Second Generation Miata: 1999-2002

The second generation Miata was a 1999 model year vehicle. This new generation car offered a more powerful engine and new styling, including a new headlight design. For the first time the vehicle featured fixed headlights, which were lighter in mass in the dynamically critical front over hang, as opposed to the first generation's retractable headlights. In addition, the plastic window in the Miata's soft top was replaced with a glass window.

The engine remained at 1.8-liters and received several updates. Power output and torque were improved to 140 horsepower with 119 lb.-ft. torque through enhancements to the intake and exhaust systems, resulting in smooth engine revving from low to high speeds and responsive acceleration with EPA mileage of 24/29 mpg. Features such as a straight intake port, a variable-inertia exhaust system and a dual exhaust manifold were incorporated. Compression ratio was raised from 9.0:1 to 9.5:1 with a raised-crown piston design. The base model could reach 60 mph in 7.9 seconds, with a top speed of 122 mph. Total weight of the second generation Miata was 2,200 pounds.

A special limited edition model was introduced in 1999 to celebrate Miata's 10th anniversary. This model ramped up performance by use of a new six-speed manual transmission, Torsen® limited-slip differential and sport-tuned suspension with Bilstein® shock absorbers. A special Sapphire Blue Mica paint with blue soft top was also offered on the 10th Anniversary model.

In 2000, the face-lifted second-generation MX-5 was launched as a 2001 model. Mazda added more horsepower, variable valve timing, a more rigid chassis and larger brakes. Additionally, 16-inch alloy wheels, a six-speed manual transmission, more aggressive styling and a host of interior improvements were available. The 2001 Miata delivered 142 horsepower and 125 lb.-ft. of torque with 23/28 mpg City/Highway fuel economy, and the compression ratio was increased from 9.5:1 to 10.0:1. With the minimum amount of options, the 2001 model weighed 2,387 pounds.
