New MIDC range figure still higher than Tata’s C75 range test.

Tata Motors has announced revised range figures for its entire EV portfolio as the Indian Government (MoRTH) has added more parameters to the MIDC test cycles. Earlier, MIDC range figures were only based on a city (Urban) driving cycle, but the Ministry has mandated all carmakers to test and declare range values that include Urban and Extra urban cycles.
Considering the MIDC range now includes a highway run – the average testing speed has risen from 19kph to 31kph, while the max speed has increased from 50kph to 90kph – the distance that EVs are rated at has come down. It should be noted that EV range is typically lower on a highway cycle, compared to a city run.
The table above shows the previous and revised MIDC ranges, along with Tata Motor’s own range test cycle that the brand calls C75, which is said to be a near-real-world driving range that 75 percent of owners can expect to achieve. In addition to tests conducted at higher average speeds of 40kph, and a top speed of 120kph, Tata says that unlike the MIDC cycle, it also has the AC running, has higher loads (up to 250kg, compared to the MIDC’s 150kg), and has a greater temperature variance (10-40-deg C compared to 20-30-deg C on the MIDC cycle).
However, even Tata’s C75 range test figures do not match Autocar India’s tests. For reference, on our preliminary highway tests, the longer range Curvv EV 55 delivered 359km on a single charge, which is still significantly lower than Tata’s claimed 400-425km.
More carmakers are likely to reveal revised MIDC range figures for their models in the coming days.
