Electric motors convert 85–95% of stored energy into motion. Gas engines manage 20–40%. The gap is physics, not marketing, and it explains every EV performance claim.
kWh measures battery storage, kW measures charging speed, and efficiency is the number that decides whether a 75 kWh pack delivers 225 or 337 km.
A Renault 4 and a Model Y share the same highway physics. The intuitive size penalty for big EVs vanishes once you understand how drag really works.
The Chevy Bolt and the Equinox EV post nearly identical highway efficiency despite a 1,000-pound gap. The 'small EV equals green EV' pitch was a vibe, the EPA data never backed it up.
Canadian EV coverage keeps treating "small" as a shortcut for "efficient." At highway speed, that assumption is wrong, and it's costing buyers real money.
Four test cycles, four different efficiency answers, and a subsidy architecture that quietly rewards inefficient small EVs. The policy story behind the physics.
