The list of India’s most fuel-efficient diesel cars has drastically changed in recent times. Ever since the BS6 era kicked-in April this year, well-known engines from Fiat’s Multijet, Renault-Nissan’s K9K units have been stopped. However, car manufacturers like Tata Motors, Hyundai and Ford continue to roll out small diesel engines which have been tweaked to meet BS6 norms. Hence these carmakers have some of the most economical cars on sale at the moment.
Here are the top five most fuel-efficient BS6 diesel cars on sale in India:
1. Hyundai Aura
Hyundai’s Aura comes powered with a 1.2-litre diesel engine which does the duty in the compact sedan. The South Korean carmaker’s Aura’s diesel-AMT has an ARAI-certified fuel economy of 25.40 kmpl, while the manual variant impresses with a 25.53 kmpl.
