If the latest statistics are to be believed there are now 1.5 billion cars in the world. In fact, we've come a long way since the very first prototypes rolled off the production line. Here's a little history of the humble car for you to get you up to speed.
The history of the motor car can be traced back to the late 19th century, when Karl Benz built the first practical automobile powered by an internal combustion engine. The early motor cars were luxurious by the day's standards . . . and they were also highly expensive. In fact, only the wealthiest people could afford their own vehicle.
Of course, over the years, advancements in technology have led to the mass production of cars, making them more accessible to the general public.
The evolution of the combustion engine
The very first engines were typically two-stroke systems, with little power by today's standards. Over time, these were replaced by four-stroke engines which, in turn, gave way to fuel injection systems. Additional performance innovations since then have included turbocharging and supercharging to enhance both power output and energy efficiency. It's worth noting that the switch from carburetted engines to fuel-injected engines also reduced emissions.
Car design over time
Exterior design has also seen some major changes over the last century. Cars have become sleeker, more aerodynamic, and aesthetically pleasing. The integration of new materials such as lightweight metals, fibreglass, and composites have led to lighter and more fuel-efficient vehicles.
Importantly, this shedding of weight has not compromised safety. In fact, vehicles are safer than ever thanks to the careful design of crumple zones and passenger protection systems. The adoption of futuristic designs, such as the introduction of the streamlined "teardrop" shape in the 1930s, changed the look of cars forever.
Driving improvements
Advancements in technology for driving aids and interior comfort have been significant. The introduction of power steering, automatic transmissions, and anti-lock brakes improved the driving experience, making it easier and safer for drivers. The addition of climate control systems, navigation systems, and infotainment systems transformed the interior of cars into a comfortable and connected environment.
Safety improvements: the seatbelt and beyond
Seatbelts and airbags are two of the most important safety features available in modern cars. Their introduction and widespread adoption has greatly reduced the number of serious injuries and fatalities in car accidents - even though the number of people on the roads has increased exponentially over the last 75 years.
The seatbelt and airbags work together to prevent drivers and passengers from being thrown from the vehicle in a crash, and to absorb the impact of the collision to reduce the risk of injury.
The seatbelt was first patented in the 1950s and quickly became standard in all new cars. The seatbelt is designed to hold the driver or passenger in place during a collision, preventing them from being thrown from the vehicle. This dramatically reduces the likelihood of fatality in the event of a high-speed collision.
Airbags are a more recent safety feature - having been introduced in the late 1980s. Airbags are designed to protect the driver and passengers in a collision by inflating quickly to absorb the impact of the collision. Airbags are placed throughout the car, including the steering wheel and front and side panels, to provide maximum protection in a crash. They are triggered by sensors in the car that detect an impact and can be inflated in a fraction of a second.
According to the National Highway Traffic Safety Administration (NHTSA), seatbelts are estimated to have saved over 14,000 lives in 2018 alone. Similarly, the NHTSA reports that airbags have saved over 50,000 lives since their introduction in the late 1980s.
In addition to reducing the number of serious injuries and fatalities, seatbelts and airbags have also helped to reduce the cost of car accidents. When drivers and passengers are protected in a collision, they are less likely to suffer serious injuries, which can reduce the cost of medical expenses and lost wages.
Lowering car emissions
In recent years, the focus has shifted towards making cars more environmentally friendly. This has resulted in an explosion in the popularity of hybrid and electric vehicles. These cars use rechargeable batteries to power an electric motor and reduce the reliance on fossil fuels, reducing emissions and improving fuel efficiency.
Overall, the history of the motor car has been marked by significant advancements in technology, leading to cars that are safer, more comfortable, and more environmentally friendly. But if there was one vehicle that really changed it all, it would be the Model T Ford...
The first mass production car: Model T Ford
The Model T Ford was introduced by the Ford Motor Company in 1908 and quickly became one of the most popular vehicles in America. The impact of the Model T on society was profound and far-reaching, as it transformed the way people lived, worked, and travelled.
What set the Model T apart from all cars that had gone before it was its affordability. It was targeted at the average person and was mass produced so that thousands of people could experience the joy of driving a family car.
The Model T also had a major impact on the economy. The assembly line method of production that was used to build the Model T became a model for other industries. This spurred the growth of the American industrial economy, creating jobs and bringing wealth to people in the USA.
The Model T also had a significant impact on the environment. Cars were no longer just a luxury item, but an essential part of everyday life. People could travel faster and farther than ever before, which allowed for greater economic and social mobility. However, the increased use of cars also led to increased pollution, as well as the creation of new roads, bridges and highways.
