The automotive industry in Sweden is mainly associated with passenger car manufacturers Volvo Cars and Saab Automobile but Sweden is also home of two of the largest truck manufacturers in the world: AB Volvo and Scania AB. The automotive industry is heavily dependent on export as some 85 percent of the passenger cars and 95 percent of the heavy vehicles are sold outside of Sweden. The automotive industry and its sub-contractors is a major part of Swedish industry. In 2011 around 110,000 people were employed and the export income of 150 billion SEK accounted for 12 per cent of Sweden's export income. During 2009 128,738 passenger cars and 27,698 heavy vehicles were built in Sweden. Koenigsegg is also a famous swedish company which makes some of the fastest cars in the world, but also some of the most expensive. They currently produce models such as the Jesko, Gemera, and CC850.

They planned to use it for transportation between their home in Ystad and their summer house outside town. The automobile was destroyed in Sweden's first automobile accident but the Cederholm brothers soon built a second, improved version of their steam car reusing many parts from the first one. The car is preserved in a museum in Skurup. In 1898 Gustaf Erikson at Surahammars Bruk built an automobile with an internal combustion engine for Vabis in Södertälje. Erikson continuously improved his car until Vabis was satisfied, and started production of automobiles and trucks in 1902. Harald Håkansson built the first electric car in Sweden on behalf of AB Atlas in 1900. The project never went beyond this single prototype. The bicycle manufacturer Maskinfabriks-aktiebolaget Scania in Malmö started producing automobiles and trucks in 1902. The company amalgamated with Vabis in 1911, creating Scania-Vabis.
