On the WLTP combined cycle, the plug-in hybrid Range Rover Sport returns 75.3-86.9mpg.

In reality, economy depends on how often it can be recharged, but those are exceptional figures for a car this quick and heavy.

And it is indeed quick, towing a twin-axle Swift caravan from 30-60mph in 8.6 seconds.

Foot to the floor, the four-cylinder petrol engine is rather vocal, but driven gently, it wafts along quietly.

At motorway speeds, the Range Rover Sport is secure. There’s barely a twitch from the caravan in your towing mirrors.
