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.

2002 Mazda MX-5 Miata powered by a Jaguar-sourced V6 for sale

Cars & Bids, a relatively new site that specializes in auctioning modern enthusiast cars, is selling a 2002 Mazda MX-5 Miata. While that's hardly unusual, this example lost its four-cylinder engine and gained a Jaguar-sourced V6. Pulling a 3.0-liter six out of a 2000 S-Type and dropping it into an unsuspecting Miata is apparently easier than it sounds. England-based Rocketeer offers a kit that makes the swap reasonably straightforward, though the listing notes the factory air conditioning system is not compatible with the new engine. Cold air aside, the installation is done so neatly that it looks like Mazda envisioned the Miata with a bigger engine. Jag's V6 inevitably adds weight to a roadster praised globally for its nimble handling, but it also brings a whole lot of horsepower to the table. Left stock, a 2002 Miata is powered by a 1.8-liter four-cylinder that makes 142 horsepower and 125 pound-feet of torque. The example listed on Cars & Bids puts 220 horsepower and 221 pound-feet of torque under the driver's right foot, figures that easily offset the weight gain. And, somewhat surprisingly, the six spins the rear wheels through a stock five-speed manual transmission. Flyin' Miata sway bars and Koni shocks improve handling. Close the hood, and this Jagazda looks like a run-of-the-mill 18-year-old Miata. The seller made no modifications to the body, it's still painted in its original shade of silver, and he kept the stock 15-inch wheels. The dual exhaust tips hint at the V6, but they're subtle enough to surprise more than a few racers at the next autocross event. The auction is live now, and bidding stands at $4,250 as of writing with about three days left before the hammer drops. If you miss your chance to bag it, several shops sell kits that let skilled shade-tree mechanics shoehorn Mazda's K-Series V6 (which powered the MX-6 and the Ford Probe, among other cars) into an older Miata.

Bighearted enthusiast rescues stranger's Mazda RX-7 from floods

With Tropical Storm Cristobal charting a path for the Gulf Coast, a Biloxi, Mississippi, local named Khuong Nguyen wanted to get his FD-series Mazda RX-7 out of the storm — the coupe had some bad seals that would let in rain. He parked the orange and black coupe in the bottom story of a parking garage at the city's Golden Nugget Casino, which kept the rain from getting in. But Cristobal came on stronger than expected, creating a new threat of water from below when the parking garage began to flood. Austin Owens, a Gulfport resident about 10 miles from Biloxi, saw photos of the RX-7 with water up to its rockers on a local Cars and Coffee page. As he would later tell Jalopnik, the RX-7 being one of Owens' dream cars, he decided he needed to rescue it. Just to make sure we're all on the same page, a young man braved a tropical storm in his own vehicle to save a stranger's RX-7 in another city. Owens dragooned a friend and hopped in a Ford Bronco, dodging closed roads and fording three or four feet of water on open roads. They drove to Home Depot to pick up cinder blocks, then headed to the Golden Nugget parking garage. As Owens and his friend arrived, they met Nguyen and a couple of his friends pulling Nguyen's second car, a Ferrari 360, out of the garage on a trailer. The RX-7 had already been set on wood blocks, thin bricks, and some orange wheel chocks, but the stilt job wasn't high enough in front; the water in parts of the garage was knee deep. Owens jacked up the RX-7 to get the cinder blocks under the front wheels; the rear end was fine, due to the slope of the garage floor. Success. As one of Nguyen's friends told Jalopnik, Owens' actions "did give us adequate time to combat the rising water." The success came at a cost, though, Owens reporting, "We actually killed the [BroncoÂ’s] transmission on the way out. We actually had to drive in second gear all the way home" due to floodwater seeping into the transmission. He has no regrets, explaining his derring-do with, “ItÂ’s a rare car ... I would hope somebody would do the same for me if I was in the situation with a car of that stature. I didnÂ’t have it in my heart to leave it there." With the story blowing up on Facebook, he told the legion of enthusiasts sending their respects, "Appreciate the love, but IÂ’d expect the same for one of my cars," followed by, "Alright, whoÂ’s down for some Forza?" Save for the original seal issue, the RX-7 came out of the storm with no issues.
