Early Automobile Engines: From One Cylinder to the First V8 | Stirlingkit

The first car engines had one cylinder and less than one horsepower. Within about thirty years they had grown into four-cylinder engines as standard — and the first mass-produced V8 was on the road by 1914.

If you build or run model engines, you have probably wondered where the layouts on your bench came from. Why one cylinder, then two, then four in a row? Why did the engine move to the front of the car? And when did the V8 arrive? This guide walks through those thirty years step by step, in plain terms, and explains what collectors mean when they call a car a "veteran."

01One cylinder: the first car engines (1885–1886)

The automobile started with two very different single-cylinder engines, built in the same corner of south-west Germany in the same year.

Carl Benz: slow, horizontal, built into the car

Carl Benz laid his engine flat at the back of the Patent-Motorwagen, with a large horizontal flywheel. It produced about 0.75 hp and turned slowly. Benz used electric spark ignition, and he designed the engine and the vehicle together as one machine — which is why his 1886 patent is called the birth certificate of the automobile.

Gottlieb Daimler and Wilhelm Maybach: small, upright, fast

In 1885 Daimler and Maybach patented a compact upright single-cylinder engine nicknamed the "grandfather clock" for its shape. It displaced 264 cc and made about 0.5 hp at 600 rpm — fast for the time. Instead of an electric spark it used hot-tube ignition: a small tube kept glowing by an outside flame lit the mixture inside the cylinder.

Two ideas, then: a slow engine designed around one vehicle, and a fast, light engine that could power almost anything. Over the next twenty years, the fast and light idea won.

Why one cylinder is rough: a four-stroke single fires only once every two turns of the crankshaft. Between those power strokes, the heavy flywheel keeps everything turning. That is why early engines had such large flywheels — and why they shook.

02Two cylinders: more power, less shaking (1889)

The obvious way to get more power and smoother running was to add a second cylinder. In 1889 Daimler built a V-twin of 565 cc producing about 1.3 hp, and it was shown at the Paris Exposition that year.

Two cylinders meant twice as many power strokes for each turn of the crank. The engine ran more evenly and needed less flywheel to keep going. French companies took notice — and that is where the next big change happened.

03The engine moves to the front (1891)

Panhard et Levassor in Paris began building cars with Daimler-licensed engines in 1890. In 1891 Émile Levassor rearranged the whole car: engine at the front, then a clutch, then a gearbox, then drive to the rear wheels.

It sounds ordinary today because most cars used that order for decades afterwards. At the time it was a big step. Putting the engine at the front gave room for larger engines, better cooling and a proper gearbox — instead of the belt-and-pulley drive of the first cars.

04Small engines that spin fast (1895)

In 1895 the French firm De Dion-Bouton introduced a tiny single-cylinder engine of just 137 cc. It was designed to run at 900 rpm, usually ran at around 2,000 rpm and reached 3,500 rpm in trials — extraordinary for its day.

The lesson was simple: a small engine that turns quickly can make as much power as a big slow one, while weighing far less. De Dion-Bouton engines were licensed to more than 150 manufacturers, and about 40,000 had been supplied across Europe by 1904. Many of the cars you will see at veteran car events are powered by them.

05Four cylinders become the standard (around 1900–1910)

As cars grew heavier and faster, makers moved to four cylinders in a row. The reasons are the same ones that matter on a model engine today:

• Smoother running. A four-stroke four-cylinder fires twice for every turn of the crank, so there is always a piston pushing.
• More power without huge pistons. Four medium cylinders rev more freely than one or two very large ones.
• Easy to fit at the front. An inline engine is long and narrow, which suits the front-engine layout from 1891.

By the time the Ford Model T arrived in 1908 with a four-cylinder engine of about 20 hp, the inline-four was simply what a normal car used — and it stayed that way for most of the century.

06The first V8 engines (1902–1914)

The V8 did not start in America. French engineer Léon Levavasseur patented a V8 in 1902, and his Antoinette engines, built from 1903 to 1912, powered racing boats and early aircraft, where a lot of power from a light, compact engine mattered most.

In cars, the turning point came in 1914, when Cadillac put the first mass-produced V8 into its Type 51. Eight cylinders in two banks gave smooth power in an engine short enough to fit under a normal bonnet.

The V8 became an engine for everyone in 1932, when Ford cast a complete V8 block in one piece and sold it at an affordable price. That story is in our article on how the Ford Flathead V8 made the car affordable.

07What is a veteran car?

Most of the engines above belong to what British collectors call the veteran era. In the UK, a veteran car is one built before 1905. The term is set by the Veteran Car Club of Great Britain, and it is stricter than "vintage" or "classic," which many people use loosely.

In the United States the terms work differently. The Antique Automobile Club of America, for example, treats a car over 25 years old as an antique. So a car can be "classic" in one country and "antique" in another — but "veteran" in the British sense always means pre-1905.

The London to Brighton Veteran Car Run

The best-known veteran car event is the London to Brighton Veteran Car Run, held on the first Sunday of November. Only cars built before 1905 may take part. They leave Hyde Park around sunrise and cover about 54 miles to the coast.

The run remembers 14 November 1896, when a new law raised the speed limit for motor cars in Britain to 14 mph and motorists drove to Brighton to celebrate. It is often described as the world's longest-running motoring event.

By that definition, the 1886 Benz Patent-Motorwagen is the earliest veteran car of all — the car every other veteran descends from.

08See these engines run today

Original veteran cars are rare and expensive, and most live in museums or private collections. The mechanisms, though, are easy to study up close as working models:

• The 1886 single cylinder, running on real gasoline — the R18 three-wheeler engine model is made ready to run, with a working internal-combustion engine.
• The whole 1886 car, built by hand — the TECHING DM229 is a 430-part metal kit. Electric-powered, it moves the piston, chains and rear wheels so you can watch the original layout work.
• A single-cylinder engine of the same era — hit-and-miss engines powered farms and workshops in the same decades. The RETROL HM-01 runs on gas and fires only when it needs to, just like the full-size engines.
• Where the V8 ended up — our V8 engine model kits let you build and run a modern descendant of the 1914 layout.
