The MG 4 needs 16.4‑17.6 kWh/100 km in the Warm and Cold lab Tests respectively. In the Highway cycle with full-power acceleration phases, it uses 26.2 kWh/100 km – this corresponds to a range of 268 km. In the On-Road Drive, the MG 4 used 20.8 kWh/100 km, corresponding to a range of 338 km. This consumption is impacted by the 11°C ambient temperature at which the test was performed. The electricity demand rises significantly to 34.9 kWh/100 km in the Cold Ambient Test at -7°C, where the heating system and the thermal comfort it provides have a strong impact on the energy demand.

Comments

The Greenhouse Gas (GHG) Index is based on a Well-to-Wheel+ approach, meaning that the GHG emissions related to the supply of energy are added to those of the tailpipe. Following this approach, the estimated GHG emissions of the fully electric MG 4 originate only from the upstream processes of electricity supply – ca. 46 g CO2‑eq./km in the Warm Lab Test, increasing up to 98 g CO2‑eq./km in the Cold Ambient Test. Thanks to its electric powertrain and the relatively low GHG of EU electricity production, the MG 4 scores high 9.4/10.

Our verdict

The MG 4 EV is the first 100% electric hatchback produced by the Chinese automotive manufacturer SAIC Motor under the British MG marque. Tested here is the ‘Comfort' version with a maximum power of 150 kW and a declared usable battery capacity of 61.7 kWh. With measured consumption values of around 16‑18 kW/100 km, both standard laboratory tests - with warm and cold powertrain start - score full points in the Energy Efficiency Index and Greenhouse Index. The measured test consumption values are in the expected range for this type of vehicle and 26 kWh/100 km is recorded in the Highway Test. The highest consumption is measured in the Cold Ambient Test at -7°C – with 34.9 kWh/100 km. The heating system uses significant power to provide a comfortable temperature level very quickly to the driver, using a PTC heater. During the battery capacity test, the vehicle is charged with 11 kW. Here, a real usable battery
capacity of 63.2 kWh was obtained, higher than the officially declared value. To charge the car starting from a fully depleted condition, 70.3 kWh have to be delivered by the electricity grid, which results in a good but fairly typical grid-to-battery-output efficiency of 89.9%. Overall, the MG 4 reaches an average score of 95% and easily receives 5 Green Stars.
