In 2025, diesel cars still play an important role in India, especially for those who drive long distances regularly. With rising fuel costs and long highway stretches, diesel engines offer better fuel efficiency and torque than their petrol counterparts. While the market is slowly shifting toward electric and hybrid vehicles, diesel cars remain the top choice for highway commuters, taxi operators, and inter-city drivers who want powerful yet fuel-efficient vehicles.
