Nexon EV long range

Good interior and excellent in handling.. but very poor in mileage .. after committing for 450 km from tata I am getting only 260 km in economy mode . It’s like cheating by Tata motors .. if your can’t able to provide promised range don’t commit.. I feel now it’s like tata Indica ..if you can’t assure 350 km range have to give compensation for customers.
