The Mazda MX-5 Miata, celebrated for its nimble handling and driver-focused dynamics, relies on a range of efficient and responsive powertrains. Understanding what engine does a miata have is essential for anyone considering purchase or modification, as the powerplant defines the character of the driving experience.
Evolution of the Miata Engine Lineup
Since its introduction in 1989, the Miata has featured a succession of distinct powerplants, each refined to balance performance with reliability. The original model introduced the world to a spirited, naturally aspirated four-cylinder that set the template for modern roadsters. Over the decades, advancements in technology have led to increased horsepower, improved fuel efficiency, and smoother operation while retaining the engaging feel enthusiasts crave.
NA Model Series Engines
1.8-Liter BP Engine
The first-generation models, often referred to as NA, were powered by the 1.8-liter BP engine. Producing around 116 horsepower, this dual overhead cam unit was praised for its linear power delivery and redline buzz. It formed the mechanical backbone of the classic Miata and remains a popular platform for tuning and swaps.
1.8-Liter BP-ZE Engine
In later NA variants, the BP evolved into the BP-ZE, incorporating variable valve timing on the intake side. This update helped boost power to 123 horsepower while improving efficiency. The refined nature of this engine cemented the Miata’s reputation for delivering precise, communicative performance.
NB Model Series Engines
1.8-Liter BP Engine
Carrying over from the NA series, the 1.8-liter BP continued in the NB generation with minimal changes. It provided a familiar driving experience, characterized by eager revs and a linear throttle response that enthusiasts appreciated for weekend drives and spirited back-road runs.
1.8-Liter BP-4WDE Engine
For markets with stricter emissions regulations, the NB featured the BP-4WDE variant. Though power output remained similar, this version was engineered to meet global standards without compromising the engaging nature of the Miata’s chassis.
NC Model Series Engines
2.0-Liter MZR Engine
With the introduction of the NC generation in 2005, Mazda transitioned to the 2.0-liter MZR engine. Delivering 150 to 166 horsepower, this all-aluminum unit offered improved torque across the rev range. The NC chassis complemented the powerplant with a stiffer structure, enhancing overall handling dynamics.
2.0-Liter MZR with DISI Turbo
The Mazdaspeed3 Miata variant introduced a turbocharged version of the MZR, producing 200 horsepower. This performance-oriented model showcased how forced induction could elevate the Miata beyond its naturally aspirated roots, providing brisk acceleration while retaining the car’s agile character.
ND Model Series Engines
2.0-Liter Skyactiv-G Engine
The current ND generation marked a significant leap with the Skyactiv-G 2.0-liter engine. Generating 181 horsepower and 151 lb-ft of torque, this unit features direct injection and a high compression ratio. The result is a modern powerplant that offers both efficiency and engaging responsiveness, aligning with contemporary emissions standards.
1.5-Liter Skyactiv-G Engine
In certain international markets, a 1.5-liter variant of the Skyactiv-G is offered. Producing 161 horsepower, this compact unit provides a lighter alternative that enhances agility. It demonstrates Mazda’s commitment to optimizing displacement without sacrificing the spirited nature that defines the Miata.
