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.

Watch this 1,500-hp Mazda MX-5 smoke a race track

In December 2014 we watched New Zealand drifter "Mad Mike" Whiddett assemble his RADBUL, an NC-series Mazda MX-5 Miata with a four-rotor engine aided by twin Garrett turbochargers. The Dr. Frankensteins at engine builders Pulse Performance expected their creation to be good for 1,500 horsepower. This year we get to watch Whiddett run the monster around Highlands Motorsports Park in New Zealand, brewing up enough tire smoke to set of fire alarms in the International Space Station. When the car was finished in February Pulse Performance put it on the dyno, toning down the boost because "the tires easily smoked the rollers." The result on the day was 1,032 horsepower from the 2.6-liter engine. When Whiddett campaigned it at the Forth Worth, TX round of this year's Formula Drift Pro Championship, he said tiny adjustments have a huge effect on the way the car behaves so they were still trying to find the right balance a few months into the season because of the testing limit outside of competition. Unsurprisingly, he also said the car "is so damn fast that I'm actually having trouble slowing down." RADBUL is the third in Whiddett's line of Mazda drift specials, after the RX-8 BADBUL and the RX-7 MADBUL.

2016 Mazda CX-3 scores 29/35 mpg EPA ratings

Looking for a subcompact crossover that won't cost you too much at the pumps? Your best bet is now the new Mazda CX-3, according to fuel economy figures released by the EPA. Mazda's new baby crossover has been rated by the US government agency at 29 miles per gallon in the city, 35 on the highway, and 31 on the combined cycle. That's in front-drive spec, giving the CX-3 better fuel economy than anything else in its class (at least, that is, with an automatic transmission.) Option it with all-wheel drive and you'll take a slight penalty at 27 mpg in the city, 32 on the highway, and 29 combined. According to Mazda that still "makes it among the most fuel-efficient all-wheel-drive vehicles available in the US." Whichever drivetrain option you go for, the CX-3 packs a 2.0-liter inline-four with direct injection (Skyactiv-G in Mazda-speak) good for 146 horsepower and just as much torque, mated to a six-speed automatic transmission. The first examples will begin reaching American showrooms later this summer.

As Mazda's first foray into the quickly burgeoning subcompact crossover class of vehicles, CX-3 provides those seeking a purposeful, stylish and sporty vehicle option that bucks convention. CX-3 offers standard keyless ignition and backup camera, and is available with features that are unrivalled in its class like Mazda Radar Cruise Control, adaptive LED headlights and Mazda's signature driving experience. Front-wheel-drive models have EPA-estimated fuel economy of 29 mpg city/35 mpg highway/31 mpg combined, while models equipped with Mazda's predictive i-ACTIV AWD have EPA-estimated fuel economy of 27 mpg city/32 mpg highway/29 mpg combined. That makes it among the most-efficient all-wheel-drive vehicles available in the U.S. "SKYACTIV Technology means we don't have to compromise when it comes to performance, efficiency and fun-to-drive dynamics," said Jim O'Sullivan, president and CEO, Mazda North American Operations.
