what did the first car run on

[BeauLynn]

The first true automobile, Karl Benz's 1886 Patent-Motorwagen, ran on ligroin, a light petroleum product similar to what we now call gasoline or naptha. It was chosen because it easily vaporized for the engine's primitive surface carburetor. This single-cylinder, four-stroke engine produced about 0.75 horsepower and achieved a top speed of 10 mph (16 km/h).

The choice of fuel was a critical engineering challenge. Early internal combustion engines experimented with various fuels, including coal gas and hydrogen. Ligroin, a byproduct of refining kerosene from crude oil, was relatively volatile and readily available at the time from pharmacies as a cleaning solvent, ironically making it one of the first "gasoline" stations.

Here’s a comparison of early automotive power sources for context:

Vehicle / Inventor	Year	Primary Power Source	Key Characteristics
Karl Benz Patent-Motorwagen	1886	Ligroin (Gasoline)	First true automobile; internal combustion engine.
Gottlieb Daimler Motorized Carriage	1886	Petroleum Spirit	Another early gasoline engine pioneer.
Early Predecessors
Nicolas-Joseph Cugnot's Fardier	1769	Steam	First full-scale, self-propelled mechanical vehicle; very slow and impractical.
Carl Benz's earlier prototypes	1885	Coal Gas	Used a lighter-than-air fuel gas; impractical for a range of vehicles.

While steam-powered vehicles existed earlier, Benz's Patent-Motorwagen is widely recognized as the first automobile designed from the ground up to be powered by an internal combustion engine running on a petroleum-based liquid fuel, setting the standard for the next century of automotive development. The move to liquid fuel was essential for giving vehicles the range and practicality needed for personal transportation.

It ran on gasoline, pretty much. Well, a specific type called ligroin. Back in 1886, Karl Benz built this three-wheeled thing called the Patent-Motorwagen. Gas stations didn't exist, so you'd actually buy the fuel as a cleaning fluid from a pharmacy. It's wild to think that the whole car industry started with something so simple you could pick it up next to the soap. It only had one cylinder and went about as fast as a brisk bicycle ride.

From a historical perspective, the 1886 Benz Patent-Motorwagen used a light petroleum distillate known as ligroin. This substance was a practical choice in an era before dedicated fuel infrastructure. Its significance lies not just in the chemical itself, but in establishing the internal combustion engine's dominance over steam and electric power, which were viable competitors at the time. This decision ultimately shaped the entire trajectory of personal transportation for over a hundred years, locking in our reliance on petroleum-based fuels.

Think of it as early gasoline. The fuel was a clear, volatile liquid called ligroin. The engine was incredibly simple by today's standards—a single piston. It didn't even have a carburetor like modern cars; instead, it used a surface vaporizer where the fuel soaked into a fibrous material to mix with air. It was inefficient and not very powerful, but it proved a liquid fuel could reliably power a vehicle. That basic principle is still at the heart of most cars today, even if the technology has been refined beyond recognition.

My granddad used to talk about the early days of cars. He said the first one, Benz's car, ran on "benzine," which is what some folks called gasoline back then. You couldn't just pull into a station. You'd get it in small cans from the chemist or the hardware store. It makes you appreciate how far we've come. That first car was basically a motorized bench seat, and now we have cars that can almost drive themselves. It all started with that one simple idea: burning liquid fuel in a tiny engine.
