Check 1
These dimensions are Toyota's nominal cabin/body measurements for two cited Japanese grades; they are not seat-adjusted legroom, actual cargo capacity or door aperture clearances.
Check 2
Compare DAA-NHW20 to DAA-ZVW30 and the cited 2007 G and 2011 L catalog editions. Do not imply all trims, all Prius 30 years or overseas-market cars have exactly these measurements.
Check 3
A 15 mm catalog cabin-length difference is not a promise of more usable passenger space in every seating position.
Where the numbers came from
This original model-generation comparison uses Toyota Japan's original February 2007 NHW20 G and December 2011 ZVW30 L certified-used catalog entries. The four measurements are transcribed by exact edition and a simple numerical difference is calculated only for like-for-like nominal interior dimensions.
