The MG 5 needs 18‑19 kWh/100 km in the Warm and Cold lab tests. In the Highway cycle, it uses significantly more – 27 kWh/100 km – mainly due to increasing aerodynamic drag. With the available battery capacity, this corresponds to a range of 228 km. The On-Road Drive was performed at around 17°C and the MG 5 used 19 kWh/100 km, leading to a range of around 323 km. The consumption demonstrated in the -7°C Cold Ambient Test is high – 33 kWh/100 km – a consequence of the significantly increased electricity demand to quickly heat up the cabin to a comfortable temperature in such cold conditions.

Comments

This Index is based on a Well-to-Wheel+ approach, meaning that the Greenhouse Gas emissions related to the supply of the energy are added to those of the tailpipe. As the MG 5 is purely electric, its GHG emissions originate only from the processes of electricity supply – from ca. 51 g CO2‑eq./km for the amount of electricity needed in the Warm Laboratory Test up to 94 g CO2‑eq./km in the Cold Ambient Test. Thanks to its efficient electric powertrain and the relatively low CO2 emissions of the EU electricity mix, the car scores a high 9.5 out of 10.

Our verdict

The historic English brand MG has hit the road towards full powertrain electrification with its owner SAIC – Shanghai Automotive Industry Corporation. Tested here is the MG 5 – a station wagon with a maximum power of 115 kW and a declared installed battery capacity of 61 kWh. The mass of the empty car is relatively low at 1,560 kg. The measured test consumption values are in the expected range for this type of vehicle – around 18‑19 kW/100 km in the standard laboratory tests and 27 kWh/100 km in the Highway Test. Worth noting is the significantly increased energy demand in the Cold Ambient Test at -7°C. The number of 33.1 kWh/100 km highlights the importance of an efficient heating concept for EVs, but it shouldn't be overlooked that the MG 5's cabin was quickly heated up to provide the requested level of 23°C. With 56.5 kWh, the measured usable battery capacity matches closely the declared figure of 57.4 kWh. During the battery capacity test, the vehicle was charged with 11 kW charging power and the determined grid-to-battery-output efficiency impressed with 92% – a value which helps to reduce the overall consumption of the car and save costs to the consumer. Overall, the MG 5 finishes with an Average Score of 95% and 5 Green Stars and stands its ground among other Chinese electric vehicles tested by Green NCAP.
