Our verdict

Hyundai’s all-electric small family car, the Ioniq, uses a 88 kW motor as its propulsion unit. Local pollutant emissions are zero, of course, as no fuel is burned during the tests, and the Ioniq scores a maximum 10 in the Clean Air Index. Likewise, emissions of carbon dioxide, an important greenhouse gas, are zero and Energy Efficiency is very good, with consumption not exceeding 20 kWh / 100 km in any of the tests, although the high-load highway test makes noticeably greater demands than the others. The Ioniq demonstrates that full electric propulsion is the greenest means of transportation currently available.
