Junkyard Gem: 1990 Mazda 929 S

In the late 1980s, Toyota, Nissan, and Honda were cleaning up in the American market with the Cressida, Maxima, and Legend, respectively. Mazda wanted some of those dollars, so the HC-series Mazda Luce was modified for the US market and sold here as the 929. It had rear-wheel drive, a powerful V6 engine, and lots of luxury features, but not many were sold. Here's a rare '90 that I spotted in a San Francisco Bay Area self-service yard. In 1990, the sporty 929S version got 190 horsepower from its DOHC 3.0-liter V6. Unfortunately for Mazda, American buyers associated the marque with sensible econoboxes and screaming rotary engines, not luxury machinery, at the time. For the 1990 model year, American-market cars were required to have either a driver's-side airbag or automatic seat belts. The 929 had the automatic belts, the less said about the better. The Luce-based 929 became the Sentia-based 929 for the 1992 model year. Meanwhile, the new luxury brands from Honda, Nissan, and Toyota were kicking the crap out of 929 sales; Mazda had planned to launch the Amati brand in the United States, but didn't have the resources to follow through. The last 929s were sold in the United States for the 1995 model year. Related Video: Featured Gallery Junked 1990 Mazda 929 S View 16 Photos Auto News Mazda

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 patents show rotary engine for range-extended EV

Two years ago, Mazda introduced a fascinating range-extended electric car called the Mazda2 RE Range-Extender. It took an electric Mazda2, and dropped in an itty-bitty 330cc rotary engine. It wasn't the rotary-powered sports car we had hoped for, but it seemed like a unique way to keep the quirky engine alive and kicking. But not long after the car's reveal, it seemed to disappear. Now the basic idea has resurfaced with a few modern updates in a couple of US patents. The first patent is pretty straightforward and describes a range-extended EV similar to the BMW i3. At the front is an electric motor driving the front wheels. At the back is an internal combustion engine that powers an electric generator. In the middle is a lithium-ion battery for storing and delivering electricity. It's the same set-up as that Mazda2. The second patent is for an engine start-and-stop system, but specifically for rotary engines. The system is designed to shut off a rotary engine when not needed, much as modern piston engines do. It also stops the rotor in a position that closes the intake port to ensure no fuel or exhaust emissions slip out through the intake tract. This is necessary since there are no valves in a rotary, and air and exhaust come through ports that are "opened" and "closed" by the rotor itself. The patent also describes the possibility of firing a spark plug after the fuel has been cut to eliminate any leftover fuel emissions. This system would theoretically improve a rotary engine's fuel economy and emissions significantly, which would be a boon as those are two of the rotary's major weaknesses. The rotary-engine patent also includes the same range-extended powertrain drawing as the first patent. It's there as a description of a possible application. And in such an application, where the rotary wouldn't have to run all the time, the system could take advantage of the rotary's inherent strengths. Weight can be kept low thanks to the engine's small dimensions, which should help in keeping the car sprightly and efficient. Rotaries are renowned for smoothness, too, so it shouldn't need too much refining and sound deadening, the latter of which adds more weight. The small size would also help with packaging, leaving more space for people, cargo, or possibly batteries. And since it has been patented, the company may be looking to bring the system to market.
