• Hyundai Grand i10 Nios gets a BS6 petrol engine and BS4 diesel engine.

• Both 1.2-litre engines available with manual and AMT options.

• We tested both the petrol and diesel MT powertrains.?

• Claimed mileage figure for petrol-MT is 20.7kmpl and 26.2kmpl for diesel-MT.

• Real-world fuel efficiency tests show both falling short of their claimed mileage in city and highway driving.

The third generation of the Hyundai Grand i10 Nios was launched with prices ranging between Rs 5 lakh to Rs 7.99 lakh (ex-showroom Delhi). It is offered with a set of 1.2-litre petrol and diesel engines, both available with the choice of a 5-speed manual transmission or an AMT.? The petrol unit is BS6-compliant while the diesel variant is still in its BS4 state.

Here’s how the manual-transmission variants of both engines performed in our fuel efficiency tests:

In real-world driving conditions, both the petrol and diesel Grand i10 Nios were well short of their claimed mileage figures which are recorded under a controlled environment. The petrol unit claimed over 20kmpl but its city mileage was 5kmpl less and around 2kmpl down in highway conditions.

The diesel engine also fell short of the claimed efficiency figure of more than 26kmpl. It was able to achieve a mileage of over 19kmpl in the city but it didn’t improve much on the highways where it still did less than 22kmpl. That’s around 4.5kmpl less than the claimed mileage with highway driving.

Here’s how these real-world mileage figures would translate into a mix of both city commutes and highway cruising:

The diesel-engined variant delivers an extra 4kmpl over the petrol-engined variant on average. When driven predominantly in city traffic, the Nios’ mileage is just under 16kmpl for the petrol and just under 20kmpl for the diesel. However, if your commute involves more highway driving than in the city, you can expect a mileage of well over 17kmpl from the petrol Nios and over 21kmpl in the diesel.

If driven in equal parts through city traffic and highway cruising, the Grand i10 Nios can deliver between 16-17kmpl with a petrol engine, and over 20kmpl in the diesel-spec.

Our road test teams drive cars with a gentle foot while testing fuel efficiency so it’s expected that your figures might deviate from our tested figures. Fuel efficiency figures also depend on the driving style, car and road conditions.
