Hyundai i20 running costs are very reasonable. The i20 is well equipped, good value and cheap to run too. The five-year unlimited mileage warranty means any unexpected costs are taken care of – plus this can be transferred to a new owner should you decide to sell. Servicing is very reasonable at Hyundai dealers and fuel economy on all models is impressive.

The diesels are also cheap to tax and capable of 67.3mpg. In 2012 the Hyundai i20 receieved a facelift and the range was also boosted by a new engine. The 1.1-litre diesel has a combined fuel economy of 74.3mph making it the most frugal engine on the range.

Hyundai i20 emissions are low, although it’s disappointing that the original entry-level 1.2-litre engine didn’t emit less than 120g/km of CO2, which would have made it cheaper to tax. From July 2010 upgrades to aerodynamics and the engine did drop this model to less than 119g/km. However, its economy remained at a useful 54mpg. The diesel engine is the most efficient though – from launch both the low- and high-power versions were capable of 64mpg and emitted 116g/km and 118g/km of CO2 respectively.

The improvements made in 2010 meant economy for both went to 67.3mpg and the emissions dropped to 110g/km for the lower-powered model and 111g/km for the higher-powered engine. By adding the 1.1-litre diesel to the i20 range this made it the greenest engine on the range. It emits 84g/km of C02.

There’s little to worry you about Hyundai i20 reliability either. The firm has a good reputation for mechanical robustness and the five-year unlimited mileage warranty means there’s no need to worry about any unexpected bills for a large chunk of the car’s life.
