Tesla lost market share in Sweden and Norway in January, car registration data showed on Monday as the U.S. electric vehicle maker faces a test of popularity following billionaire CEO Elon Musk's high-profile foray into politics. A total of 405 new Teslas were registered in Sweden last month, down 44% from January of 2024, while registrations in Norway fell to 689, a decline of 38% over the same period, despite soaring overall demand for cars in the two countries. While Tesla's Model Y crossover SUV was the most sold car in both of the two Nordic countries in 2024, the group's image has taken a hit in recent weeks, a market sentiment survey by Sweden's Novus Group found according to Swedish news agency TT.
