The Hyundai i40 is thinking big – in every way. The Korean manufacturer offers estate and saloon versions that appeal to families and company car buyers alike by offering plenty of space and excellent economy on top of bold looks. There are a range of diesel and petrol engines available in the Hyundai i40 line-up, with our favourite being the 1.7-litre diesel. It's quick, and can do an impressive 62mpg – which makes this one big car to look out for.
