AutoTrader’s data points to diesel decline as fuel costs push buyers toward EVs

CEO George Mienie says a -18% drop in diesel enquiries, alongside rising demand for electric and hybrid vehicles, suggests South African motorists are starting to rethink traditional powertrain choices.

The unintended consequence of South Africa’s fuel crunch may be doing what policy and incentives have long struggled to achieve: pushing more motorists to consider electric vehicles over diesel.

According to George Mienie, CEO of AutoTrader, the platform’s latest on-site data suggests the market may already be starting to shift.

Diesel Demand Declines As Consumer Behaviour Shifts

Over the past four weeks, enquiries for diesel-powered passenger vehicles have declined by -18% compared to mid-February, a notable change in a country where diesel has long been a preferred option for motorists focused on fuel efficiency and long-distance driving.

For years, it has occupied a comfortable middle ground between affordability, performance and range. But when fuel prices rise sharply, that equation starts to change. And consumers appear to react immediately.

Rising Interest In Electric And Hybrid Vehicles

At the same time, interest in alternative technologies is rising sharply. Searches for battery electric vehicles are up +45% over the same period, while hybrid searches are up +16%, although that marks slower growth for hybrids than previously seen.

Together, these shifts suggest that rising fuel costs are pushing many South Africans to reconsider their reliance on traditional fossil fuels.

What makes this shift more telling is that it is not just showing up in search behaviour. Demand is translating into action. Consumers are not only searching for alternatives, but also engaging with them more seriously as running costs come under pressure.

Supply Constraints Begin To Emerge

What is particularly notable is that this growing demand for battery electric vehicles is not yet being matched by stock availability.

BEV listings are down -3% even as demand has risen sharply, pointing to a market where supply may already be tightening. That could reflect existing stock being bought up more quickly, while some current owners choose to hold onto their BEVs as fuel prices climb.

By contrast, diesel, petrol and hybrid stock supply have all edged higher. That suggests supply in the traditional market remains available, even as buyer attention begins to move elsewhere.

Market Implications And What Comes Next

It is that disconnect between shopper behaviour and available stock that makes this moment worth watching.

If demand for BEVs continues to rise while listings remain constrained, the used market could feel the effects first. Tighter supply and growing demand would likely put upward pressure on prices, particularly for well-priced second-hand electric vehicles.

None of this means diesel is disappearing overnight, or that South Africa has suddenly become an electric vehicle market. But an -18% change in diesel enquiries over four weeks is a meaningful signal, especially when it is happening alongside stronger interest in electric and hybrid alternatives.

If these trends continue, rising fuel costs may do more than squeeze household budgets. They may also have the unintended consequence of quietly accelerating South Africa’s shift towards full battery electric vehicles.
