And how does the i20 N Line’s fuel efficiency stack up in real world driving?

With a 1.0 liter turbocharged engine the i20 N Line offers a balance of performance and efficiency. Official numbers are impressive, but real world experiences are often quite different. The car's fuel efficiency is variable, according to owners and reviewers, who differ on whether the car can really use that much fuel in certain driving conditions and whether the improvement in fuel economy has really proved. For the discussion, there are city vs highway driving, driving style and traffic conditions etc. Then there is comparison with the fuel efficiency of the standard i20 and other cars in the segment. Some say the sportier nature of the N Line means they consume a lot more fuel, while others say they can get good efficiency with careful driving.
