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 e-Niro is available with either 39kWh or 64kWh batteries, providing claimed WLTP-measured ranges of 180 and 282 miles, respectively. These figure that should be achievable if you drive with a light touch. During our test of the 64kWh model, 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 six hours and 10 minutes to fully charge the e-Niro via a wallbox installed at home, while a 50kW fast charger will get the car to 80% capacity in around one hour; 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 18 hours for a full charge. 

Insurance groups

The e-Niro 64kWh model in 4 trim sits in insurance group 29, 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 poor residual values. However, customer demand for the e-Niro is high, so it shouldn’t fare too badly after 36,000 miles and three years come trade-in time.
