Cheap to buy and run, well-equipped, neat styling.
Noisy diesel engine, cheap-feeling dash, iffy ride.
Not as good to drive as a Fiesta, but impossible to rule out i20's superior value.
Best for running costs is the 74bhp 1.4-litre diesel. It is gruff, but in the i20 it helps the Hyundai average a stunning 64.2mpg while emitting just 116g/km of carbon dioxide. That means it easily slots into VED Band B, while company users pay 13% benefit-in-kind.
The petrol range is less impressive, chiefly because the 1.2-litre doesn't slip into the VED Band B with its emissions of 124g/km. In any case, the 54.3mpg official fuel consumption figure isn't bad.
The most powerful 99bhp 1.4, meanwhile, averages 50.4mpg while polluting just 133g/km of CO2.
