FH6 Mazda MX-5 Miata Generations — NA vs NB vs NC vs ND

The Mazda MX-5 Miata is the most successful roadster ever built, with over 1 million sold since 1989. Four generations span 36 years, each with the same core philosophy: lightweight, rear-wheel drive, 50/50 weight balance, and an affordable price. Forza Horizon 6 includes the modern ND generation in two trims (ND2 soft-top and RF hardtop), and the older NA, NB, and NC generations appear in various Forzathon events and the Auction House. This guide covers the per-generation character, the chassis evolution, and which Miata to pick for the playstyle you actually have.

1. The Miata Philosophy — Lightweight RWD for the Driver

The MX-5 Miata’s defining characteristic isn’t power, grip, or luxury — it’s balance. Every generation weighs under 1,200 kg, sits on a near-50/50 weight distribution, and has a manual transmission as standard. The Miata is the anti-supercar: it doesn’t try to be the fastest, the grippiest, or the most powerful. It tries to be the most fun at legal road speeds, and it succeeds.

What this means for tuning: the Miata is the most chassis-limited platform in the game. You can’t tune around a heavy platform with power; the Miata’s advantage is its low mass and balanced chassis, so the right modifications protect those characteristics rather than overcome them. Adding weight, aggressive aero, or excessive power all hurt the Miata; the platform rewards setup discipline over power.

2. The Generations at a Glance

NA (1989-1997) — The Original

The NA Miata is the purest expression of the platform. The 1.6L or 1.8L naturally aspirated four-cylinder, dual overhead cam, 116-128 hp depending on the market. The chassis is the lightest of all generations (~960 kg). Pop-up headlights, no power steering (early models), no ABS. The NA is the most popular drift platform in the world thanks to its light weight, simple chassis, and abundant aftermarket.

In FH6: The NA appears in Forzathon events and the Auction House. A-class 600-700. Best used for drift, touge, and charm builds. The NA is the most popular Miata for engine swaps — K-series Honda swaps, 2JZ swaps, and even LS swaps are common community builds. The NA rewards chassis setup over power; the stock engine is enough for most B-class events.

NB (1998-2005) — The Refined Original

The NB Miata fixed the NA’s biggest weakness: power. The 1.8L engine produces 140-160 hp depending on the market, with variable valve timing. The chassis is slightly stiffer, the interior is more refined, and the styling is more modern. The NB is the most balanced Miata for mixed-use driving.

In FH6:The NB appears in Forzathon events and the Auction House. A-class 650-750. The NB is the most versatile Miata — it drifts well, road races well, and is the most comfortable for daily driving in-game. The NB’s chassis is more progressive than the NA, which makes it more forgiving for new drifters.

NC (2005-2015) — The Heaviest Miata

The NC Miata is the most controversial generation. The 2.0L MZR engine produces 170-200 hp. The chassis is the heaviest (~1,100 kg), the wheelbase is longer, and the styling is more modern. The NC is the most comfortable Miata and the most refined on the highway, but the extra weight dulls the platform’s defining balance.

In FH6: The NC appears in Forzathon events and the Auction House. A-class 700-800. The NC is the best compromise Miata — it has the power for highway merging, the comfort for long drives, and the chassis for occasional track days. The NC is the least popular for drift but the most popular for road trips and touring events.

ND (2015-present) — The Modern Revival

The ND Miata returned to the platform’s roots: lightweight, balanced, RWD. The 2.0L Skyactiv-G engine produces 181 hp in the ND2 trim. The chassis is the lightest of the modern Miatas (~1,060 kg). The styling is a clear homage to the NA. The ND2 is the most refined Miata of all — the steering is electric but well-weighted, the suspension is compliant but controlled, and the engine is the most responsive.

In FH6: The ND2 is the most competitive Miata at A-class 800-850. The 2020 ND2 soft-top and the 2023 ND RF (retractable fastback hardtop) are both in the game. The ND2 is the best Miata for road racing in FH6 thanks to its higher stock PI (752), refined chassis, and responsive engine. The ND RF adds a hardtop for ~30 kg of weight but maintains the same chassis balance.

3. Picking the Right Miata for Your Playstyle

Drift — NA or NB

The NA is the most popular drift platform in the world. Its light weight, simple rear suspension, and abundant aftermarket make it the easiest Miata to set up for sustained drift angles. The NB is a close second — the slightly more progressive chassis makes it more forgiving for new drifters, but the heavier front end reduces ultimate drift angle.

Road Racing — ND2

The ND2 is the most competitive road racing Miata. Its 2.0L Skyactiv-G engine has the highest stock output, its chassis is the most refined, and its electronics (traction control, stability control) are the most tunable. At A-class 800, the ND2 is genuinely competitive against more powerful RWD cars — it’s not the fastest, but it’s the most consistent.

Touge / Mountain Pass — NB

The NB is the best Miata for mountain pass driving. Its progressive chassis responds well to weight transfer, its 1.8L engine has enough power for sustained climbs, and its comfort is good for long drives between passes. The NB is the Miata that’s most fun to drive on the Akina Pass or Hokkaido mountain roads in FH6.

Daily Driver / Touring — NC or ND RF

The NC and the ND RF are the most comfortable Miatas. The NC is the most refined on the highway and the most spacious interior; the ND RF adds a hardtop for weather protection and slightly quieter cabin. Both are excellent choices for Horizon Life cruising, road trips, and Car Meet showcasing.

4. Tuning Considerations Across Generations

The Miata is the most chassis-limited platform in the game, which means tuning discipline matters more than power. Three rules apply across all generations:

Weight Reduction — Be Conservative

• Stage 1 is the sweet spot for most Miata builds. Stage 2+ removes structural rigidity and makes the chassis nervous over bumps.
• NA and NB are the most weight-sensitive — these generations are already light, so over-reducing weight loses the platform’s defining characteristic.
• NC benefits from Stage 2 weight reduction because it’s the heaviest generation. Stage 3 is rarely useful.

Tires — Match to Purpose

• Drift — use Street or Sport tires with rear-biased tire width (235 F / 245 R or wider rear). The Miata’s light weight means you don’t need Semi-Slick tires for drift.
• Road Racing — use Semi-Slick tires. Even width (245 F / 245 R) is fastest; the Miata’s balanced chassis doesn’t benefit much from aggressive stagger.
• Touge — use Sport tires. Sport tires last longer than Semi-Slick and provide enough grip for sustained mountain passes.

Engine — Don’t Over-Swap

• Stock engine — for B-class and A-class below 800, the stock engine is enough. The Miata’s chassis balance matters more than power.
• Forced induction — for A-class 800 and above, add a turbo or supercharger. The Miata’s stock internals handle up to 250 whp reliably.
• Engine swap — for S1-class and above, swap to a 2JZ or K-series Honda. These swaps are the most popular Miata community builds and produce 600+ hp on stock internals.

5. Common Miata Tuning Mistakes

1. Over-reducing weight on the NA. The NA is already light. Stage 3+ weight reduction makes the chassis too nervous over bumps. Stage 1 is enough.
2. Adding aggressive aero to a road racing build. The Miata is too light for big wings to work. The added weight and drag hurt more than the downforce helps.
3. Using Semi-Slick tires for drift. Semi-Slick tires make drift harder because they have more grip. Use Street or Sport tires for drift builds.
4. Swapping the engine before mastering the stock one. Engine swaps change the chassis balance dramatically. Master the stock Miata first, then swap.
5. Picking the wrong generation for the purpose. The NC is not a drift car. The NA is not a highway cruiser. Match the generation to the playstyle.
