Feeling the pinch and think a small diesel is the cheapest way to cut your fuel bills down to size? Think again.
A diesel car with lower fuel consumption doesn’t always make financial sense, as you could pay more for it in the first place than it’ll save you long term in cheaper fuel bills.
As the price gap between the two fuels continues to increase, diesel drivers must pile on the miles to avoid footing higher bills. Diesels command a premium price from new, and cash-strapped drivers should think carefully before ditching their petrol cars to save money.
We pitted six popular diesel city cars against their similar-sized petrol siblings to see how many miles it takes to get the extra cash back through fewer trips to refuel – some will take over ten years and one never recoups the initial outlay.
All figures are based on an average mileage of 10,000 miles per year. Those who cover higher mileages stand to get to the break-even point more quickly.
