Tailpipe emissions

Cleaner than 35% of 2021 vehicles. NRCan rates it 4 out of 10.
Tailpipe only. It does not count the emissions of producing the fuel, or of generating electricity for an electric vehicle — the EV comparison does account for the grid.
How this is measured: Ranked against vehicles of the same model year, not against everything ever rated — comparing a 2004 SUV with 2026 hybrids would rank the calendar rather than the car. Where a model has several rated versions, the median one is used.
