Crank to Code: Examining the Early Days of Automotive Technology

Today’s cars are equipped with touch screens and advanced safety features. However, they weren’t always as sophisticated. During their early days, automobiles were noisy and unpredictable mechanical machines. Learn more about the early days of automotive technology.

The Invention of the Automobile

One of the first breakthroughs for the earliest automobiles came in 1769 with Nicolas-Joseph Cugnot’s three-wheeled steam-powered vehicle. He built it for the French army as a military tractor. It could only go about 2.5 mph, but it was a groundbreaking invention.

In addition to steam, inventors were also experimenting with other ways to power vehicles. Among the most popular was electricity. Robert Anderson developed an electric carriage in Scotland between 1832 and 1839. Then, William Morrison introduced a six-passenger wagon around 1890, which became the first successful electric vehicle in the U.S. Because they were quiet and free from unpleasant exhaust, these vehicles were popular among urban drivers at the time.

However, gasoline-powered cars pushed automotive technology forward. Karl Benz’s Patent-Motorwagen, created in 1886, was considered the first true automobile. It featured a three-wheeled chassis and an internal combustion engine in a single unit.

Around the same time, other inventors worked on their own engines. Most notably, Gottlieb Daimler and Wilhelm Maybach developed the Cannstatt-Daimler, the first four-wheeled, four-stroke engine. A few years later, the Duryea brothers built the first successful gas-powered car and set up the first car manufacturing company in the U.S.

When Cars Became More Practical

Although cars could travel farther than demonstration runs by the late 1890s, they remained expensive novelties mostly owned by wealthy buyers. Early automobiles were also difficult to control and unreliable on rough roads. Therefore, engineers began focusing on comfort and safety.

Ignition Systems

Starting an early gasoline-powered car was like operating heavy machinery. Drivers would need to manually crank the engine by hand. This was both exhausting and dangerous. If the engine backfired, it could cause broken wrists or arm injuries.

Charles Franklin Kettering helped solve this problem by developing the first electrical ignition system and self-starter for car engines. It replaced the manual crank with an electric motor and turnkey system, and was introduced in 1912 on the 40-horsepower Cadillac Model Thirty.

Pneumatic Tires and Braking Systems

Andre Michelin invented the pneumatic tire for automobiles in 1895, making cars much more capable than they had been before. Later in 1911, Phillip Strauss invented the combination tire and inner tube. This improved comfort on rough roads and allowed cars to travel even faster. However, it also exposed how early braking systems struggled to safely stop heavier, faster automobiles.

Louis Renault’s drum brake and Frederic Wilhelm Lanchester’s disc brake replaced wooden block brakes in 1902. While much more effective, they still relied on mechanical systems using cables and levers. Malcolm Loughed’s 1917 hydraulic brakes offered a solution by using fluid pressure to distribute braking force more evenly and with much greater power.

Automatic Transmission

Shifting gears in early automobiles demanded physical effort, since drivers needed to manually synchronize the speed of the engine and the gears to avoid grinding. The first automatic transmission was developed in 1921 by Alfred Horner Munro, but it was still limited and never became a mainstream success. Almost two decades later, General Motors designed the Hydra-Matic and debuted it in Oldsmobiles for the 1940 model year.

The Assembly Line and Mass Production

Although cars had become reliable machines at the turn of the 20th century, they weren’t yet accessible to ordinary people. This is largely due to the manufacturing method, which required teams of craftsmen to assemble components one by one.

Henry Ford brought cars to the masses with his moving assembly line. Parts could move through a factory on a conveyor system while workers stayed at specialized stations. This approach allowed for multiple cars to be assembled simultaneously.

Ford began using the moving assembly line in 1914 to build magnetos, an important component of the Model T.  He expanded the system to assemble the entire vehicle within the same year. With this system in place, production time dropped from more than 12 hours to roughly 93 minutes. The faster process also dramatically reduced costs, making the Model T affordable to more people. By 1924, it accounted for over half of all cars sold worldwide.

Early Automotive Safety and Driver Innovations

Although early automobiles were exciting, they weren’t exactly comfortable or safe. Manufacturers began introducing features that made driving easier, safer and far more enjoyable. Some of the most noteworthy innovations include:

• Air conditioning: Packard developed a working air conditioning system for its 1940 model.
• Cruise control: Ralph Teetor invented cruise control in 1948. However, its first commercial application appeared in the 1958 Chrysler Imperial.
• Car keys: Chrysler introduced the modern car key to start the electric starter and ignition system in 1949.
• Power steering: Back in 1951, Chrysler Imperial became the first to offer power steering in commercial vehicles.
• Seat belts: Nils Bohlin developed the modern three-point seat belt at Volvo in 1959.
• ABS technology: Mercedes-Benz introduced ABS for automobiles in 1978.

Frequently Asked Questions

The following are common questions and answers about the early days of automotive technology.

Why did steam-powered cars disappear?

Steam-powered cars couldn’t compete with the rapid development of internal combustion engines. They took a long time to start, needed constant water stops and were much more complicated to operate.

Why were early cars mostly owned by wealthy people?

The main reason is high production costs. Before the moving assembly line, cars were mostly hand-assembled. They were also difficult to maintain because fuel and specialized parts were expensive.

If electric cars were popular, why did gasoline cars take over?

Gasoline cars had a much longer range and were cheaper thanks to mass production, while electric cars had a limited range and were much slower. The abundance of gasoline and the high cost of batteries also contributed to electric cars’ initial decline in popularity.

Were roads designed for automobiles in the beginning?

No, most early roads were built for horses and carriages. Governments began paving roads as car ownership increased.

Driven by Innovation

Automotive technology has improved rapidly. Cars moved from purely mechanical machines into vehicles powered by electronics, software and advanced computing systems. The early innovations helped them become what they are today.
