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.

2016 Mazda MX-5 Miata a knight in white satin

We're not going to lie to you. The reason you're seeing the fourth-generation Mazda MX-5 Miata on these pages again is solely because this is the first time we're seeing the roadster displayed in a color other than the ruby shade it was first shown in. Okay, okay, so this is the first time the Miata is being displayed at a North American auto show other than SEMA, and we'd say that this is the first time Mazda is showing a US-spec model, but clearly this is a right-hand-drive car. Either way, there's still not much to it yet, especially since Mazda is still withholding power and performance figures.
As expected, the ND Miata, as it is already known among the cognoscenti, will receive a 2.0-liter Skyactiv four-cylinder and the buyer's choice of a six-speed manual or a six-speed automatic here in the US. The 1.5-liter model engine that had been linked to the car back in the rumormill stage will not make it to our showrooms.
Preliminary specifications still show the Miata measuring just 154.1 inches in length overall, with an increased track width to 68.1 inches and a low, low overall height of 49.0 inches. Despite the larger-displacement engine and its presumably heavier weight, Mazda is still claiming ideal 50:50 weight distribution and a weight loss of over 220 pounds versus today's NC generation. All of which sounds like the Miata has the right ingredients to make good on its promised Jinba Ittai ("rider and horse as one") driving experience.

Mazda working on lithium-ion batteries to replace lead-acid starter batteries

In the quest for ever better fuel economy, car companies are looking for every single advantage possible, no matter how small. This is evident in everything from active grille shutters to the 48-volt mild-hybrid electric assist systems like that in the new Ram 1500. For Mazda, the latest target for potential efficiency gains is the lowly 12-volt starter battery. The company announced that it is partnering with two other companies, ELIIY Power and Ube Industries, to develop a lithium-ion starter battery that would be used on mainstream models in place of conventional lead-acid units. Mazda plans to have them ready for use by 2021. The advantage here would be that 12-volt lithium-ion batteries would be much smaller and lighter than the lead-acid ones they replace. And lighter cars don't need as much fuel to move around. Plus, as an added benefit, making cars lighter also often makes them faster and better handling. This is why companies such as Lotus and Porsche have offered optional lithium-ion 12-volt batteries for some lightweight sports cars. A potential downside to the use of these batteries is increased cost. Lead-acid batteries from your local parts store will run you between $100 to $150. AGM batteries could be between $200 and $300. As for lithium-ion batteries, Lotus introduced the option on the Evora 400 in 2016, and the option cost $1,690. Odds are that a company such as Mazda won't be absorbing all those costs, meaning that the cost of these future Mazdas could increase with a change from lead-acid to lithium ion. Related Video:
