Our verdict

BMW has used weight-saving carbon-fibre technology to keep the i3 at a trim 1270 kg, although its 125 kW electric motor and battery pack limits the weight-loss that can be achieved. Electric motors deliver a high torque and the i3 delivers a hefty 250 Nm. Local pollutant emissions are zero, of course, as no fuel is burned during the tests, and the i3 scores a maximum 10 in the Clean Air Index. Energy Efficiency is also very good, with consumption not exceeding 20 kWh/100 km in any of the tests. In an additional test, performed for information only, consumption was as low as 10.2 kWh/100 km with the car in “ECO PRO +” mode, in which its maximum speed is limited to 90 km/h. Of course, emissions of carbon dioxide are zero. Overall, the i3 demonstrates that full electric propulsion currently offers the greenest mode of transport around.
