Tata Curvv EV, Punch EV, Nexon EV Range Reduced - New MIDC Test Cycle

Tata Motors has released the revised range figures of its electric vehicle portfolio. This comes after the Ministry of Road Transport and Highways (MoRTH) has added more parameters to the MIDC test cycles. Tata Motors currently has the largest number of electric vehicles including the Tiago EV, Tigor EV, Punch EV, Nexon EV and the Curvv EV. 

Earlier, the range figures released by automakers were based on City/Urban driving cycle. Now, the Ministry has issued a notification to all carmakers to test and declare the range figures that include Urban and extra Urban cycles. 

The MIDC range now includes a highway run. In the latest update, the average testing speed has increased to 31kph from 19kph, while the maximum speed has increased from 50kph to 90kph. These two big updates resulted in the decrease of EV range figures. EVs are designed to offer maximum range in the City; however, the range decreased significantly on highways at high speed. 

Tata Motors has also released its own range test cycle, called C75, which is claimed to be a near-real-world driving range. Tata claims that 75 percent of its owners can expect to achieve the given range. Adding to it, Tata Motors said that its EVs are tested at higher average speeds of 40kmph and a top speed of 120kmph. 

Adding to it, unlike the MIDC cycle, the vehicles tested have AC running, higher loads and greater temperature variance compared to the MIDC cycle. In the MIDC cycle, the EV has the AC running, loads of 150kg and a temperature variance of 20-30 degree Celsius. 

The Tata Curvv EV 55kWh version is now claimed to offer a MIDC certified range of 502km, which was 585km in the older MIDC cycle. In the brand's own C75 range test, it offers a range of around 400-425km on a single charge. Similarly, the Curvv EV 45kWh version delivers 430km compared to 502km. Moreover, the brand's own range test gives Curvv EV 45kWh a range of 330-350km. 

Similarly, the Nexon EV 40.5kWh and 30kWh versions now offer a range of 390km and 275km, respectively, (new MIDC cycle). The Punch EV 35kWh range drops to 365km from 421km, while the 25kWh version now offers a certified range of 265km as compared to 315km in the previous MIDC cycle. The Tiago EV range drops to 275km.
