Drop-top driving gets even better in 2007, thanks to the Mazda MX-5 Miata's new power retractable hardtop, which raises and lowers at the push of a button. The lightweight, three-section hardtop folds and stows itself into the MX-5 Miata's truck in just 12 seconds. Better still, Mazda notes that the hardtop, when stowed, does not compromise trunk space. A new Z-fold soft convertible top is also available. Now in its 16th year, the MX-5 Miata roadster continues the tradition of the two-seat roadster that originated with the classic British roadsters of the 1950s and '60s. The MX-5 Miata received a complete redesign in 2006, so other than the addition of the power hardtop, Mazda didn't make any major changes to the Miata for 2007. The MX-5 Miata is available in SV, Sport, Touring, and Grand Touring trim packages, with the power hardtop available on the Sport, Touring, and Grand Touring packages (all three packages are also available with the soft top). Power is provided by a 166-horsepower 2.0-liter four-cylinder with variable valve timing. A five-speed manual transmission is standard on the SV and Sport packages, while the Touring and Grand Touring versions get a six-speed manual. A six-speed automatic is optional with some packages. Also available is a Sport AT six-speed shifter, which can be controlled with either the shift knob or shift panels behind the steering wheel. Standard features for the rear-wheel-drive Miata include power windows, dual front and side airbags, power exterior mirrors, a glass rear window, anti-lock brakes, and a CD player. The Sport package adds air conditioning, while the Touring package adds power door locks, and the Grand Touring package adds leather seats, among other features. Early reviews for the 2007 MX-5 Miata have been generally positive, with the Miata's styling, interior design, acceleration, sportiness, and responsive handling drawing positive comments. On the downside, some drivers noted that the Miata's fuel mileage is not as good as expected.
