The utility vehicle segment has been witnessing dropping sales recently as we conclude from the sales reports. As most UVs are preferred with a diesel engine, the axe from eco-warriors is looming large over them, taking valuable customers away from them. While the Innova Crysta has had a petrol engine for a couple of years, the XUV500 just recently received one. The Tata Hexa doesn’t even feature it as an option. But petrol engines are rarely chosen by those buying a seven seater MUV.
