1. Suzuki Ignis 1.2 SHVS

Official fuel economy: 65.7mpg; True MPG: 59.6mpg; Shortfall: 9.3%

This version of the Ignis, which does not have four-wheel drive, is the most efficient SUV we've ever tested. It's a mild hybrid, which means a small electric motor works alongside its 1.2-litre petrol engine, helping to get you moving and reducing the strain on the engine. Even if you decide four-wheel drive is a must, the average Truem MPG only drops to 53.3.

Worst real MPG SUV tested so far

Audi SQ5

Official fuel economy: 33.2mpg; True MPG: 24.6mpg; Shortfall: 25.8%

It's perhaps unsurprising that a performance SUV takes our bottom slot here, but while it might not be very economical, there's plenty else to like about Audi's hot Q5. For starters, there's its 3.0-litre turbocharged V6 petrol engine – which, combined with its classy and practical interior and comfortable long-distance ride, still makes for a formidable package. Just expect tovisit the petrol station quite often.
