with an adaptation of its popular compact car. The Mazda3 TCR has a lot of exterior changes that make it visually different from its road car brethren, and a whole lot more performance alterations we can’t see. A massive wing stands tall at the rear, and itÂ’s matched with a bulbous widebody kit with cooling vents behind the front and rear wheels. The new dress also has a front splitter, side skirts, and rear bumper aero. Further enhancements include a new hood, a single centered exhaust pipe, and new wheels and tires. Under the hood, the Mazda3 TCR has a turbocharged four-cylinder engine that makes 350 horsepower. It pairs with a six-speed transmission with paddle shifters. Mazda collaborated with the same company that manufacturers the Global Mazda MX-5 Cup Car, Long Road Racing, to develop the TCR. It is homologated for global racing in 36 TCR championships, and it will make its debut at the four-hour Endurance Challenge at the Daytona Rolex 24.  

Driving a $500 junker in a 500-mile off-road rally race | 'The List' #0500

Jessi and Patrick have done some insane rally races on "The List," but in an effort to continually out-do themselves, this might be the craziest yet. It's called the Gambler 500, and the idea is that 2,000-plus participants take $500 cars and drive them 500 miles across Oregon, mostly off-road. It's a maniacal mishmash of cars with not enough doors, too many doors, airplane wings strapped to the tops, graffiti'd cartoons on the hoods, stuffed animals hanging out the windows — you get the idea. Our hosts start the race with an absolutely epic Mazda Miata sitting atop super swampers. It didn't have a top, but have no fear because it had a roll cage, so ... that's better? Unfortunately though, they didn't have time to customize the car fully to their liking before the race, so the first stop after the starting gun was naturally a garage sale for some knickknacks to give the car a little more flair. One of the defining aspects of the Gambler 500 is having the most obnoxious, bonkers car possible, and the old Miata needed a bit of a kick in the ass. Thankfully, the crew found the largest teddy bear in existence, strapped that bad boy to the roll cage, and they were on their way. There are a few routes you can choose to take in the Gambler 500, and our crew chose the most challenging, called "The Devil's Butthole." A hilarious name for an outrageously fun route, it's definitely not one that many Miatas have likely tackled. And therein lies the gamble: Will they make it to the end? As always, you'll have to watch the episode above to find out.
