I am confused between buying the Tata Harrier Pure X Dark Edition Diesel AT and the Tata Harrier EV Fearless+ 75 kWh. I have charging facilities available both at my apartment and at my office, and I live in Hyderabad. Since I plan to keep the car for the next 10 to 12 years, would it be better to buy the Tata Harrier Pure X Dark Edition Diesel AT, which is based on an older platform, or should I go with the Tata Harrier EV Fearless+ 75 kWh, which is built on a new platform and features an all-new architecture? Alternatively, would it be wiser to wait for Tata to launch the next-generation Harrier ICE? By then, there may also be more clarity on the future of iso-butanol as an automotive fuel.
Go for the Tata Harrier EV Fearless+ 75 kWh. With charging available at both home and the office, the ownership experience is well suited to an EV. The Harrier EV also offers a long driving range, a spacious cabin, and a premium feel.
The Tata Harrier Pure X Dark Edition Diesel AT remains a capable SUV, and its Land Rover-derived platform is not an issue. However, considering the relatively low running requirements and the long-term savings on fuel and maintenance, the electric car makes more sense in this case.
That said, since the plan is to keep the vehicle for 10 to 12 years, it is worth considering that the battery will gradually lose capacity over time. This can reduce both driving range and performance. In addition, the resale value of diesel SUVs is likely to remain stronger than that of EVs over such a long ownership period.
As for iso-butanol, there is currently no official policy or implementation timeline as there was for the E20 petrol. Modern diesel engines are engineered with a degree of tolerance for future fuel changes, and if iso-butanol-blended diesel is introduced, manufacturers are expected to develop engines that are compatible with it. At present, however, there is no reason to delay the purchase solely because of uncertainty around iso-butanol.
