The first true automobile, as we recognize it today, was built by Karl Benz in 1885-1886. This vehicle, the Benz Patent-Motorwagen, is widely credited because it was the first designed around an internal combustion engine (an engine that generates power by burning fuel inside the engine itself) and was a fully integrated, self-propelled vehicle, not a horse carriage with an engine bolted on. While other inventors created steam-powered road vehicles earlier, Benz's design established the core architecture for all future gasoline-powered cars.
Benz's creation was a three-wheeled vehicle featuring a single-cylinder, four-stroke engine. A key innovation was his use of a lightweight steel tubular frame and wire-spoke wheels, which was revolutionary for the time. The engine produced roughly 0.75 horsepower, allowing the Motorwagen to reach a top speed of about 10 miles per hour. Benz received the patent for his "vehicle powered by a gas engine" (DRP No. 37435) in January 1886, a date considered the official birth certificate of the automobile.
It's important to acknowledge precursors. In the late 18th century, Nicolas-Joseph Cugnot built a massive steam-powered tractor for hauling artillery, but it was impractical for personal transport. Throughout the 19th century, various "horseless carriages" powered by steam or electricity were developed. However, Benz's Patent-Motorwagen was the first to combine a practical internal combustion engine with a purpose-built chassis, making it a viable product. His wife, Bertha Benz, famously demonstrated its practicality by undertaking the first long-distance road trip in 1888, secretly driving it with her sons about 65 miles to visit her mother, a publicity stunt that proved the car's reliability.
