Our Mazda MX-5 Miata has the best engine bay in the business

One of the things that's really disappointing about modern cars is how they all hide their technology under a proverbial bushel. You pop the hood, and nine times out of 10, you're faced with some amount of black plastic hiding the functional bits. On some cars the plastic covers the bare minimum to have a "presentable" engine. Others have every tank, hose, wire and screw buried under a layer of smooth plastic. Few exemplify this practice better than engine bay of the current Lexus LS 460, seen below. If Lexus was this embarrassed about its engine, maybe it should have simply bolted the hood shut. However, like with weight gain and power creep, our fourth-generation Mazda MX-5 Miata bucks the plastic trend. Lift the aluminum hood of the little roadster, and you travel back in time more than a decade. (See the gallery up top.) Only one bit of decorative plastic is in sight, and it proclaims the car's Skyactiv technology and hides some of the wires leading to the ignition coils. Otherwise, nothing else is obscured. The shock tower braces, manifolds, battery terminals, the whole shebang is all right there for you to see. What's particularly amazing is that it all looks good. Even in some cars that eschew plastic covers, it's no guarantee of an attractive engine bay. We just had a new Honda Civic Sport hatchback (seen immediately above), and while it doesn't sport a plastic engine cover, you can see from the photo that it's not particularly attractive with tubes and cables snaking every which way. But in the Miata, the hoses and wires are kept to a minimum, and the ones that are there are arranged in a way that isn't haphazard or tangled. Then, in the middle, there's the clean, simple aluminum cam cover as the gleaming centerpiece, similar to those of the first- and second-generation cars. As the owner of a '99 Miata, this detail in particular gives me the warm fuzzies. The fully exposed engine bay fits with the Miata's personality. The car is very straightforward, it features just the absolute minimum of style and comfort additions, and is highly accessible. I would say the Miata's engine bay is the window to its soul, if driving it didn't offer a clearer picture. Related Video:

Mazda CEO says rotary not viable, so don't look for a new one

We have some very sad news to report, rotor-heads fans: Don't expect a new rotary-powered vehicle anytime soon. This comes straight from Masamichi Kogai, the CEO of Mazda, which is the only company to ever market a commercially successful rotary-powered automobile in the world. The issue, as it has pretty much always been, is environmental.
While the Wankel rotary engine does indeed make a lot of power in a small, lightweight package, it does so while burning lots of fuel and emitting lots of noxious gases into the atmosphere, at least when running on gasoline. And that means the rotary engine will likely only ever be able to power niche vehicles. And that, in turn, means that it is very difficult to turn a profit on vehicles with rotary engines, particularly for a small automaker like Mazda.
"It has to be a viable commercial proposition. If we are going to adopt it, it has to be a product that can generate at least sales of 100,000 units a year. We have to be able to achieve a profit," said Kogai in an interview with Automotive News. Mazda sold 56,203 RX-7 models in the United States (the automaker's biggest market) in 1986. Sales of the RX-8 peaked in 2004, its first full year on the market, with just 23,690 units.

Mazda planning more powerful MX-5?

The new Mazda MX-5 will be available with a 1.5-liter four with 129 horsepower or 2.0-liter with 155. And while either engine may seem a tad on the small side for a sports car, they keep perfectly in line with what the Miata is all about. That doesn't mean, however, that more powerful options aren't under consideration. Speaking with Motoring.com.au at the launch of the new MX-5, Mazda's global PR chief Kudo Hidetoshi revealed that two options are under consideration. One would be a larger engine, and the other a turbocharged version of the existing 2.0. The former option would deliver the extra punch while keeping things naturally aspirated and free from turbo lag, but could throw off the weight balance Mazda has worked so hard to preserve. The more likely option, then, would be the turbocharged route that would allow the Zoom-Zoom brand to keep the roadster light and nimble, while still delivering an extra boost. Neither would be without its challenges, but if overcome, the resulting high-performance model could be sold as a Mazdaspeed model in some markets and as an MPS version in others. And, even if such a performance roadster were to get the go-ahead for production in some markets, there's no guarantee that it will be sold in the United States. Here's hoping. Related Video:
