Traditionally, Dutch BEV sales show a spike in the last quarter of the year. This is followed by a trench in the first quarter. Sales of fossil fuel vehicles follow the opposite trend. Low sales in the last quarter followed by high sales in the first quarter.
Previously, the high market share of BEVs just before year’s end was in part made possible by the fossil fuel market delaying deliveries until the new year. When one is high and the other is low, you get a brilliant ratio. But in the first quarter, fossil fuel vehicle sales were very high, and still BEV market share was extremely high.
By the way, this was the first Q1 in 5 years that FFV registrations grew. And it is likely only because better supply enabled carmakers to deliver orders from their large backlogs, not because of an increase in demand.
