Tata Motors has announced revised range figures for its entire EV portfolio after the government (MoRTH) added more parameters to the MIDC test cycles. Earlier, these figures were solely based on a city (Urban) driving cycle, but the ministry has now mandated all carmakers to test and declare range values that include Urban and extra urban cycles.

1. Curvv EV 55 MIDC range down from 585km to 502km
2. Nexon EV 40.5 range down from 465km to 390km
3. New MIDC range figure still higher than Tata’s C75 range test

With the MIDC range now incorporating a highway run – where average testing speed has increased from 19kph to 31kph and maximum speed from 50kph to 90kph – EV range figures have decreased. It should be noted that EV ranges are generally lower on highway cycles compared to city driving.

The table above shows the previous and revised MIDC ranges, along with Tata Motor’s own range test cycle. The brand calls it C75, which is said to be a near-real-world driving range, and 75 percent of owners can expect to achieve this. 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, higher loads (up to 250kg, compared to the MIDC’s 150kg), and a greater temperature variance (10-40-deg C compared to 20-30-deg C on the MIDC cycle).

More carmakers are likely to reveal revised MIDC range figures for their models in the coming days. Stay tuned.
