Mazda MX-5 Miata Mazdaspeed Complete Report

The biggest change for the Miata since its 1989 inception came in mid-2004 with the introduction of the 178-hp, turbocharged Mazdaspeed MX-5. Speed now joins lively handling as part of the Miata's timeless appeal. The 1.8-liter four-cylinder engine makes peak horsepower at 6000 rpm, and 166 lb-ft of torque at 4500 rpm. That's 25 percent more horsepower and 33 percent more torque than the naturally aspirated Miata, which remains unchanged for 2005. A five-speed manual transmission is standard on base and LS Miatas, with an automatic available on both.
