Mazda MX-5 Miata Spyder Concept - SEMA Auto Show

Considering that any car called a "spyder" is invariably an open-top machine and probably a two-seater, then making an existing roadster into a spyder means something extra needs to go on. In the case of this Mazda MX-5 Miata Spyder - on display at the 2011 SEMA show - the "something extra" consists of an elegant cloth roof stretched over a double-bubble decklid.

This is a collaboration between MNAO Design and Magna Car Top Systems and has the happy upshot of making the world's most popular roadster (it's official; it's in the Guinness Book of World Records) seem a little more exclusive, with an even lower roofline that doesn't affect headroom.

Although it's a spyder, there's more to this car than less of a roof. Instead of using plain old gasoline, the 2.0-liter four-cylinder engine here runs on isobutanol, a fuel created from cellulose and which Mazda has used successfully in its motorsport program. Following a sporty theme, the lowered coilover suspension comes from Mazdaspeed's inventory. A more aerodynamically efficient front fascia has been installed, and the stock wheels replaced by 17-inch light-alloy wheels wearing performance tires. In the interests of lightness, the battery is a racing model from Braille, using lithium-ion technology.

SInce this is a concept car, at least that gave Mazda the leeway to splash out somewhat and fit black leather upholstery into the cabin, while a Mazdaspeed short-throw gear shifter provides the finishing touch. Chances are that a production model might end up with a higher price than most people would be prepared to pay for an MX-5 Miata. Which is a shame, because this spyder would look good on the streets.
