The Tata Nexon iCNG is the primary turbocharged CNG car bought in India with a factory-fitted CNG package. Out there in all variants, the CNG vary is priced between Rs. 8,34,990 for the bottom trim and Rs. 13,29,990 for the top-spec Fearless+PS trim, priced at a premium of between Rs. 70,000 and Rs. 1,15,000 over comparable petrol variants.
We have now put the Tata Nexon iCNG to the take a look at to see the way it fares.
- Will get twin-CNG tanks positioned beneath the boot flooring
- Has an ARAI-claimed effectivity of 24km/kg
- High-spec variant has a kerb weight of 1,398kg
Tata Nexon iCNG real-world gasoline effectivity defined
Powering the Nexon iCNG is a 1.2-litre, three-cylinder turbo-petrol engine as seen within the common Nexon and is paired to a six-speed guide transmission. Whereas the torque stays the identical because the petrol unit at 170Nm, energy is down by 20hp within the CNG model, now producing 100hp. It includes a twin-tank CNG system with a capability of 60 litres or 9kg, well positioned beneath the boot flooring to unencumber a decent 321 litres of baggage area.
In our checks, the Nexon iCNG delivered 15.1km/kg within the metropolis and 23.7km/kg on the freeway, for a mean general real-world effectivity of 19.4km/kg. What’s commendable is that its freeway effectivity is near its ARAI-claimed effectivity of 24km/kg.
When refilled from empty, we managed to fill 7.5kg of CNG versus Tata’s declare of 9kg. CNG filling is dependent upon ambient temperature and pump stress, so beneath optimum situations, attaining 8.5-9kg ought to be doable.
With the general common gasoline effectivity of 19.4km/kg, you possibly can count on a real-world vary of 145-160km on a full tank of CNG.
Autocar India’s fuel-efficiency testing
Since CNG tanks are harder to fill constantly attributable to variables equivalent to ambient temperature and pump stress, we didn’t use our commonplace tankful-to-tankful methodology. As a substitute, for our real-world checks, we emptied the CNG tank and refilled it with 2kg of CNG. We then drove the car in metropolis situations till the gasoline was exhausted. The identical course of was repeated for the freeway run. All through each checks, the Nexon iCNG was pushed completely in CNG mode.
Earlier than our real-world gasoline effectivity checks, we preserve tyre pressures primarily based on the producer’s suggestions. These vehicles are pushed in mounted metropolis and freeway loops in and round Navi Mumbai, and we preserve sure common speeds. All through the checks, there is just one particular person in every automotive, and the aircon is ready to 22deg C in full-auto mode. We function different electricals, such because the audio system, indicators and wipers, similar to a daily consumer would. Periodic driver swaps additional neutralise variations in driver patterns.
