Miata: All the Gens, and What Makes Them Different

Mike introduces the video, explaining he will cover Miata generations, sub-generations and acronyms like NA/NB/NC/ND at a top level using a lineup of shop, employee and friend cars.

Presents the modified NA6 as the original Miata/MX5 released in 1989 that started the lineage.

Explains that the fourth and fifth VIN digits (e.g. NA) identify the Miata generation, showing the VIN plate on the driver's side.

Describes why the first three years are called NA6 (1.6L four-cylinder) and how the car revived the British-roadster formula with Japanese reliability.

Covers the 1994 NA8 update with the 1.8L engine, upgraded axles, differential and subframe bracing, and the 1990-1997 NA production run.

Introduces the NB1 with integrated headlights, similar chassis, improved 1.8L head and intake, and updated ECU electronics.

Compares wheel horsepower of NA6 (~90), NA8 (~100) and NB1 (~110) and notes the NB1's added chassis bracing and suspension tweaks, with a passing comparison to MGB/Spitfire driving feel.

Covers the 2001-2005 NB2/NBFL with updated emissions electronics, VVT 1.8L engine, new six-speed option, and broad 1990-2005 parts interchangeability.

Describes the 2004-2005 MSM with factory turbocharger, unique bumpers and trim, mixed NB1/NB2 engine parts, factory fire ending production, and ~135-140 whp.

Explains the 2006-2008 NC1's all-new stiffer chassis, Ford-shared 2L Duratec/MZR engine, new transmissions, and multi-link rear suspension.

Covers the 2009 NC2 aesthetic refresh, forged-internal 2L engines in manual cars, and ~130-135 whp output.

Explains the PRHT introduced in 2007 as a motorized folding roof option and its weight penalty versus soft tops.

Describes the 2013 NC3 bumper differences, project Megalodon NC2 wearing an NC3 bumper, and the PRHT NC being the heaviest Miata by roughly 100-150 lb.

Covers the 2016-2018 ND1's all-new chassis, direct-injection Skyactiv 2L, six-speed only manual, revised suspension, ~150 whp, gram strategy weight savings and electric power steering.

Describes the 2019 ND2 with reworked head, intake, exhaust and throttle body raising output to ~167 whp and a higher redline, plus the 1.5L backstory.

Notes the 2017 introduction of the retractable fastback power roof as the ND equivalent of the PRHT.

Covers the 2024 ND3 with full LED lighting, wider infotainment screen, luxury-leaning upgrades and kinematic posture control brake-based chassis stabilization.

Speculates on a possible next-generation Miata based on ~10-year cycles, asks viewers for input, and closes with contact info and subscribe call.
