Plug-in hybrid cars (PHEVs) have grown in popularity in recent years, as drivers seek to change to electric motoring. It’s easy to see why. Hybrids currently offer the best of both worlds, giving buyers the confidence of having an engine for longer ranges, whilst also providing an electric battery for shorter journeys like around town. PHEVs can help increase your fuel economy, lower your running costs, and decrease CO2 emissions. The best plug-in hybrid cars offer all this and have their own selling points too.

And today, there is a plug-in hybrid to suit the needs of nearly every driver. On the used and new car market, you can find a plug-in hybrid version of small hatchbacks, large SUVs, and even sports cars. In addition, plug-in hybrids make fantastic company cars as well. Hybrids low CO2 emissions equal a lower Benefit-in-Kind tax band, and subsequently cheaper company car tax bills. Unsurprisingly, many businesses are now pushing their employees towards PHEVs.

So if you’re looking to buy a hybrid car, join us as we round up our top 10 best plug-in hybrids on sale today. We’ll look at what you can expect to pay on the used and new market, each car’s electric only range, the vehicle’s CO2 emissions, and a whole lot more.

A quick note, many PHEVs can be eligible for the government’s £2,500 plug-in car grant. Find out more about the grant and whether your preferred model is eligible at
