Diesel cars are retreating from UK roads at a startling pace as buyers increasingly choose electric alternatives. New industry data paints a bleak picture for diesel’s future, showing steep drops in market share, model availability and public confidence since the Dieselgate scandal.
How fast diesel is shrinking in the new-car market
Recent figures show diesel’s share of new registrations has plunged from being dominant a decade ago to a small fraction today. Analysts now predict diesel could form only a sliver of new-car sales within a few years.
- Current share: diesel accounts for roughly one in every 17 new cars sold.
- Near-term forecast: some projections put diesel market share at around 2% by 2028.
- Model choice: the number of new diesel models available has fallen to about 91, down from roughly 240 ten years ago.
Why drivers are turning away from diesel
Trust hit by Dieselgate and reputation damage
The Volkswagen emissions scandal left a long shadow over diesel. Revelations that some manufacturers manipulated tests dented consumer trust. That reputational damage still affects buyer decisions.
Policy, costs and cleaner alternatives
Several forces are nudging drivers towards electric vehicles and hybrids.
- Government policy: incentives and the planned 2035 ban on new petrol and diesel cars shift fleet and retail choices.
- Running costs: diesel often costs more at the pump and can attract higher taxes for the most polluting models.
- Urban charges: Clean Air Zones and London’s Ultra Low Emission Zone make diesel ownership less attractive in cities.
- EV improvements: better battery range and falling prices make electric options more practical for many buyers.
Commercial vehicles: diesel’s last stronghold is fraying
Diesel still dominates vans and larger light commercial vehicles, but electrification is growing fast in this sector too.
- Market share: a large majority of light commercial vehicle sales this year have been diesel — figures around 85.5% have been reported.
- EV growth: electric vans under 3.5 tonnes have seen sales rise sharply, while heavier small LCVs have recorded even larger percentage gains.
Used values and residual strength of diesel models
Despite falling new-sales numbers, diesel retains value in the secondhand market. Buyers still prize diesel for economy and range in certain use cases.
- After two to four years, diesel cars typically keep about 51% of their original price.
- For comparison, hybrids hold roughly 53%, petrols about 58%, while battery EVs are near 36%.
- This stronger residual value reflects diesel’s appeal where range and towing matter.
How manufacturers and the industry are responding
Automakers are cutting back on diesel development and model releases. Fleet buyers who once favoured diesel because of tax rules are switching to electric alternatives.
Auto Express and industry editors note the shift is being driven by changing incentives and improvements in hybrid and EV technology. Some manufacturers are prioritising electrified lineups over diesel variants.
Regulation and the uncertain timeline for diesel’s decline
Legislation could accelerate diesel’s exit, but the tempo of decline depends on many variables.
- Stronger emission rules or broader clean-air charging could hasten diesel’s fall.
- Conversely, continued strong used values and specific commercial needs may slow a complete disappearance.
What these trends mean for drivers and buyers
Consumers weighing a new vehicle purchase must balance upfront cost, running expense and likely future restrictions on diesel access. For many drivers, electric cars now offer a credible alternative to diesel, both in city and fleet use.
