The Mazda Miata has long been celebrated as one of the most engaging sports cars ever built, and one of the most common questions from both prospective buyers and enthusiasts centers on its performance. Understanding the Mazda Miata horsepower by year is essential to appreciating how this iconic roadster has evolved since its introduction in 1989, with each generation bringing distinct improvements in power, efficiency, and driving dynamics.
First Generation (NA) – 1989 to 1997
The original NA generation established the Miata’s reputation for nimble handling and accessible power. Early models from 1989 through 1990 produced 116 horsepower from a naturally aspirated 1.6-liter inline-four, providing a lively and responsive driving experience. For the 1993 model year, the introduction of the M-Edition brought a slight bump to 123 horsepower, paired with distinctive styling updates that signaled Mazda’s commitment to performance variants. By the time the first generation concluded, the base model settled at 121 horsepower, demonstrating a balance of reliability and spirited output that defined the era.
