## Pioneers

### Cugnot steam carriage (1769–1771)

French military engineer Nicolas-Joseph Cugnot built a three-wheeled steam-powered "fardier" to haul artillery. It is widely regarded as the first full-scale self-propelled mechanical vehicle.

Topics: Powertrain, Design, steam, military

Further reading: [Read more](https://en.wikipedia.org/wiki/Fardier_%C3%A0_vapeur)

- Cugnot demonstrated a steam tractor in 1769, commissioned by the French Army to tow heavy cannon.
- Its single front wheel carried both the boiler and the two-cylinder engine, making it heavy and hard to steer.
- The fardier crawled at only a few kilometres per hour and had to stop frequently to rebuild steam pressure.
- The 1770–71 vehicle survives and is displayed at the Musée des Arts et Métiers in Paris.

Later built on by: Trevithick road locomotives
Later challenged by: Système Panhard

### Trevithick road locomotives (1801–1803)

Cornish engineer Richard Trevithick applied compact high-pressure steam engines to road vehicles. His Puffing Devil and London Steam Carriage showed passenger steam travel was possible.

Topics: Powertrain, steam, high pressure

Further reading: [Read more](https://en.wikipedia.org/wiki/Puffing_Devil)

- On Christmas Eve 1801 the Puffing Devil carried several passengers up Camborne Hill in Cornwall.
- Trevithick used high-pressure steam rather than Watt-style low pressure, making the engine small enough for a road vehicle.
- His 1803 London Steam Carriage ran on city streets but found no investors and was dismantled.

Builds on: Cugnot steam carriage
Later built on by: Stanley Steamer, Red Flag Act

### Lenoir gas engine (1860–1863)

Belgian-French engineer Étienne Lenoir built the first commercially successful internal combustion engine, burning coal gas. He later fitted one to a cart, the Hippomobile.

Topics: Powertrain, internal combustion

Further reading: [Read more](https://en.wikipedia.org/wiki/%C3%89tienne_Lenoir)

- Lenoir patented a double-acting coal-gas engine in 1860; several hundred were sold to power workshops.
- With no compression stroke, the engine was very inefficient, turning only a few percent of its fuel into work.
- Around 1863 his Hippomobile made a slow trip from Paris to Joinville-le-Pont and back.

Later built on by: Otto four-stroke engine, Benz Patent-Motorwagen
Later challenged by: Otto four-stroke engine

### Red Flag Act (1865–1896)

Britain's Locomotive Act 1865 imposed strict speed limits on mechanical road vehicles and required a person to walk ahead of them. It is often blamed for slowing early British motoring.

Topics: Regulation, UK law, speed limit

Further reading: [Read more](https://en.wikipedia.org/wiki/Locomotive_Acts)

- The 1865 Act capped road locomotives at 4 mph in the country and 2 mph in towns.

Topics: Powertrain, Manufacturing, four-stroke, Deutz

Further reading: [Read more](https://en.wikipedia.org/wiki/Nicolaus_Otto)

- Otto’s 1876 engine compressed its fuel–air charge before ignition: intake, compression, power and exhaust.

Topics: Racing, competition, France

Further reading: [Read more](https://en.wikipedia.org/wiki/Paris%E2%80%93Rouen_(motor_competition))

- In July 1894 dozens of entrants set off on the 126 km run from Paris to Rouen, judged on safety and ease of handling.
- A de Dion steam tractor arrived first but was denied top prize because it needed a stoker; petrol cars shared the award.

Challenges: Paris–Rouen & early races
Later built on by: Electric self-starter

### First electric cars (1899–1914)

Around 1900 battery-electric cars were quiet, clean and easy to start, and held a large share of the American market. Limited range and the arrival of cheap petrol cars pushed them into decline.

Topics: Electric, Powertrain, battery, hybrid

Further reading: [Read more](https://en.wikipedia.org/wiki/History_of_the_electric_vehicle)

### Electric self-starter (1911–1912)

Charles Kettering of Delco developed a practical electric starter, introduced on the 1912 Cadillac. It removed the dangerous hand crank and one of the main advantages of electric cars.

Topics: Powertrain, Safety, Kettering, Cadillac

Further reading: [Read more](https://en.wikipedia.org/wiki/Charles_F._Kettering)

- Hand-cranking engines was strenuous and could break arms when the engine kicked back.

### Moving assembly line (1913–1914)

At Highland Park, Michigan, Ford introduced a moving assembly line for complete Model T chassis. Paired with the $5 day, it defined twentieth-century mass production.

Topics: Manufacturing, Business, Highland Park, Fordism

Further reading: [Read more](https://en.wikipedia.org/wiki/Assembly_line)

- In 1913 Ford began pulling chassis past stationary workers, inspired partly by meatpacking disassembly lines.
- Chassis assembly time fell from about 12.5 hours to roughly 1.5 hours.
- In January 1914 Ford doubled pay to $5 a day to cut turnover from the monotonous line work.
- The system depended on precisely interchangeable parts so that no hand fitting was needed.

## Mass Production

### Leaded petrol (1921–2021)

In 1921 GM researchers under Charles Kettering found that tetraethyl lead stopped engine knock, allowing higher compression. Leaded petrol spread worldwide before its health toll forced a century-long phase-out.

Topics: Powertrain, Regulation, tetraethyl lead, antiknock

Further reading: [Read more](https://en.wikipedia.org/wiki/Tetraethyllead)

- Thomas Midgley found tetraethyl lead’s antiknock effect at GM in December 1921.

Topics: Design, Business, Harley Earl, styling

Further reading: [Read more](https://en.wikipedia.org/wiki/Harley_Earl)

- Earl’s first project, the 1927 LaSalle, was styled as a complete, harmonious design rather than engineered piecemeal.

### Clean Air Act & catalytic converter (1966–1975)

California’s smog problem drove the first tailpipe standards, and the US Clean Air Act of 1970 required drastic cuts in car emissions. Catalytic converters, needing unleaded fuel, arrived on 1975 models.

Topics: Regulation, Powertrain, emissions, EPA, CARB

Further reading: [Read more](https://en.wikipedia.org/wiki/Clean_Air_Act_(United_States))
