The shift to new BS-VI emission norms has been one of the toughest challenges for the Indian automotive industry. Only three years after the implementation of the BS-IV, manufacturers had to develop engines that were compliant to the new norms. This coupled with the already ailing industry posed a big problem for manufacturers.
Companies like Maruti Suzuki and Renault have completely ditched their diesel engines for the new norms. The new engines are aimed at being more fuel-efficient and pollute less, leading to a difficult future for diesel powertrains in the market.
With the BS-VI influx, there is a major change in fuel efficiency of most cars, hence here are the top 5 most fuel-efficient BS-VI cars in India.
