The best diesel cars 2026 – driven, rated, ranked

Diesel seemed to be on its way out a few years ago, pushed to the side in favour of cleaner petrol, plug-in hybrid and electric alternatives. 

Indeed, some car makers are turning their back on diesel: Volkswagen recently announced that it would drop the diesel Golf in the UK, due to a lack of customer demand. 

But while the market share of diesel cars has tailed off dramatically and manufacturers prioritise petrol and electric alternatives, there are still a handful of diesel models worth buying today. 

When it comes to long motorway schleps or towing a heavy trailer, a torquey diesel engine that’s happy to cruise along at under 2500rpm is the ideal choice for high-mileage drivers who need an efficient, dependable workhorse. 

They’re not quite as efficient around town and diesel is dearer than petrol, but for high-milers, those who live rurally and those who want less fuel stops on longer jaunts, the balance often swings back in diesel’s favour. 

Our expert team of road testers have driven and assessed every new diesel car on sale and have helped to put together a list of the top 10 diesel cars on sale right now. 

We think the Skoda Superb is the best diesel car on sale, outshining rivals with its impressive long-range comfort, excellent practicality (particularly in estate form), strong fuel economy and easy-going drivability. It’s also pretty good value for money, too. 

But which other diesels should you consider? If you’re after a luxury car that can tow a trailer or caravan effortlessly, a straight-six BMW X5 might appeal more. If you’re after a family car that promises a strong economy, the Skoda Kodiaq has the efficiency, as well as the load-lugging ability to slot into everyday life.
