Understanding the engine is crucial, whether you're a seasoned owner or just dreaming of owning one. So, let's get started, guys!

The Heart of the Miata: Engine Options Through the Years

The Mazda Miata, known for its lightweight design and nimble handling, has seen a few different engines over its production years. Each engine offers a unique driving experience, contributing to the Miata's iconic status. Let's break down the engine options by generation.

First Generation (NA): 1.6L and 1.8L Engines

The original Miata, the NA, debuted with a 1.6-liter four-cylinder engine. This engine, while not the most powerful, provided a rev-happy and engaging driving experience that perfectly matched the car's character. In 1994, Mazda upgraded to a 1.8-liter engine, offering more power and torque. Here’s a closer look:

• 1.6-Liter Engine: This engine produced around 115 horsepower and 100 lb-ft of torque. It was known for its reliability and eagerness to rev. The 1.6L engine made the NA Miata a blast to drive on winding roads.
• 1.8-Liter Engine: The upgrade to 1.8 liters brought approximately 130 horsepower and 110 lb-ft of torque. This increase in power made the Miata quicker and more responsive, enhancing the overall driving experience. The 1.8L engine maintained the Miata's reputation for being fun and engaging.

The NA Miata, especially with the 1.8-liter engine, remains a favorite among enthusiasts. Its simplicity and direct driving feel make it a classic roadster. If you're considering an NA Miata, both engines offer a great experience, but the 1.8-liter provides a bit more punch.

Second Generation (NB): Continuing the 1.8L Legacy

The second-generation Miata, the NB, continued with the 1.8-liter engine, refining it for improved performance and efficiency. While the displacement remained the same, Mazda made several enhancements to boost power and responsiveness. Here’s what you need to know:

• Enhanced 1.8-Liter Engine: The NB Miata's 1.8-liter engine produced around 140 horsepower. This increase came from improved engine management and other refinements. The NB Miata felt more refined and powerful than its predecessor.
• Improved Torque: Torque was also improved, making the NB Miata more tractable in everyday driving situations. Whether you're cruising around town or attacking your favorite backroad, the NB's engine delivers a satisfying experience. The enhanced torque made the car feel more responsive and easier to drive.

The NB Miata represents a step forward in terms of performance and refinement while retaining the essential Miata character. Its engine is more powerful and more efficient than the NA's, making it a great choice for those looking for a slightly more modern classic.

Third Generation (NC): 2.0L Engine for Added Punch

The third-generation Miata, the NC, marked a significant departure with a larger 2.0-liter engine. This engine provided a substantial increase in power and torque, transforming the Miata's performance. Here's a detailed look:

• 2.0-Liter Engine: The NC Miata's 2.0-liter engine produced around 170 horsepower. This was a significant jump from the previous generations, offering a more thrilling driving experience. The NC Miata felt significantly faster and more powerful than the NA and NB models.
• Increased Torque: The 2.0-liter engine also delivered a healthy dose of torque, making the NC Miata feel strong and responsive at any speed. Whether you're accelerating out of a corner or cruising on the highway, the NC's engine provides ample power. The increased torque made the car more versatile and enjoyable in a wider range of driving situations.

The NC Miata is often praised for its improved performance and more comfortable ride. The 2.0-liter engine gives it a level of performance that the earlier generations couldn't match. If you're looking for a Miata with a bit more grunt, the NC is an excellent choice.

Fourth Generation (ND): Skyactiv Technology and Refinement

The fourth and current generation Miata, the ND, features Mazda's Skyactiv technology, focusing on efficiency and performance. The ND Miata offers a refined driving experience with two engine options:

• 1.5-Liter Engine: Available in some markets, the 1.5-liter engine provides a rev-happy and efficient driving experience. While not as powerful as the 2.0-liter, it maintains the Miata's fun-to-drive character. The 1.5L engine is known for its smooth power delivery and excellent fuel economy.
• 2.0-Liter Engine: The 2.0-liter Skyactiv engine is the primary choice for most markets. It delivers around 181 horsepower and offers a perfect balance of performance and efficiency. This engine incorporates advanced technologies like direct injection and variable valve timing, resulting in impressive power and fuel economy. The 2.0L engine makes the ND Miata a joy to drive, whether you're on a twisty road or a long highway.

The ND Miata is celebrated for its lightweight design, responsive handling, and efficient engines. The Skyactiv technology enhances both performance and fuel economy, making it a modern sports car that stays true to the Miata's roots. The ND Miata is a testament to Mazda's commitment to building fun and engaging sports cars.
