Diesel cars have faced criticism lately, but they’re still a smart choice for drivers who do a lot of miles. Despite their older versions being more polluting, modern diesel engines are just as clean as petrol ones. Plus, they offer lower fuel consumption, which makes them a popular choice for motorway driving and among company car drivers. Even with the negative talk, the best diesel cars are still in demand.

If you have a soft spot for these vehicles, too, we’ve listed some of the best used diesel cars. And to make your purchase stress-free, Carplus offers expert assistance and great terms to help you secure the deal.

TheBMW 3 Seriesis a top pick for the best used diesel car. The 181hp 320d offers more power than other diesels (316d and 318d) while still being fuel-efficient.

Aside from the rear-wheel diesel car, the 3 Series has a smart all-wheel-drive system that efficiently distributes torque between the front and rear wheels.

The most economical option is the 320d in EfficientDynamics form, with an official economy figure of 72.4mpg. The normal 320 used diesel cars achieve 60.1mpg. In terms of emissions, the model emits 124g/km (102g/km in ED form).

SegmentBudget-conscious

For those considering a used diesel car, theAudi A4, with its 2.0 TDI diesel engine, is worth a look. It offers good performance and fuel efficiency. The variant averages 50mpg in NEDC tests and is cost-effective to run, with tax costs under £30. Budget-conscious buyers will appreciate the 2.0-litre Ultra for its eco-friendly emissions — less than 100g/km of CO2.

The A4, like many diesel cars, excels on the motorway and provides a comfortable ride with low levels of road and wind noise. Certain A4s have firm suspension, but optional adaptive dampers can help.

3. Volkswagen Golf (2.0 TDI)

SegmentBudget-conscious

TheVolkswagen Golf, especially the 2.0 TDI, is highly regarded as one of the best diesel cars. It offers strong performance, even in the entry-level model, and provides relaxed driving even at low revs.

The Golf’s diesel cars include the 113hp 2.0 TDI 115, 148hp 2.0 TDI 150, and the sporty 2.0 TDI 200 GTD. The GTD variant offers brisk acceleration, although not as quick as a hot hatch. The 115 achieves over 65mpg in real-world testing.

Thanks to VW’s build quality, it remains a solid choice for daily transportation for many years.

SegmentBudget-conscious

TheFord Focuswith a 1.5 TDCi engine is very efficient — it easily achieves over 50mpg even in city traffic. It can also handle long journeys with a range of around 60 miles on just a light.

The Focus admittedly lacks some of the revvy nature of its petrol counterpart. But the diesel engine shows its talent in motorway overtaking. Its 120hp and 300nm of torque from low revs offer a smooth and relatively quiet ride reminiscent of a petrol engine. The model is perfect at agile handling, so owners of these used diesel cars will feel confident at the wheel.

5. Mercedes-Benz C-Class (C220d)

SegmentBudget-conscious

TheMercedes-Benz C-Class C220dis one of the best used diesel cars, and here’s why. It has a powerful 2.0-litre engine that delivers 200hp, which makes it quick off the mark with a 0-60 time of 7.3 seconds. It has slightly less power than the petrol. Still, you can expect it to feel punchier thanks to its low-end torque, which is handy for overtaking on the motorway. Plus, it’s as quick as the BMW 320d.

In terms of smoothness, these diesel cars are comparable to others in the market. When it comes to fuel economy, the C220d beats both the A4 and 3 Series equivalents, and its road tax is reasonable for small cars at £190.

TheVauxhall Insignia (2.0 CDTi)offers a solid build, refined driving, and reasonable running costs. This diesel car is powered by a 167hp 2.0 CDTi engine, which delivers notable acceleration and flexibility. Although it can be noisy on startup, it runs smoothly afterwards.

The fastest option, the 192hp 2.0 CDTi Bi-Turbo, was discontinued in 2015. But in recent years, the 2.0 CDTi model with ecoFLEX technology has been good value for money. It achieves 114g/km and a fuel economy of 65.7mpg.

The D4 engine offers ample power for everyday driving. The top speed is 143mph, and the 0-60 time is 7.1 seconds, whether you opt for the 6-speed manual or 8-speed automatic transmission. Additionally, if you need your diesel cars to tow, the D4 AWD model can handle weights of up to 1,900kgs.

TheToyota RAV4 (2.2 D-4D)comes with a 148bhp 2.2-litre diesel, which offers decent power and torque. The model returns up to 50.4 and emits 149g/km of CO2. It’s a bit thirstier than the 2.0 diesel car but equipped with four-wheel drive for added capability.

The RAV4 accelerates from 0-60 in 9.3 seconds with 400nm of torque. It can reach a top speed of 124mph and excels off-road. The ride might feel firm in city driving compared to other used diesel cars, but it softens up at higher speeds.

The back seats offer ample legroom, slightly at the expense of boot space. Also, the car is known for being dependable and shouldn’t break the bank to service.
