What real-world EV range to expect in India, not the claimed figure

The Maruti e Vitara: 440 km claimed, under 390 km in real use

Maruti sells the e Vitara's smaller battery on an ARAI, or MIDC, claimed range of 440 km. For the global market the same 49kWh pack is rated at 344 km on the stricter WLTP cycle, a figure Maruti also publishes. Neither number is what an owner actually sees on Indian roads.

A Team BHP member ran a real world test on the 49kWh car: 139.24 km covered using 36 percent of the battery, in mixed traffic with elevation changes, both Eco and Normal modes, the air conditioning on through the drive, and no attempt at hypermiling. Projected to a full charge, that works out to 387 km, roughly 12 percent short of the 440 km MIDC figure, though comfortably ahead of the 344 km WLTP number.

That gap matters because the 440 km figure is the one printed in Maruti's brochure and used in showroom conversations. A buyer who plans a 350 km round trip assuming the claimed range has far less margin than the number suggests, even before accounting for highway speeds, which Autocar India's own short drive found pull efficiency down to about 4.8 km per kWh against roughly 7 km per kWh in the city.

The Tata Harrier.ev: 622 km claimed, 401 km on test, 375 to 400 km for one owner

Tata's Harrier.ev tells the same story at a bigger scale. The 75kWh all wheel drive version carries an MIDC claimed range of 622 km. Tata itself does not stop there. In its own launch press release, the company quotes a "C75" estimated real world range of 480 to 505 km for the 75kWh pack, an internal test cycle meant to be more representative of actual driving than the MIDC number used for the brochure.

Autocar India then drove the AWD Harrier.ev in Eco mode across city and highway routes in Navi Mumbai, air conditioning fixed at 22 degrees C, and recorded 401 km on a full charge, which the outlet called an impressive result for a 2,335 kg SUV but still well short of the 622 km claim.

A Team BHP owner's five month log on the same Empowered variant lines up with that test: 375 to 400 km in daily use, with the owner adding that smoother inputs and better use of regenerative braking could likely push it closer to 450 km. None of these three numbers, the 622 km claim, Tata's own 480 to 505 km estimate, or the 401 km test, agree with each other, and the owner's real figure sits below all three.

What this means for a buyer

Three different numbers exist for the same car before you even add Indian conditions: monsoon traffic, AC load, and Bengaluru's stop start commute, which the Navi Mumbai test above already partly captures. The practical rule from this data: when a company publishes its own "real world" or C75 figure alongside the MIDC number, use that lower figure for your planning, and when it does not, assume a cut of 10 to 20 percent from the MIDC claim for in town driving and more on the highway.

If your daily driving, including a return trip or two, regularly needs more than 70 percent of the MIDC claimed range, buy the larger battery variant rather than the one that just clears your number on paper. The price difference between battery sizes is smaller than the cost of range anxiety on a 300 km weekend drive out of Bengaluru.
