The MX-5 Miata roadster comes in two basic configurations: a soft-top or a power retractable hardtop. Three transmissions are offered, a five-speed manual, a six-speed manual and a six-speed automatic with steering wheel mounted paddle shifters. The only engine available, a 2.0-liter, inline four-cylinder, comes in two power levels, one rated at 167 horsepower with either manual transmission, or 158 horsepower with the automatic. Standard safety equipment across the line comprises dual front airbags with passenger deactivation switch, side impact airbags, tire pressure monitoring and anti-lock brakes with electronic brake-force distribution; electronic stability and traction control is optional on the Grand Touring trim. For 2010, the SV trim was dropped from the soft-top, and the Sport trim was dropped from the hardtop.
