•6wI am planning to buy the Tata Harrier petrol automatic variant, but I am concerned about its fuel efficiency. Could you please advise on the real-world mileage and whether it is a good choice to buy?

We haven’t yet tested the Tata Harrier petrol automatic for real-world fuel efficiency, though we plan to do so soon. The official lab-certified figures are also not available at this stage, and it’s worth noting that those tend to be optimistic compared to everyday conditions.
Based on its specifications, a 1.5-litre turbocharged engine paired with the Harrier’s substantial size and weight, we expect fuel consumption to be on the higher side. You can reasonably anticipate single-digit mileage in urban conditions, with highway figures improving to the low double digits depending on driving style and traffic.
In short, efficiency isn’t likely to be the Harrier petrol’s strongest suit; it’s more about smooth performance and size. If fuel economy is your top priority, you may want to wait for our full road test results or consider smaller and lighter alternatives.

•6wFuel efficiency of Tata Harrier petrol version would be better than XUV 700 petrol, as harrier has 1.5 litre engine where as XUV 700 has 2 litre engine. This same Harrier engine is being used in Tata Sierra in lower tune and its showing good mileage figures in Sierra. So check XUV 700 petrol fuel efficiency and add 2 to it, this is approximate value. For example, If 700 is giving 12 mileage in highway, then Harrier would give 14 mileage. This is just an example.
