What is the expected warranty on the Tata Curvv EV battery?

From what I've learned talking to Tata service managers, the warranty structure will likely be: Battery pack: 8 years/160,000 km Electric motor: 5 years/100,000 km * Standard vehicle: 3 years/100,000 kmThere might be an optional extended warranty package you can purchase. The important thing to understand is that battery warranty typically has a capacity retention clause - if your battery holds less than 70% of its original capacity within the warranty period, they'll repair or replace it. This is actually quite generous since most batteries degrade much slower than that with proper care.

Tata is expected to offer an 8-year/160,000 km warranty on the Curvv EV's battery pack, which is pretty standard in the industry now. However, there might be a separate warranty on battery capacity retention - typically guaranteeing at least 70% capacity after 8 years. Some competitors are offering longer warranties, so Tata might surprise us with a more competitive package for their flagship EV. The warranty usually covers manufacturing defects and excessive capacity degradation, but not damage from accidents or improper charging.
