The number of battery electric vehicles (BEVs) on Norway's roads is on track to overtake gasoline cars by the end of this year or early 2025, a first in any country, according to Reuters and analyst calculations.

The change has been driven by generous incentives, thanks in part to Norway's vast oil and gas wealth.

Still, analysts believe it will be a few years before BEVs surpass the number of diesel vehicles in Norway.

The Nordic country of 5.5 million wants to become the first country to stop selling new gasoline and diesel cars by 2025. Nine out of 10 new cars sold earlier this year were BEVs.

If more countries follow Norway's lead, global oil demand could peak sooner than expected. The International Energy Agency expects this peak to be reached before 2030, with cars and vans accounting for more than 25% of oil demand.

However, Norway's transition hasn't been cheap, with the country exempting BEVs from taxes on internal combustion engine cars and investing in public BEV chargers.

According to data from the Norwegian Road Administration seen by Reuters, BEVs accounted for 24.3% of Norway's 2.9 million cars as of March 15, compared to 26.9% for gasoline vehicles.

That represented a lead of almost 76,000 gasoline vehicles – significantly less than the 104,590 new BEVs sold in Norway last year.

“If this (trend) continues over the next 12 months, with sales of pure gasoline cars currently negligible, there will be more BEVs on the road than pure gasoline cars by this time next year, and likely before the end of this year,” said Robbie Andrew, senior researcher at Climate Change Think-Thank CICERO.

With nearly 370,000 more diesel cars on Norway's roads than BEVs, it will likely take three to four years for BEVs to overtake diesel vehicles, Andrew added.

Ingvild Kilen Roerholt, head of transport research at the Oslo-based think tank Zero, also saw the number of BEVs overtaking petrol cars in Norway this year, despite a recent decline in sales.

Sales of new BEVs fell by about a quarter in Norway last year as new car sales generally fell amid rising interest rates and the government cutting some tax incentives.

However, according to the Norwegian Road Association (OFV), the share of BEVs in total sales reached a record 92.1% in January.

In March, that share was 89.3%, while new car sales fell 49.7% year-on-year, the latest OFV data shows.

Last year, the center-left government abolished a sales tax exemption for BEVs that cost more than 500,000 Norwegian crowns ($46,700), making models like the Tesla X and Audi e-tron more expensive.

Still, the remaining tax exemptions for BEVs will cost the state 43 billion crowns in 2023, up from 39.4 billion crowns in 2022, budget documents show.

Despite the recent sales decline, Roerholt said she was “pretty sure” that sales of new BEVs in Norway would exceed 76,000 this year.

She also predicted that the number of BEVs in Norway could exceed the number of petrol and diesel cars combined by 2029.

“For this to succeed, we must achieve the goal of 100% of all new cars being emission-free by 2025,” she added.

The increasing popularity of BEVs has led to a decline in demand for gasoline and diesel.

Sales of diesel and gasoline at Norwegian gas stations have fallen by around 8% since 2021, according to monthly data from Statistics Norway and Reuters calculations. This does not apply to the sale of diesel at truck filling stations.

“It’s still a huge market for fossil fuels. We haven’t seen the biggest drop yet,” Kristin Bremer Nebben, head of fuel dealers association Drivkraft Norge, told Reuters.

Demand for fossil fuels has been supported in part by sales of hybrid cars, which combine a battery with an internal combustion engine powered by gasoline or diesel.

According to data from the Norwegian Road Administration, there were almost 340,000 hybrid cars on Norwegian roads as of March 15, mostly plug-in hybrids with gasoline engines, accounting for 12% of the total fleet.

However, hybrid vehicles have lost market share in recent years as the government has withdrawn incentives.

The Norwegian EV Association expects BEVs to account for 95% of all new car sales this year.
