Most Efficient Cars in India

Here are the top 10 most efficient cars in India based on their highway fuel consumption (in km per litre).

Four different power sources are used. The top three are electric cars and use a calculated kilometres per litre equivalent figure. The next two vehicles built by Indian manufacturer Maruti are powered by compressed natural gas, then we have the Tata Nano with its tiny petrol engine, followed by the diesel cars.

While Indian car makers offer a good selection of efficient hatchbacks and sedans, some of the other categories of vehicle are largely occupied by the European manufacturers.

ARAI fuel efficiency tests

The Automotive Research Association of India (ARAI) is responsible for conducting car fuel efficiency tests through the use of a standard protocol called the Indian Driving Cycle (IDC).

The IDC simulates a typical Indian journey over 10 km, travelling at an average speed of 31.6 kph. There are periods of cruising in top gear at speeds of up to 90 kph and periods of stopping and starting at lower speeds.

Exhaust gases are captured, analysed and a standard empirical formula is applied to the emissions to arrive at the fuel efficiency of the vehicles.
