Bauer Catfish is a Miata-based trackstar in the making [w/videos]

We're not trying to make a joke here. The creation you see above really is called the Bauer Catfish, and while the name is about as attractive as your average bottom feeder, the car itself is built on a sexy notion. Take the mechanical bits of one 1990-2005 Mazda MX-5 Miata, add in a tube chassis for as little weight as possible, complete with some custom body work and go forth. Bauer says the finished product weighs in at just 1,550 pounds, and the company will be happy to pull the stock four-cylinder to drop in a healthy General Motors LS V8.
The pre-production prototype shown above competed in last year's 25 Hours of Thunderhill, finished the race and earned a spot on the podium in the "anything goes for sports racers" ESR class. Very cool.
If you're looking for a dedicated track car, it may not get any better than this for the money. Expect to pay around $13,900 depending on options, plus the cost of your donor Miata. That's a good sight cheaper than a used Chevy Corvette Z06 and likely to be quite a bit more fun. After you're done watching it in action in the brief videos below, check it out over at Bauer Ltd.

Mazda rumored to bring rotary-powered RX-9 concept to Tokyo

Stop us if you've heard this one before: Mazda will bring a rotary-powered sports car to the next big auto show. Okay, so we stopped for a second, but the show must go on. Following an official teaser image (shown above) late last month, Motoring.com.au has what it claims are renderings of the curvy, two-door coupe – called the RX-9 – that Mazda will bring to the Tokyo Motor Show later this month. The images show a far softer styling than Mazda's current crop of Kodo-inspired vehicles, while the overall look screams of a modern-day Cosmo Sport, the Japanese brand's first rotary-powered vehicle. And though that connection alone might be enough to justify whisperings of a successor to the RX-7 and RX-8, Motoring claims there will be an even more overt sign of this concept's power source. "Look to the Cosmo Sport," an inside source told the Aussie website, signaling that the Mazda stand would feature the vintage two-door. "The Cosmo has no earthly reason for being there unless..." The rotary rumor, if it comes true, won't exactly be what we're use to. While Motoring brings up the previously reported 16X – a 1.6-liter two-rotor – it builds on our 2013 report. According to the Aussies, the new engine could feature a two-stage electric turbocharger, be paired with a hybrid powertrain, offer up to 450 horsepower, and we're guessing, be hilariously complicated. Joking aside, it sounds like Mazda's goals here are admirable. A rotary-equipped sports car that could counter the 1.3-liter RX-8 engine's appetite for fuel and improve on its mediocre low and mid-range torque would be interesting indeed. As for those renderings, Motoring has front and rear three-quarter images. Comparing the rear with our original teaser leaves the look open to interpretation, but after seriously upping the exposure on the teaser (thanks Photoshop), the taillights and overall profile shape look to be a spot-on match. In front, the long hood shares some Kodo elements, like the headlights and grille, but its undeniable coupe shape – a long hood and very short deck – are far more organic and, dare we say, calm, than Mazda's other vehicles. You can take a closer look at the renderings over at Motoring's website. Do that, and then head back and let us know what you think of these RX-9 rumors. Is Mazda finally going to be bringing a rotary back to market?

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.
