Tata revises range for its EV portfolio after new MIDC test cycles
Tata Motors has released revised range numbers for its complete EV portfolio in response to the government's (MoRTH) addition of new parameters to the MIDC test cycles. Previously, these data were only based on a city (Urban) driving cycle, but the ministry now requires all carmakers to test and disclose range values that encompass both urban and extra-urban cycles.
The MIDC range now includes a highway run, which increases the average testing speed from 19kmph to 31kmph and the maximum speed from 50kmph to 90kmph, resulting in a lower EV range claim. It should be noted that EV ranges are often lower on highway cycling than in city driving.
The table below compares the existing and updated MIDC ranges, as well as Tata Motor's own range test cycle. The brand calls it C75, which is believed to represent a near-real-world driving range, with 75% of owners expected to reach it.
Apart from testing at higher average speeds of 40kmph and a top speed of 120kmph Tata claims that, unlike the MIDC cycle, it has AC running, higher loads (up to 250kg, compared to the MIDC's 150kg), and greater temperature variance (10-40°C vs. 20-30°C on the MIDC cycle).
