Which engine should I choose for high motorway mileage?

I travel more than 20,000 miles per annum on a motorway.

What is a GDI engine? How does it compare to other 1.4 i20s and diesel CRDi for fuel economy and reliability?

The last-generation Hyundai i20 was initially offered with a naturally-aspirated 1.4-litre petrol engine. This felt quite underpowered compared to the punchy 1.0-litre turbocharged petrol that replaced it. We'd recommend a diesel for your miles - it'll be more efficient and ought to be very reliable.
