| Years | 2006-2015 (US model years) |
|---|---|
| Trims | 2006: Club Spec, MX-5, Touring, Sport, Grand Touring, plus the 750-car 3rd Generation Limited. 2009: SV, Sport, Touring, Grand Touring. NC3 (2013-15): Sport, Club, Grand Touring (per a buying guide; the 2013-15 Mazda sheets were not read). Power Retractable Hardtop (PRHT) from the 2007 model year. |
| Engine | 2.0L MZR LF-VE inline-four in every US NC: 170 hp at launch, listed as 167 hp (MT) / 158 hp (AT) on the 2009 sheet after a rating change; 140 lb-ft. 5-speed or Aisin 6-speed manual, or 6-speed automatic. The 2009 manual got forged internals, an oil cooler and a 7,200 rpm redline; automatics kept the earlier internals. |
| Notes | Sub-generations: NC1 2006-08, NC2 2009-12 (facelift), NC3 2013-15. First Miata on 5x114.3 wheels (NA/NB and the later ND use 4x100). Limited-slip differential on manual cars only (2009 sheet). The PRHT adds roughly 80-90 lb and leaves no room for a roll bar. The coolant expansion tank is pressurised plastic and is the best-known failure point. |

| Note | Mazda sheets for 2006 and 2009 were read; 2007-08 and 2010-15 trim-to-wheel mapping not checked. Factory offset is unclear: a vendor gives 55 mm for the 17-inch wheel, while the Miata.net wheel table lists 45 mm for NC wheels (16 or 17 inch); the Mazda sheets and manuals read print none. Tire pressure 200 kPa (29 psi) front and rear on both sizes. |
