The Reimagined Roadster: A Philosophy of Pure Driving
Before the Miata arrived, the classic British roadster, known for its unfiltered driving experience, had largely faded into history, plagued by reliability issues and safety concerns. Mazda saw an opportunity not to copy, but to reimagine that spirit. The result was the NA Miata, a car that distilled the essence of open-top motoring into a reliable, affordable, and incredibly fun package.
Its design was intentionally simple, drawing inspiration from legendary lightweight sports cars like the Lotus Elan. With its iconic pop-up headlights, short overhangs, and graceful lines, the Miata exuded an immediate sense of playfulness and purpose. But beneath that friendly exterior lay a meticulously engineered machine: a front-engine, rear-drive configuration that prioritized balance and driver engagement above all else. This wasn't a car about raw power; it was about precision, communication, and the sheer joy of the drive.
Under the Hood: The Evolution of Power and Punch
From its inception, the Miata’s powertrain was designed for responsiveness, not outright speed. The goal was to provide a peppy, rev-happy engine that complemented the car's lightweight chassis.
The Original 1.6-liter (1990-1993)
The first U.S. models, arriving in 1990, were equipped with a 1.6-liter DOHC 16-valve four-cylinder engine. This spirited little mill produced a respectable 116 horsepower and 100 pound-feet of torque. Paired exclusively with a slick-shifting five-speed manual transmission initially, it allowed the 2,182-pound roadster to achieve 0-60 mph in around 9.0 seconds, topping out at 116.8 mph. A four-speed automatic transmission became an option later in the first model year, though it came with a slight power reduction to 105 hp.
A key detail for owners and prospective buyers: both the 1.6-liter and subsequent 1.8-liter engines utilize a timing belt. Mazda recommends a service interval of 60,000 miles, and crucially, both are non-interference engines. This means that if the timing belt were to fail while driving, the valves would not collide with the pistons, saving you from a potentially catastrophic engine repair. It's a testament to Mazda's thoughtful engineering.
The Punchier 1.8-liter (1994-1997)
For the 1994 model year, Mazda addressed calls for a bit more grunt by upgrading the engine to a 1.8-liter four-cylinder. This brought a welcome boost in output to 128 horsepower and 110 lb-ft of torque. This enhancement made the Miata feel even more eager, shaving a bit off the 0-60 mph time and improving overall driveability.
The power didn't stop there. In 1996, the 1.8-liter engine received another slight bump, reaching 133 horsepower. This iterative improvement further refined the car’s performance, reducing the 0-60 mph sprint to approximately 8.7 seconds and raising the top speed to 118 mph. While still not a drag racer, these power figures were perfectly matched to the Miata’s lightweight, balanced chassis, ensuring that every horsepower felt significant.
The Chassis: A Masterclass in Balance and Agility
The true genius of the NA Miata lies in its chassis. This wasn't just a car; it was a driving lesson on wheels, teaching enthusiasts the importance of balance, feedback, and mechanical grip over brute force.
A Foundation of Precision
Right from the start, Mazda engineered the NA Miata for dynamic excellence. Its dimensions – 155.4 inches long, 89.2-inch wheelbase, 65.9-inch width – contributed to its nimble character. Critically, it boasted a dead-even 50:50 front-to-rear weight balance, a holy grail for handling. The battery and spare tire, for instance, were carefully placed in the trunk to achieve this optimal distribution.
The suspension setup was sophisticated for its class: double-wishbone independent suspension at all four corners, complemented by front and rear anti-roll bars. This provided excellent wheel control and a supple, yet communicative, ride quality. Standard 14-inch wheels fitted with lightweight Bridgestone 185/60R14 SF-325 tires offered ample grip without being overly wide, maintaining the car's light steering feel.
Braking was handled by disc brakes all around (9.3-inch front, 9.1-inch rear), providing confident stopping power. Anti-lock brakes (ABS) became an optional extra in the second model year, adding a layer of safety without compromising the direct feel.
The Power Plant Frame (PPF): A Structural Game-Changer
Perhaps one of the most innovative and often overlooked components of the NA Miata is its aluminum Power Plant Frame (PPF). This structural brace directly connects the transmission to the differential, creating a rigid backbone that virtually eliminates drivetrain flex. The result is a more direct, immediate feel from the throttle, as power is transferred to the rear wheels with minimal loss or delay. It's a testament to Mazda's commitment to engineering a car that feels as connected as possible to the driver.
Enhanced Safety and Traction
With the 1994 engine upgrade, Mazda also introduced several safety enhancements, including a cross-body brace for improved rigidity, door anti-intrusion beams for side-impact protection, and a passenger-side airbag (driver's side airbag was already standard). These updates ensured the Miata kept pace with evolving safety standards without detracting from its core character.
The optional limited-slip differential, crucial for maximizing traction out of corners, also saw an upgrade. Early models often featured a viscous-type LSD, which was effective but could sometimes fade with heavy use. In 1994, this was largely replaced by a Torsen-type limited-slip differential, known for its more consistent and predictable performance, making the Miata even more engaging for spirited driving.
Special Editions and Packages: More Ways to Enjoy the Roadster
Throughout its production run, Mazda offered various special editions and performance packages, catering to different tastes and desires. These often featured unique paint colors, interior appointments, and sometimes performance-oriented upgrades.
One notable offering was the M Edition, produced from 1994 to 1997. These limited-run models typically sported unique exterior colors, special wheels, and upgraded interior features like Nardi steering wheels and tan leather seats, offering a more luxurious take on the Miata experience.
For the performance purists, the R Package was the answer. This option packed firmer springs, revised dampers, stiffer anti-roll bars, and sometimes aerodynamic elements like front and rear spoilers. The R Package Miatas were designed for drivers who wanted an even sharper, more track-focused machine right from the factory. While relatively rare, these performance variants are highly sought after by collectors and enthusiasts today.

The final 1997 models now command $6,350-$7,500, up from $4,300-$4,750.
If you're eyeing a special edition or an M Edition Miata, expect to pay a premium of about 20 percent. R Package cars, with their factory performance upgrades, command around a 15 percent premium. On the flip side, automatic transmission Miatas typically sell for about 15 percent less than their manual counterparts, a reflection of the enthusiast preference for the engaging five-speed.
What to Look For: Navigating the Buying Process
When you're out searching for your NA, thorough inspection is key. Here's what to prioritize:
- Rust: This is the NA Miata's Achilles' heel. Pay very close attention to the rocker panels, particularly near the jacking points and behind the front wheels. Blocked top drains can channel water into these areas, causing rust from the inside out. Inspect wheel arches, floor pans, and the trunk for any signs of corrosion.
- Modifications: Be wary of poorly executed modifications. While some aftermarket parts are beneficial, others can indicate a hard life or shoddy workmanship. Look for original parts where possible, or well-documented, professional upgrades.
- Soft Top Condition: Check for tears, rips, and clarity of the plastic rear window (if not replaced with glass). The soft top mechanism should operate smoothly.
- Engine and Transmission: Listen for unusual noises, check for leaks, and ensure the engine idles smoothly. For manual transmissions, test all gears for smooth engagement and check the clutch for slipping.
- Service History: A car with a well-documented service history is always preferable, especially concerning the timing belt.
- Pop-up Headlights: Ensure both lights operate smoothly and simultaneously. Minor issues can be fixed, but it's a good negotiation point.
