Minor changes to the aerodynamics and engine of the Hyundai i20 have resulted in a boost in fuel efficiency for all engines.

The 1.2-litre petrol engine, drops its emissions by 5g/km to 119g/km. This results in a tax disc costing just £30 and company car tax benefit-in-kind rates of just 10%.

The Style models have dropped by 13g/km to just 129g/km. This results in a drop of two Vehicle Excise Duty bands and a 4.3mpg improvement.

The two diesel engines also see significant savings, with the 75PS model dropping by 6g/km to just 110g/km. The 90PS version gains a six-speed gearbox which helps it achieve a 7.2% improvement in fuel economy.

These improvements have been made possible by adding a small spoiler to the underneath of the car to improve airflow around the wheels, fitting an Eco Drive indicator in the instrument panel to suggest the best point to change gear, using low friction engine oil and an alternator management system.
