* Karl Benz's Patent-Motorwagen (1886): This is often cited as the first practical automobile. It was a three-wheeled vehicle powered by an internal combustion engine. Many consider this the first true automobile.
* Gottlieb Daimler's and Wilhelm Maybach's vehicles (late 1880s): Daimler and Maybach developed high-speed internal combustion engines that were adapted to various vehicles, including a four-wheeled carriage. Their contributions were crucial to the development of the automobile.
The distinction often comes down to whether you prioritize the first *self-propelled vehicle*, the first vehicle with an *internal combustion engine suitable for practical use*, or the first vehicle resembling a modern *car* in design. Benz's Patent-Motorwagen is generally the most widely accepted answer due to its practicality and documentation.
