Most economical SUVs to buy in 2019

Their bulky shapes now contain battery packs: the most economical SUVs have become some of the greenest cars on the road.

Large sport utility vehicles (SUVs) used to be the symbol of extravagance, with climate campaigners taking aim at these tall, imposing, so-called "gas-guzzlers".

But the cars have now been reinvented as eco-champions. As it turns out, their bulky dimensions are ideal for accommodating the large battery packs required for plug-in hybrid cars.

When fully charged, plug-in hybrids can run largely on electrical power for between 20 and 30 miles, making them extremely efficient on shorter journeys. Their advantage reduces on longer trips, however, when the cars run mainly on their petrol and diesel engine.

It's worth bearing in mind if you're considering a plug-in hybrid, as their impressive official fuel economy figures are rarely seen in the real-world. Business users may be more interested in the low carbon dioxide (CO2) emissions, which result in low levels of company car tax.

While the most economical medium- and large-SUVs are hybrid vehicles, the extra cost of the technology means that it's less common on smaller, cheaper SUVs, and so the most efficient of these models are diesel-powered.

We've only selected cars based on the latest, tougher fuel economy test, known as WLTP, which also ensures that cars comply with the latest Euro 6 emissons regulations. This means that any new diesel car (and virtually every new vehicle since September 2015) will avoid new inner-city emissions charges.
