Kia e-Niro review - MPG, CO2 and Running Costs

Few moving parts and an efficient electric powertrain make for very low running costs

Like any EV, the Kia e-Niro should cost very little to run when compared with conventionally powered rivals. It should only cost around £8 to fully charge the e-Niro from a domestic power supply (based on an average unit price of 12.5p per kWh of electricity on an off-peak tariff), which undercuts every combustion-engined rival available by a considerable margin.

Similarly, the Kia e-Niro’s lack of traditional engine, gearbox and other associated moving parts should mean that costs of spares and repairs will be far lower than in a conventional car. Kia’s excellent warranty applies as normal to the e-Niro too, so you’ll have peace of mind during ownership.   

Electric range, battery life and charge time

The 64kWh battery mounted under the e-Niro’s floor provides a claimed WLTP-measured range of 282 miles – a figure that should be achievable if you drive with a light touch. During our test, we calculated that a more accurate range in mixed driving is around 250 miles – still more than enough to fend off even the worst case of range anxiety.

It should take around nine hours and 50 minutes to fully charge the e-Niro via a wallbox installed at home, while a 50kW fast charger will get the car to 80 per cent capacity in around one hour and fifteen minutes; find a 100kW charger and that time will drop to around 54 minutes.

The e-Niro comes as standard with a Type 2 cable for public chargers and a three-pin plug for connecting to a mains supply. Charging via a domestic supply will take a long time, though – somewhere around 29 hours for a full charge. 

Insurance groups

The Kia e-Niro sits in insurance group 28, just above its Hyundai Kona Electric relative in groups 22 to 27 (depending on trim and battery size). The BMW i3 occupies a similar range of groups 21 to 29 depending on specification, with the S model being the most expensive to insure. 


Thanks to the constant and rapid evolution of EV technology, electric cars like the Kia e-Niro are particularly at risk of bad residual values. However, the e-Niro shouldn’t fare too badly after 36,000 miles and three years come trade-in time. Our experts predict that the e-Niro should hold on to a shade over 40 per cent of its value – not too far behind its various hybrid Niro siblings which manage 42.8 to 49.3 per cent. The pricier BMW i3, by contrast, should retain around 37.8 to 41.7 per cent of its value after the same period. 

It’s worth noting that customer demand for the e-Niro is high – waiting lists are long, so used values should remain high in the nearer future.
