Probably because forced induction goes against the recipe for a bare bones, 'no frills' sports car. Re: the 3.7L that ruins the Miata's 50/50 weight distribution in a big way, likely drives the price way up, and again nullifies what the Miata stands for.

Let me present to you the Curtiss Wright Aircar:

Italdesign Machimoto. All the disadvantages and discomforts of a motorbike, none of the advantages.

1957 Aurora ESV. "The prototype had a fiberglass body over a largely wooden structure built on the salvaged chassis of a 1953 Buick, which was not adequately tested before the scheduled public unveiling in 1957 and broke down 15 times on the way to the press conference, requiring towing to 7 different garages; mainly…

It was only a quarter of million dollars and the 12 coats of hand rubbed lacquer would hold up forever! (I can't be too evil ... I love these things. They are a design icon of the eighties no matter how insanely far they at one time has depreciated.)

The GM EV1

The Dymaxion Car.

Hello there.

Any kind of flying car. I cannot see them ever becoming feasible. So many people can barely drive on regular roads. It's going to be even worse in the air.

Don't hate. Be honest. You know this car was crap.

Chevy Volt

But even I realize that they run on a fuel source that will not last forever and is largely located in a politically unstable part of the world we have no business being embroiled in.

I know what the least cool in-car graphic is:

But here's the thing. On any other car — a sedan, a minivan, an SUV, even a high-end performance car — such an interior on 2014 model would count as strikes against it. But on the Miata, it all just works. The interior is simple, effective, easy to figure out, and never distracts you from driving, and that's the…

Its just so badass.

I forget which show I saw this information on, but my understanding is that when a car is painted they don't take the time to align the carbon weave perfectly as evidenced by this quote by Car and Driver:

Will sell? As in, future tense? Am I out to lunch, or hasn't the Huayra been available for sale for a while now?

Open wheel hillclimb = pucker factor 10. Especially with that camera angle, the wheels seemed about to hit the stuff at the sides of that narrow course every other moment.

That looks like the old school Lego Guy Helmet!
