WLTP consumption for the entry-level trim, in kWh per 100 km. Lower is better here, unlike every other ranking on the site. Efficiency is what turns a battery into range: two cars with the same pack differ by their consumption alone.
65 of 84 models sold in USA have a published WLTP consumption figure. The others are missing that figure rather than absent from the market.
