It's important to note that there are other inventors who contributed to the development of the internal combustion engine before Benz. For example, Émile Lenoir built a gas-powered engine in 1860, and Siegfried Marcus developed a similar engine in 1864. However, these engines were not as efficient or reliable as Benz's design.
Ultimately, Benz's Motorwagen is considered the first true car with an internal combustion engine, revolutionizing transportation and paving the way for the modern automobile.
