ND1 vs ND2 vs ND3

The ND MX-5 has run since 2016, and enthusiasts split it into three informal phases. Mazda never called them ND1, ND2, and ND3 (the badge says “MX-5” on all of them), but the changes between them are real enough that the shorthand stuck. Here is what each phase changed and which one is worth chasing.

The short version

ND1 (2016-2018): the original 2.0-liter, 155 hp at 6,000 rpm, 148 lb-ft, 6,800 rpm redline. Tilt-only steering column.
ND2 (2019-2023): revised 2.0, 181 hp at 7,000 rpm, 151 lb-ft, redline raised to 7,500 rpm. Telescoping steering column added. Mid-run, the 2022 model year added Kinematic Posture Control.
ND3 (2024+): new 8.8-inch infotainment, an asymmetric limited-slip differential, retuned electric steering, DSC-Track mode, and exterior/lighting updates. Same 181 hp 2.0.

Mechanically, the big jump is ND1 to ND2. The ND3 changes are mostly the cabin and chassis electronics, not the engine.

ND1: 2016-2018

The launch car. The 2.0-liter Skyactiv-G makes a quoted 155 hp at 6,000 rpm and 148 lb-ft, with a 6,800 rpm redline. (Pre-launch estimates floated higher numbers, but the US car shipped at 155.) The 1.5-liter sold in other markets never came to the US.

The car most people fell for. It is light, it steers honestly, and the early cars are now the cheapest way into a clean ND. The two ergonomic gripes that follow the ND1 everywhere: the steering column tilts but does not telescope, so taller drivers sit farther from the wheel than they’d like, and the seats are fixed-back with limited travel.

A Brembo/BBS package appeared during the ND1 run (commonly cited from the 2017 model year) bundling front Brembo calipers and BBS wheels. The Recaro seats came later, with ND2.

ND2: 2019-2023

This is where the engine got interesting. For 2019 Mazda reworked the 2.0-liter rather than replacing it: lighter internals, a revised cylinder head, larger intake and exhaust valves, and revised intake/exhaust routing. The result is 181 hp at 7,000 rpm and 151 lb-ft, with the redline raised to 7,500 rpm.

The way that power arrives matters. Below roughly 6,000 rpm the ND1 and ND2 curves are nearly identical — the ND2’s extra 26 hp lives almost entirely in the top ~1,500 rpm that the ND1 didn’t have. Flyin’ Miata and others have made the point that if you short-shift, you may never feel the difference; the gain shows up when you wring it out, which is exactly where track and autocross drivers spend their time. The higher redline also changes how you use the gears on a given corner.

The other genuinely useful ND2 change is small and unglamorous: a telescoping steering column. Combined with the tilt that was already there, it fixes the ND1’s main driving-position complaint and lets taller drivers pull the wheel closer without sliding the seat forward.

Within the ND2 run, the 2022 model year added Kinematic Posture Control (KPC). KPC is a software feature, not new hardware: it lightly applies the inside-rear brake during hard cornering, using the rear suspension geometry to pull that corner down and reduce body roll. It works through the existing brakes and stability-control hardware. So a 2022 or 2023 ND2 has KPC; a 2019-2021 ND2 does not. 2022 is also when the US dropped the 1.5-liter discussion entirely and standardized the lineup around the 2.0.

For most buyers the ND2 is the sweet spot: the better engine, the telescoping column, and (on 2022-2023 cars) KPC, all on a body that still has the simpler (if dated) infotainment that our work targets.

ND3: 2024+

The 2024 update is the cabin-and-chassis-electronics pass, not an engine one. The 2.0-liter carries over at 181 hp.

What changed:

Infotainment. The old screen finally gives way to a new 8.8-inch display with thinner bezels and a less laggy interface. Apple CarPlay and Android Auto are now wireless, and the screen is touch-sensitive when running them. This is the line that matters for software work: the ND3 is a new infotainment generation, not the Gen 6 Mazda Connect unit found in the ND1/ND2 (and most other supported Mazdas). See supported vehicles for where the line falls — ScreenTune targets the older CMU, so an ND3 is a different platform.
Asymmetric LSD. Manual cars get a newly developed asymmetric limited-slip differential with different locking rates on- and off-throttle. The intent is more stability under braking and on corner entry and less understeer on exit.
Steering. Mazda retuned the electric power steering to reduce friction for cleaner feedback.
DSC-Track mode. Manual cars gain a less-intrusive stability-control mode for track use, separate from full-off.
Styling and lighting. New LED headlight/taillight signatures and minor exterior trim revisions.

The ND3 keeps KPC and the telescoping column. If a modern phone interface is a priority, it is the obvious pick. If you mod and tune the factory screen, it is the one phase this site can’t help you with — the infotainment hardware is different.

Which to buy

Cheapest clean ND, daily use, you short-shift anyway: an ND1 is fine and is the value play. Budget for living with the non-telescoping column if you’re tall.
Best all-around, track or autocross intent, factory screen you can tune: an ND2, ideally a 2022-2023 for KPC. This is the pick for most enthusiasts.
You want the modern infotainment and the asymmetric LSD, and don’t care about touching the factory screen: the ND3.

A few cross-cutting notes that apply to all three: every US ND uses the 2.0-liter Skyactiv-G; the RF (retractable fastback) and soft-top share the drivetrain across all years; and trim/option packages (Brembo/BBS, Recaro) matter more for resale and track use than the ND1/2/3 split for some buyers.
