Pick your Underrated Miata Generation : NB vs. NC Comparison

When it comes to lightweight, affordable sports cars, few names resonate as deeply as the Mazda Miata. Introduced in 1989, the Miata became the embodiment of fun-to-drive simplicity, blending affordability with spirited performance. Over the decades, it evolved through multiple generations, each offering a distinct take on the formula while staying true to its core values.

Today, we’re comparing two standout models: the NB Miata (1999–2005) and the NC Miata (2005–2015). The NB represents the last of the analog Miatas, a purist’s dream with its lightweight construction and direct driving feel. The NC, on the other hand, embraced modernization with more power, comfort, and versatility, appealing to a broader audience. While both generations carry the Miata DNA, their driving experiences and capabilities cater to different preferences. Let’s dive in and explore what sets these two icons apart.

Why Compare the NB and NC?

The NB Miata is often celebrated as the “classic” Miata. It’s raw, analog, and delightfully simple, focusing solely on the driving experience. It stays true to the lightweight philosophy of the original NA Miata, with a slightly more refined design and performance. Enthusiasts love its hydraulic steering and double-wishbone suspension, which make it one of the most engaging cars to drive, even decades after its release.

The NC Miata marked a turning point for the series. It was the first Miata to receive significant updates in power, comfort, and technology, appealing to drivers who wanted more than a bare-bones roadster. With a larger engine, a more spacious interior, and the option of a retractable hardtop, the NC opened new doors for the Miata’s audience. This comparison isn’t just about numbers; it’s about understanding how these two cars fulfill the Miata promise in different ways.

Handling and Driving Dynamics

The Miata’s reputation for handling excellence is well-earned, and both the NB and NC carry that torch in their own ways.

NB Miata

The NB Miata’s hydraulic steering is a masterclass in feedback and immediacy. Every input is met with a corresponding response, and the driver feels completely in tune with the car. The double-wishbone suspension ensures excellent mechanical grip, making tight corners an absolute joy. However, body roll is noticeable in the stock setup, which can be a bit unnerving at higher speeds. That said, the 50:50 weight distribution provides stability, though the car’s rear can feel twitchy when pushed to its limits.

NC Miata

The NC Miata introduces electronic power steering (EPS), which, while precise, lacks the raw feedback of the NB’s system. Its wider track and improved suspension geometry give it superior stability in fast corners, making it a better choice for high-speed driving. The NC also rides more comfortably, with a softer suspension setup that absorbs bumps and imperfections with ease. While this makes it a better daily driver, it sacrifices some of the direct, playful nature that the NB offers.

Verdict on Handling

The NB is the clear choice for drivers who crave a visceral connection with the road. It’s lively, nimble, and rewards precision. On the other hand, the NC offers a more composed and stable ride, excelling on highways and sweeping curves, though it doesn’t match the NB’s pure engagement.

Power and Acceleration

Engine Performance

Under the hood, the NB and NC reflect their respective eras. The NB’s 1.8L inline-4 produces 140 horsepower and 116 lb-ft of torque, which feels lively thanks to the car’s lightweight construction (2,348 lbs). However, the engine’s mid-range power is lacking, and acceleration feels linear rather than punchy.

The NC, with its 2.0L inline-4, delivers 170 horsepower and 140 lb-ft of torque. While it’s heavier at over 2,500 lbs, the increased power and stronger torque curve more than compensate. The NC feels significantly more responsive, particularly in everyday driving scenarios where low- and mid-range torque shine.

Acceleration Comparison

• 0–60 mph:
  • NB: ~7.6 seconds.
  • NC: ~6.7 seconds.
• Mid-Range Power: The NC pulls ahead here, with a more potent engine that makes highway overtaking effortless.

Transmission Comparison

The NB features a 5-speed manual with short gearing that keeps the engine in its sweet spot. However, it can feel a bit busy during highway driving. The NC upgrades to a 6-speed manual with a taller 6th gear, making it far more comfortable for long trips. Both transmissions are a joy to use, with smooth shifts and precise engagement.

Braking and Suspension

NB Miata

Braking in the NB requires skill, especially in early models without ABS. The brakes themselves are adequate, but the car’s light weight makes it more forgiving. The suspension, while soft, delivers excellent feedback and can easily be upgraded to enhance performance.

NC Miata

The NC benefits from larger brakes with ABS as standard, offering better stopping power and fade resistance. Its stock suspension prioritizes comfort over outright performance, making it less engaging but more composed under heavy braking.

The NB is a raw, engaging platform that rewards experienced drivers. The NC, meanwhile, is safer and more forgiving, particularly for novices or those driving at the limit.

Practicality and Comfort

When it comes to daily usability, the NC is a clear winner. Its interior is more spacious, with wider seats and better ergonomics. Features like the optional retractable hardtop improve weather protection and security, making it a more versatile choice. The NB’s interior is minimalist, with limited amenities and a cabin that can feel cramped on long drives.

Fuel economy is comparable, with the NB averaging 26–30 mpg and the NC slightly lower at 24–28 mpg due to its increased weight and power.

Aftermarket Potential

Both the NB and NC are highly modifiable, but the NB stands out for its affordability and simplicity. It’s a favorite for track enthusiasts, with endless options for suspension, brakes, and engine upgrades. The NC’s aftermarket scene is growing, and it shares some components with the RX-8, making it an excellent platform for turbocharging or serious suspension tuning.

The NB and NC Miatas excel in different areas, making them appealing to distinct audiences. The NB is the car for purists, offering an unfiltered, analog driving experience that’s hard to replicate. The NC, on the other hand, is a modern, versatile sports car that blends the Miata’s core philosophy with everyday usability and refinement.

Whichever you choose, you can’t go wrong. Both cars embody what makes the Miata legendary: lightweight fun, driver engagement, and endless smiles behind the wheel.
