Why range isn't everything

Charging speed, efficiency, and honesty matter more than the biggest number.

A 620 km car that charges slowly loses to a 480 km car that charges fast on any trip over six hours. Time at the charger is the real metric, not kilometers on the spec sheet.

Efficiency is the quiet multiplier. At 15 kWh per 100 km, an 82 kWh pack goes further than a careless 100 kWh pack. Weight, aero, heat pump — the unglamorous list.

Then honesty: a range figure you can actually repeat beats a heroic one you see once. Our estimator shows city, mixed, and highway separately, because one number is a lie told politely.
