According to the Worldwide Harmonised Light Vehicles Test Procedure (in the EU), it has a range of 289km, but Hyundai India is claiming 452km (certified by the Automotive Research Association of India). The ARAI has tested it on the MIDC (Modified Indian Driving Cycle) mode, or ‘ideal’ conditions. While we haven’t driven it on public roads, it should easily be able to cover more than 300km on a full charge (the EU test is based on rigorous real-driving data).
