Maruti Suzuki models have been the most fuel efficient cars in India since several decades. However, the recent testimonials from the Automobile Research Association of India reveal Tata Nano to be a more fuel efficient car. ARAI testified that Nano consumes much less fuel than the most economical models of other auto makers.
ARAI in Pune testified that Nano is the most fuel efficient car in India amongst all commercially launched 450 small car models in India. It gives nearly 23.6 kmpl of fuel efficiency under standard conditions.
Maruti Suzuki currently owns nearly 55 percent of the total market share in India and accounts for nearly two-third of the small car sales in India. Its model A-star is known to have clocked fuel efficiency of 19.3 kmpl. Its highest selling model Alto also delivers mileage equal to Hyundai i10 that delivers a fuel efficiency of 18.1 kmpl.
