Toyota Prius Steering Wheel Size (2001-2027)

Note 1: Retain actual2016Comfort AMS370 mm/8 across verifiedXW50 liftback2016–22. Test build interval02/2016–09/2019 is source application, not fullgenerationboundary. Attributable2017 ownercircular comparison is shape context rather than a secondnumeric measurement. NHP10 PriusC381 source is separate and its wrong liftback link is retired.

Note 2: Prius AWD-e is already accepted at 370 mm, 14 5/8"/8 in the XW50 liftback generation. Its completed exact application resolves old intake/generation wording. The separate NHP10 Prius C shape evidence does not transfer to this body. No applicable positive nonround restriction is established for this retained application. Unknown shape remains unknown, not certified round.

Note 3: Assessment234 establishes 2020 Prius AWD-e within the XW50 liftback generation at 370 mm, 14 5/8"/8. The separate NHP10 Prius C is not this recipient. Its older overlapping-generation note has already been resolved by the accepted exact AWD-e scope; no repeat generation research is needed. No applicable positive nonround restriction is established in this retained target scope. Unknown shape remains unknown, not certified round.

Note 4: Assessment188 establishes 2019 PriusAWD-e within the XW50 liftback generation. Preserve370 mm/8 and the completed exclusion of NHP10 PriusC381 mm. Older ambiguous-generation prose is superseded by the explicit same-year blank-trim/C-trim separation. No applicable positive flat/mixed restriction is established in the reviewed scope. Unknown geometry remains unknown, not certified round.

Note 5: 2019 Prius C NHP10 retains its completed 381 mm, 15"/8 source and the same owner flat-bottom concern already resolved for 2017/2018 Prius C. Reuse the supported same-body generation exclusion, preserving owner-grade/year limits; do not confuse it with the XW50 liftback. The retained Prius c owner thread records flat-bottom shape and slipping circular covers in the NHP10 body cohort. This is inherited same-generation evidence, not a direct observation of every 2019 grade.

Note 6: Retain actual2016Comfort AMS370 mm/8 across verifiedXW50 liftback2016–22. Test build interval02/2016–09/2019 is source application, not fullgenerationboundary. Attributable2017 ownercircular comparison is shape context rather than a secondnumeric measurement. NHP10 PriusC381 source is separate and its wrong liftback link is retired.

Note 7: Assessment138 retains the exact 2018 Prius C NHP10 application at 381 mm, 15"/8 and the same Prius c owner flat-bottom evidence. Apply the existing NHP10 shape exclusion with its inherited scope, without claiming a direct 2018 grade observation or repeating the measurement. The retained Prius c owner thread records a flat bottom and slipping circular covers in the same NHP10 body cohort. Apply the existing same-generation application rule; this is inherited shape evidence, not a direct observation of every 2017 grade.

Note 8: Retain actual2016Comfort AMS370 mm/8 across verifiedXW50 liftback2016–22. Test build interval02/2016–09/2019 is source application, not fullgenerationboundary. Attributable2017 ownercircular comparison is shape context rather than a secondnumeric measurement. NHP10 PriusC381 source is separate and its wrong liftback link is retired. Scoped accepted shape context: Attributable firsthand owner comparison: liquidtenmillion, Easley, SC, PriusChat post May17,2017, states "It is slightly bigger and it is a perfect circle as apposed to an oval. I recently switched from a 2015 to a 2017." Source=https://priuschat.com/threads/gen4-steering-wheel-size-bigger-or-smaller-than-gen3.179353/. The quoted current wheel is MY2017 Toyota Prius XW50 liftback; trim and wheel configuration are unspecified (profile Vehicle=Other Non-Hybrid; Model=N/A). The comparison preserves only this attributed MY2017 circular shape context, without establishing every option or model year and without a numeric measurement.

Note 9: 381 mm, 15" retained NHP10-generation measurement. Owner evidence reports a flat bottom and circular-cover slippage; excluded from round-cover ACES. Shape is inherited within the NHP10 cohort, not directly observed for every 2017 grade.

Note 10: Preserve REAL OEM-equivalent greatest outside axisB375 mm/8 and every actualA/B material branch; source measuredMY remains unknown. Original2010 stockBase oval road-test authority and positively established sameXW30 physical body/original wheel phase supportOther, including actual PriusPlug-InPHV scope. No orientation, circular diameter, average or invented target measurement.

Note 13: Inherited existing same-body generation application; original evidence and score preserved. Geometry remains flat_bottom.
