Reva G-Wiz.From the Daily Telegraph.
Its range is 40 miles from a battery capacity of 9.6kWh. Charging efficiency will be about 70 per cent, so a full charge will take about 14kWh (units) of electricity, and average UK CO2 output from gas, coal, nuclear and renewables is about 0.5kg/kWh. Thus the G-Wiz is responsible for 7.3kg of CO2 every 40 miles (64km), or 114g/km.
The petrol Smart emits 113g/km and the VW Polo 1.4 diesel 119g/km, so we may assume a practical electric car will emit at least as much CO2 as its diesel equivalent.
