Diesel cars, though their sales have declined in recent years, still offer impressive efficiency and remain crucial in the UK’s transition to emission-free transport. Modern diesel vehicles are far cleaner than their predecessors, thanks to technologies like diesel particulate filters (DPFs) and diesel exhaust fluid (AdBlue), which significantly reduce harmful emissions. With their low CO2 emissions compared to petrol engines, diesel cars continue to be a key part of reducing reliance on oil and moving towards a more sustainable future. Here are some of the most economical diesel cars currently on the market.
