Snapshot – World over, cars are getting more fuel efficient each passing year as manufacturers seek to maximize each drop of the liquid fossil remains. This year’s top ten list of India’s most fuel efficient cars has a surprise in store. There’s not even a single Maruti Suzuki car in the list of India’s ten most fuel efficient cars and the latest automaker to embrace diesel power, Honda, tops proceedings. Diesel engines are inherently more fuel efficient than petrol powered ones and this fact comes out in this list, with only one petrol powered car, the Tata Nano, featuring in the top ten.
Honda City Diesel – 26 Kmpl
A sales success right from word go, the 2014 Honda City has its 1.5 liter i-DTEC turbo diesel engine 98.6 Bhp-200 Nm) to thank for its superb performance at the hustings.

The City Diesel uses a 6 speed manual gearbox with the final ratio making for relaxed cruising and in consequence, great fuel efficiency.
Honda Amaze Diesel – 25.8 Kmpl
The Honda Amaze is India’s second most fuel efficiency car despite being lighter than the City Diesel sedan and using the same 1.5 liter i-DTEC diesel engine. The key difference is in the gearboxes used by the City and the Amaze. While the City features a 6 speeder, the Amaze makes do with a 5 speeder. This apart, there’s little to distinguish both cars in terms of engine and fuel efficiency. The Amaze Diesel manages an ARAI certified 25.8 Kmpl.
Chevrolet Beat Diesel – 25.4 Kmpl

Tata Nano Petrol – 25.4 Kmpl
The only petrol powered car in this list is the Tata Nano, which features a 623 cc-twin cylinder engine that outputs 37 Bhp and 51 Nm. Also, the Nano’s engine is the least powerful engine in this list.

Ford Fiesta Facelift Diesel – 25.01 Kmpl
The latest C-Segment car in town comes with tasty new form factor that has also resulted in a 3 % improvement in aerodynamics.

Toyota Etios Diesel – 23.6 Kmpl
