The MG4 Comfort sold in Nepal lists 350 km under WLTP. The Tata Punch EV long-range version lists 365 km under MIDC. Those two numbers look close, but they come from different tests. You cannot use the 15 km difference to decide which car will go farther on a Nepal road.
WLTP is an international laboratory test set out in UN vehicle regulations. ARAI figures come from Indian testing; ARAI publishes the vehicle range measurement standard. Both can help you compare cars tested the same way. A laboratory figure cannot tell you the distance you will get on a climb outside Kathmandu.
Tata also gives 270–290 km for the Punch EV long-range version from its own Nepal-market testing. This is a manufacturer estimate. Ask local owners how the car performs on the route you care about before using any figure to plan a trip.
Ask which figure belongs to the car
Have the dealer write the test name and range number for the exact variant you plan to buy. Check the battery size too. The same model name may cover versions with different batteries.
Do not subtract a WLTP figure from an ARAI figure and call the difference extra range. If the two cars use different tests, ask for figures measured by the same method. Our EV price list labels the range method where the source provides it.
An imported review may quote a range measured for another market. Check that the review covers the same battery and motor sold in Nepal before using its number to plan a trip.
Work out what your route needs
Kathmandu traffic, a climb toward Nagarkot and a faster highway run will use battery at different rates. Air conditioning, luggage and rain can change the result. Some energy may return through regenerative braking on a descent, but do not assume it will replace everything used on the climb.
If you already drive an EV, watch how much battery a familiar journey uses. For a new car, ask for a test drive on a route like yours and speak to owners who make that trip. Before a long drive, find charging stops you can actually use and leave room for a detour or delay.
The brochure number is useful once you know which test produced it. For the drive home, plan with the road and charger information you have today.
