Passenger space and everyday maneuverability, scored within its class.
Combines how comfortably this vehicle fits passengers and cargo with how easily it maneuvers in real-world conditions — normalized within its Compact SUV segment for fair comparison. Methodology →
Safety
Scored on standard crash-avoidance technology alone — no published crash tests yet.
No published NHTSA or IIHS crash-test results yet.
What do NHTSA & IIHS ratings mean? →Combines crash-test protection — NHTSA frontal, side, and rollover ratings plus the IIHS crashworthiness sub-tests (small- and moderate-overlap front, side, headlights) — with standard crash-avoidance technology. New model years without published crash tests are scored on crash-avoidance features alone and capped until tested. Methodology →
