Most economical SUVs to buy in 2019

SUVs are often big and heavy, but they can still be economical. Check out the greenest SUVs with petrol, diesel and hybrid power

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

However, many SUVs have been reincarnated in smaller sizes with fuel-sipping petrol and diesel engines, with a number of larger models gaining plug-in hybrid power to allow zero-emission driving around town. This means that many buky 4x4s have become plug-in hybrid cars possible of cruising around town without belching out polluting fumes.

When fully charged, plug-in hybrids can run largely on electrical power for between 20 and 30 miles when driven gently, making them extremely efficient on shorter journeys - especially low-speed trips. Their advantage disappears on longer trips, however, when the cars run mainly using their petrol or diesel engines, with the extra weight of the hybrid kit potentially even reducing economy once the batteries have been depleted.

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 - unless you only do short journeys and religiously charge the batteries once they go flat. 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 this tech is 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.
