Audi Q2 vs DS 4 Crossback vs Seat Ateca

7. Seat Ateca 1.6 TDI 115

True MPG: 50.2mpg

The Ateca is one of the most enjoyable SUVs to drive and a former What Car? award winner. We're particularly keen on the turbocharged 1.5-litre petrol model, but the 1.6-litre diesel is the most efficient option, with a real-world average of 50.2mpg.

New Kia Picanto X-Line and Vauxhall Viva Rocks vs Suzuki Ignis

True MPG 50.9mpg

Don't be fooled by the Ignis's small size – this is a seriously impressive car. It's deceptively spacious, offers a generous amount of equipment and is very cheap to buy and run. This isn't even the most efficient version, as we'll explain later.

5. Kia Sportage 1.7 CRDi 

Kia Sportage

True MPG 51.4mpg

Kia's Sportage gives you a lot of equipment for a very reasonable price, especially if you go for our recommended 2 trim level. It's also a practical choice and the 1.7-litre diesel engine is capable of 51.4mpg. Just don't expect the Sportage to be particularly refined or enjoyable to drive.
