Diesel car drivers across England are confronting a rapidly shrinking market, with new data revealing a dramatic decline in available models as manufacturers pivot decisively towards electric vehicles.
The Vanishing Diesel Fleet
Concerning new research indicates that only 13 of the UK's 30 most popular car manufacturers currently offer diesel vehicles for sale. This represents a staggering reduction from just five years ago, with merely 57 new diesel models remaining on the market compared to 167 models available in 2020.
The Society of Motor Manufacturers and Traders (SMMT) reports that diesel sales are in freefall, with just 12,609 new models registered in September 2025 alone. This figure marks a substantial 28.2% decrease compared to the same period last year, while petrol, hybrid, plug-in hybrid and fully electric vehicles all demonstrate significant growth.
Industry Experts Weigh In
Chris Knapman, editorial director of CarGurus UK, commented that this research underscores the 'rapid decline' of new diesel vehicles throughout the country. He noted: 'For these buyers, the used car market continues to offer a broad range of diesel models, including many that meet Ulez requirements.'
Knapman added: 'For new car buyers, while the choice of diesel models has narrowed significantly, brands like Mercedes are pairing diesel with plug-in hybrid technology for added efficiency and Ulez compliance.'
Holdouts and Future Prospects
Despite the overwhelming trend away from diesel, some manufacturers maintain commitment to the technology. Mercedes-Benz has emerged as the market leader with 16 diesel models available - an increase from 13 last year - primarily due to its expanding range of diesel plug-in hybrids (PHEVs).
French manufacturer Citroën has also refreshed its diesel engines, signalling ongoing investment in cleaner diesel technology. However, these exceptions highlight the broader industry movement as carmakers worldwide redirect resources toward electric and hybrid powertrains.
The 66% decline in available diesel models over five years appears likely to continue as consumer preferences evolve and environmental regulations tighten, potentially making diesel vehicles an increasingly rare sight on British roads.
