Tata Motors: Revised EV Range To Set Expectations

Tata Motors has announced major overhauls of the range certifications of its entire EV line-up, effective September 10, 2024. The revision comes after the Ministry of Road Transport and Highways (MoRTH) reworked the testing cycle to include a full urban and extra-urban driving condition.

Testing Parameters Revised

So far, EVs were tested only for P1 urban conditions under MIDC. Under the new regime, manufacturers will also have to take into account P2 extra urban conditions, thus factoring in driving on the highway. This has changed the average testing speeds from 19 km/h to 31 km/h and maximum speeds from 50 km/h to 90 km/h, and range estimates have consequently come down for many models.

Tata Motors Steps Forward

Besides the MIDC range, Tata Motors has also developed another range figure, which they call the “C75” range. This is supposed to give a more realistic estimate of what 75% of customers can achieve from historical data from over 165,000 Tata EVs, which have cumulatively covered 4 billion kilometers on roads. This effort of Tata’s attempt at improving transparency and customer understanding about how EVs will perform in the real world.

Revised Range of Tata Motors EV

After the revised guidelines by MoRTH, Tata Motors updated the range certificates of its electric vehicle portfolio. 

Revised Tata Curvv EV: 

• The range of the 55kWh version is reduced from its original 585 km to 502 km. It gets a new C75 range- 400-425 km. 
• Also, the range for the 45 kWh version has been reduced from 502 km to 430 km, while the C75 range goes up to 350 km.

The Tata Nexon EV

• Range has dropped from 465 km to 390 km for the 40.5 kWh variant, with the C75 range of 290-310 km,
• From 325 km to 275 km in the case of the 30 kWh variant. Providing 210-230 km range for C75.

Tata Punch EV

• The range has been revised to 365 km for the 35 kWh variant from the earlier 421 km and C75 range of 270-290 km. 
• That of the 25 kWh variant has come down from 315 km to 265 km. Will deliver C75 range of 190-210 km.

The Tata Tiago EV

• 24 kWh variant had its range reduced to 275 km down from 315 km, Giving C75 range of 190-210 km. 
• The range on the 19.2 kWh variant fell to 221 km from 250 km. Will Deliver 150-160km range for C75.

These changes are reflections and testimony to the commitment of Tata Motors regarding transparency and customer awareness on the performance of EVs.

Impact on Other EV Manufacturers

This move by Tata Motors will probably act as a benchmark for other automobile companies, too, in order to get their range certifications updated according to new MIDC guidelines. Precise range reporting is going to become increasingly important for consumer trust and, therefore, market expansion of the electric vehicle segment.
