The term automobile is used par excellence to refer to passenger cars. In a more generic definition, it refers to a self-propelled vehicle intended for the transport of people or goods without the need for lanes. There are different types of cars, like trucks, buses, vans, motorcycles, motocarros or quads. The first car with internal combustion engine is attributed to Karl Friedrich Benz in the city of Mannheim in 1886 with the Benz Patent-Motorwagen model. Soon after, other pioneers such as Gottlieb Daimler and Wilhelm Maybach presented their models.
