The number of diesel cars available in UK showrooms has dropped dramatically, with just 57 models on offer in 2025 compared to 167 in 2020 — a staggering 66% decline.
Once a popular choice for long-distance drivers and fleet buyers, diesel is rapidly losing ground to electric and hybrid alternatives. Manufacturers are phasing out diesel options in response to changing consumer demand, stricter emissions regulations, and the upcoming 2035 ban on new petrol and diesel car sales.
Diesel Cars: From Dominance to Decline
Once the go-to choice for long-distance drivers and fleet buyers, diesel cars are now becoming a rare sight in UK showrooms. According to new analysis from CarGurus, the number of diesel-powered models available from mainstream brands has dropped from 167 in 2020 to just 57 in 2025 — a staggering 66% decline.
This dramatic shift reflects a broader change in consumer habits, government policy, and manufacturer strategy. Diesel’s fall from grace began with the Dieselgate emissions scandal in 2015, but the pace of decline has accelerated as electric vehicles (EVs) and hybrids take centre stage.
Why Diesel Is Falling Out of Favour
Several factors are driving the collapse of diesel car availability:
- Environmental concerns: Diesel engines emit more nitrogen oxides (NOx), which contribute to air pollution. Cities like London have introduced low-emission zones that penalise older diesel vehicles.
- Government policy: The UK plans to ban the sale of new petrol and diesel cars by 2035, pushing manufacturers to phase out diesel options early.
- Consumer sentiment: Buyers are increasingly wary of diesel’s reputation, with many opting for cleaner alternatives.
According to Motoring Research, diesel’s market share has plunged by 87% over the past decade. In 2015, diesel cars made up nearly half of all new registrations. By 2024, that figure had dropped to just 6%.
Showroom Reality: Fewer Choices, Fewer Brands
If you’re in the market for a new diesel car, your options are shrinking fast. Many mainstream brands — including Honda, Volvo, and Toyota — have completely dropped diesel from their UK line-ups. Others, like Ford and Vauxhall, offer only a handful of models.
Interestingly, one brand is bucking the trend. According to This is Money, BMW still offers 16 diesel models in its showrooms, catering to drivers who value torque, fuel economy, and long-range capability.
But even these options may not last. Industry forecasts suggest diesel could make up just 2% of new car sales by 2028, meaning only one in 50 cars sold will run on diesel.
What It Means for Drivers
For current diesel car owners, the shift raises questions about resale value, running costs, and future restrictions. While diesel engines still offer excellent fuel economy for motorway driving, they’re increasingly subject to higher road tax, ULEZ charges, and insurance premiums.
If you’re thinking of selling your diesel car, now might be the time. As demand drops and regulations tighten, values could fall — especially for older models without Euro 6 compliance.
The Rise of Electric and Hybrid Alternatives
As diesel fades, electric and hybrid vehicles are surging. Manufacturers are investing heavily in battery technology, and the UK’s charging infrastructure is expanding rapidly. According to Advanced Driving, in 2025, EVs accounted for over 20% of new car sales, with hybrids close behind.
For many drivers, the switch is already underway. Whether it’s for environmental reasons, cost savings, or future-proofing, the message is clear: diesel cars are no longer the default choice.
Final Thoughts
The decline of diesel cars in UK showrooms marks a turning point in motoring history. From dominating the market to becoming a niche option, diesel’s fall has been swift and decisive. For buyers, it means fewer choices — and for sellers, it may mean acting sooner rather than later.
If you’re still driving diesel, it’s worth considering your next move. The road ahead is electric — and diesel is running out of fuel.
With diesel cars disappearing from UK showrooms and demand shifting toward electric and hybrid models, now could be the perfect time to sell.
