Will a Hyundai i40 cost more to run than my Golf?

Hi, I'm thinking of changing my car. It's a 2008 Volkswagen Golf 1.4 petrol and I'm thinking of buying a Hyundai i40 1.7 diesel. As this is a bigger car does that mean it would cost more to run on fuel than my own car?

Hi Irene,

Engine size means less than it used to, especially when comparing a petrol engine to a diesel one. That Hyundai will be more economical and cheaper to tax than the 1.4 petrol Golf from 2008. Saying that, if most of your driving is in town there won't be a big advantage for the diesel, but it should still use less fuel overall.

A larger car such as the i40 is likely to be a bit heavier on things like tyres, but it's newer than your Golf so shouldn't need tyres for a while. 

Hope that all helps
