A risky venture in 1989 yet the shrewdest move for Mazda, this little Japanese roadster eventually chalked up 700,000 sales worldwide as it capped the Guinness Book of World Records world's best-selling sports car. Mazda is now looking toward the 1 million mark with the third-generation, 2006 MX-5.

The 2006 Miata will make its debut in Canada this August, It will be called the MX-5 Miata for a year or two, but Canadians and Americans can look for the Miata name to disappear after that, unifying the vehicle as an MX-5 worldwide.

It will be wider and more muscular in appearance with a prominent front and rear fender arches that recall the same style on the flashy RX-8; a more smoothly tapered nose and tail; the inboard placement of the headlights and taillights; and a particularly appealing revised grille.

The body structure is now 47 per cent more rigid, and has a lower center of gravity that should enhance handling. One unusual feature of the '06 Miata is the convertible roof, which, is a manually raised and lowered metal top.

A stiffer unibody structure serves as the chassis foundation, with a double-wishbone suspension in front and multilink system in the rear. Larger front-brake rotors and 25-percent-stiffer calipers help extract optimal stopping distances from the four-wheel single-piston-caliper disc system.

Power is enhanced with its new 2.0-litre engine rated at around 160 hp and balance will be improved by moving the engine 135 mm rearward to create 50:50 front-to-rear weight distribution.

A newly developed six-speed manual transmission will be available, along with the standard five-speed manual. An available six-speed automatic transmission can be manually controlled by the shift lever and by steering wheel-mounted paddles.
