Tata Motors has announced revised range figures for its range of EVs. The new range figures come in the wake of the Ministry of Road Transport and Highways implementing new regulations for MIDC range testing. The claimed MIDC range of EVs previously only comprised of figures for intra-city driving but will now be calculated on the basis of range in the city and on the highway. The new MIDC figures will become applicable for all Tata EVs from September 10, 2024.

MIDC Testing Parameters
Tata also revealed the testing standard for MIDC range calculations. As per the company, MIDC range is calculated using some fixed parameters including speed, vehicle loading and air conditioning. MIDC range testing is conducted with the air-con switched off and with a vehicle carrying a load of 150 kg. The city cycle sees the vehicle speed capped at 50 kmph while on the highway the speed is capped at 90 kmph. The test is also conducted in ambient temperatures of between 20 and 30 degrees Celsius.

For its C75 figures, Tata says that the max speed is upped to 120 kmph on the highway while the ambient temperatures range from as low as 10 degrees Celsius up to 40 degrees. Additionally, the vehicle load is also increased to up to 250 kg and the car’s multiple regeneration modes are also factored in.
Tata however says that its claimed real-world range figures are not applicable for all use cases.
