Automobile Timeline, 1769–2040: From Steam to Electric Cars

The first vehicle to move under its own power ran on steam

Cugnot built a three-wheeled steam vehicle to haul cannon for the French army — generally counted as the first self-propelled road vehicle. But the heavy boiler sat over the single front wheel, making it hard to steer, and it ran out of steam after roughly a quarter of an hour. The gap between "moves under its own power" and "is actually useful" was already wide.

• Speed Slower than walking
• Run time ~15 min before steam ran out

People and institutions: Nicolas-Joseph Cugnot

NotePer the Linda Hall Library account. Sources differ on whether to date the machine to 1769 or to the second 1770 vehicle.

The four-stroke engine — still how most cars work

Otto made a working engine that cycles through four steps: draw in the mixture, compress it, burn it, push the exhaust out. Compressing before burning is the key move, and it raised both power and efficiency sharply. A century and a half later, most engines on the road still repeat those same four steps.

The Benz Patent Motor Car — the date usually called the car's birthday

Carl Benz filed a patent (no. 37435) for a three-wheeler designed around its petrol engine rather than adapted from a carriage. That integration is what separates it from earlier attempts. In 1888 his wife Bertha drove it over 100 km with their two sons, without telling him, and demonstrated in public that the thing actually worked.

The first car past 100 km/h was electric

Jenatzy's torpedo-shaped electric car La Jamais Contente recorded 105.882 km/h, making it the first road vehicle to break 100 km/h. At that moment electricity was the fastest way to move a car. At the close of the 19th century steam, electricity and petrol were still running neck and neck, and the outcome was open.

• Record 105.882 km/h
• Power Two 25 kW motors

People and institutions: Camille Jenatzy

NoteSources differ between 29 April and 1 May 1899 for the record date; the figure of 105.882 km/h is consistent across them.

The hybrid already existed in 1900

A 24-year-old Ferdinand Porsche built an electric car with motors inside the wheel hubs, then added a petrol engine driving a generator to feed them — the Semper Vivus. That is the same idea as today's series hybrids and in-wheel motors. The batteries and generators of the time were far too heavy for it to be produced in any quantity.

The electric starter takes away the electric car's last advantage (unverified)

Petrol cars had to be hand-cranked to start — heavy work, and dangerous. Avoiding that was one reason buyers chose electric cars. An electric self-starter erased the difference, which means battery technology was, ironically, used to help the petrol car win. The date and details still need checking against a primary source.

The moving assembly line — build time falls to an eighth

At Highland Park, the chassis started moving past workers who each stayed put and repeated one task. Assembly went from 12.5 hours per car to 93 minutes. This is the substance behind the falling price. The same logic is what gets invoked today when anyone talks about driving down the cost of building an EV.

• Assembly time 12.5 hours → 93 minutes

The gas turbine car — it ran, but the fuel consumption was hopeless

Rover put an aircraft-style gas turbine into a road car, JET1. Turbines are light, smooth and not fussy about fuel. But they respond slowly to changes in demand, and above all they drank fuel at a rate nothing could excuse. Chrysler reached the same conclusion in the 1960s and walked away. Building a car that runs and building one you can use daily are different problems.

The first fuel cell car was never allowed on public roads

GM built the Electrovan around a Union Carbide fuel cell — 127 years after Grove's discovery. The hardware was so bulky that a six-seat van became a two-seater, and the platinum in the cells alone cost more than a fleet of ordinary vans. It was never tested on public roads because of the pressurised hydrogen and oxygen, and an external tank did explode during testing. The principle was right; the materials and the safety case were not there yet.

• Range ~150 miles (estimated)
• 0–60 mph 30 seconds
• Seats 6 → 2

A law written around technology that did not exist yet

The US Clean Air Act amendments required new cars to cut emissions by 90% by 1975. No one had a settled way to do that at the time. Rather than regulating what existed, the deadline was set first to force the technology out — an approach later called technology-forcing. The deadline is what pushed the catalytic converter into production.

Leaded petrol is banned outright — 75 years after it was introduced

From 1 January 1996 lead could no longer be added to petrol in the US, about 75 years after it went in to stop knock. Retiring something that genuinely worked took three things in sequence: measurement (Patterson), regulation (1970), and a replacement technology (catalysts and unleaded fuel). That elapsed time is a useful reference point when thinking about today's emissions rules.

An engine that burns hydrogen — neither battery nor fuel cell

Toyota entered endurance racing with a car whose internal combustion engine runs on hydrogen. A fuel cell generates electricity from hydrogen; this simply burns it. The appeal is that existing engine parts and factories carry over, and the noise and vibration survive. But high combustion temperatures still produce nitrogen oxides, and efficiency trails a fuel cell. It is a good illustration that the field has not converged on one answer.

The EU withdraws its 2035 combustion engine ban

On 16 December 2025 the European Commission dropped the 2023 rule requiring all new cars to be zero-emission from 2035, replacing it with a 90% reduction target. The remaining 10% can be offset with EU-made low-carbon steel or with e-fuels and biofuels, and plug-in hybrids and combustion cars may continue. This is a Commission proposal, not settled law — it still has to go through the Parliament and the Council. The pace of the changeover is being set on the political side, not the technical one.

People and institutions: European Commission

NotePer Euronews. This is a European Commission proposal; it is not settled until negotiated with the Parliament and Council, with talks reported to start in January 2026.
