Consider your daily drive to work for a moment. You get into your car, buckle into place, and ride smoothly through traffic, with responsive brakes and protection with new safety features. These things are easy to take for granted, but the driving experience you have today is light-years ahead of what drivers in the early days knew.

The first cars that arrived on American roads were slow, temperamental, and downright hazardous. These buggy vehicles failed frequently, provided no or little protection in accidents, and were more expensive than most middle-class households could pay for. Riding wasn’t the free-road experience we have today, it was a road adventure of risk and unpredictability.

How did these early machines lead to the high-tech cars we drive today? The answer is to constant innovation. In the history of car manufacturing, great engineers and inventors never accepted the norm. They defied rules, experimented with new forms, and developed technology that would revolutionize the transportation world forever.

The progress of car technology innovations has not just made cars faster or prettier. These in-vehicle technologies have saved hundreds of thousands of lives, carried millions of individuals where they had to go, and made the ordinary act of driving safe, convenient, and enjoyable. Continue reading to look at five innovative technologies that revolutionized everything about driving.

1. Assembly Line: Mass Production Redefining Accessibility

Henry Ford was an engineer at the Edison Illuminating Company in Detroit before he revolutionized the motorcar industry. The work introduced him to the technical and analytical skills that he later applied to revolutionize the production process of cars. Through his rise to chief engineer, Ford acquired vast knowledge about mechanical systems as well as efficient means of producing things, the knowledge that would eventually prove very valuable to his innovations.

The Model T and Assembly Line Production

Ford’s greatest achievement was the Model T and his innovative use of assembly line production. Instead of having highly skilled craftsmen construct each vehicle from beginning to end—a time- and money-consuming process—Ford established a new system. Under the scheme, the men did not shift position but stayed in one location as the car passed along a conveyor system. Each man only had a single task to repeat over and over, so each vehicle could be manufactured much more quickly.

Mass Producing Vehicles for Middle-Class American Families

As a result of this innovation, Ford lowered the cost of the Model T by an enormous margin to just $825 (approximately $23,000 today). This paved the way for the first time in history for middle-class American families to be able to buy a car.

The Benefits of Assembly Line Production

But the advantages of assembly line production extended even further than just making cars less expensive to manufacture:

Uniform quality inspection: Now that the procedure has been standardized, each car made would be equal in quality.

More accuracy: With the single tasks performed by special labor, Ford ensured every part was the perfect fit when assembled.

Production in less time: What took more than 12 hours to assemble a car now takes just 93 minutes.

Interchangeable parts: This facilitated easier repair for owners because they could just swap out damaged parts rather than having to do repairs.

A Transformation in American Society

This mass production revolution wasn’t only bringing cars within reach—it was also changing American society as a whole. Suddenly, personal transportation was within the reach of the average working man and woman, who were freer and more mobile than ever before.

2. Independent Suspension Systems: Minimizing Ride Harshness

Before independent suspension systems, which transformed motoring, riders used to experience bone-rattling rides over even minor road bumps. Everything from bumps and potholes went directly through stiff axles straight into the cabin, making car riding long and exhausting.

Leyland Motors first developed shock-damping suspension technology in the 1920s in its innovative torsion-bar system. This used bent metal bars to damp road shock, a huge improvement over the primitive leaf springs that dominated the market at the time. Although this provided a better ride, the true innovation came from Italy.

The Lancia Lambda, which appeared in the mid-1920s, was the first to make use of automobile comfort technology through the use of independent suspension for all four wheels. In contrast to other systems where wheels on the same axle moved together, this revolutionary design permitted each wheel to move independently of road bumps. When one wheel encountered a bump, the other wheels remained in touch with the road.

It brought the following immediate advantages:

Less vibration throughout the car cabin

Greater driver control in cornering and emergency braking

Greater tire contact with the road for improved traction

Softer ride over bumpy surfaces

The independent suspension system not only made driving more convenient—it made driving safer. Enhanced wheel control enabled you to manage nasty road surfaces with ease, and less jarring driver fatigue from days of pummeling roads meant less distraction and quicker reaction time at the wheel.

3. Crumple Zones: Redesigning Car Safety Through Crash Attenuation

Prior to the 1950s, automobiles were constructed like tanks, impact-absorbing steel that didn’t bend. Sounds wonderful, right? The catch was that all of the impact energy was transmitted directly to you and your passengers. A genius engineer by the name of Bela Berenyi turned such thinking on its head with a revolutionary idea: what if some of your vehicle was made to crush inward in a collision?

Berenyi’s crumple zones are purposefully weak spots at the front and back of the body of your vehicle. When you’re involved in an accident, the zones buckle and fold in, absorbing the devastating impact energy before it can reach your passenger compartment. Attempt to catch a baseball with a hard board and with a soft glove—the glove deforms, distributing the impact.

Mercedes-Benz first innovated by putting crumple zones into mass-produced cars in the 1950s, establishing the bar for car safety features forever. The passenger area was still stiff and intact, with the outside body yielding to take the impact and preserve lives.

The results were self-explanatory. Survival rates for the collisions in high-speed crashes increased tremendously, and the severity of the injury plummeted. By adding fractions of a second to the time it takes for a vehicle to decelerate after a collision, crumple zones decrease the g-forces riders will experience. This apparently simple line of logic has preserved thousands of lives and is a central component of contemporary auto safety engineering.

4. Seatbelts: The Evolution of Life-Saving Restraints

While crumple zones distributed the force against your car body during crashes, designers realized that holding you back was just as important. Seatbelt innovation illustrates the power of ongoing innovation to turn a humble strap into one of the greatest life-saving technologies in automobile history.

Dr. C. Hunter Shelden got the seatbelt revolution of the 1950s started by pushing a retractable safety belt. He was a doctor, so he had special knowledge of crash trauma and knew that holding people in place could reduce trauma by a tremendous amount. It wasn’t abstract–he calculated that safe restraints could save drivers and riders from being thrown out or hitting the dashboard in crashes.

The automobile business took notice when Saab originally became a producer that made seatbelts standard features back in 1958. This was not an extra cost or a high-end feature—but rather, every Saab that came off the production floor was equipped with safety belts, a trend which would later become a ubiquitous practice.

Roger W. Griswold and Hugh DeHaven patented the three-point safety belt design you are used to that same year. This distributed the forces of a crash across your pelvis and chest—the two strongest points on your body—instead of focusing them on your abdomen like earlier lap belts.

The technology found legal support when the 1966 National Traffic and Motor Vehicle Safety Act required the installation of seatbelts in all new cars across the country. Such motor vehicle safety requirements made previously optional equipment a required protection, making seatbelts hard-wired non-option safety tech in each car rolling off factory floors.

5. Disc Brakes: Improving Stopping Power and Reliability

When you press your brake pedal, you are activating one of the most important safety features of your vehicle. The benefits of disc braking systems have pushed them as the modern standard of car technology, transforming the way cars are slowed down.

How Disc Brakes Work

Here’s how they do it: hydraulic-actuated calipers squeeze ceramic or metal brake pads onto a metal disc (or rotor) affixed to your wheel. Frictional contact gives you the stopping power you need, approaching a red light or in a panic stop. Hydraulic pressure is multiplied from your foot, providing firm and strong braking performance.

The Evolution of Braking Systems

The evolution of braking systems becomes clear when comparing disc brakes to their predecessor, drum brakes. While drum brakes remain common in smaller vehicles and rear axles due to their lower manufacturing costs, they can’t match the performance characteristics of disc brakes. Drum brakes enclose the braking components inside a cylindrical housing, which traps heat and can lead to “brake fade” during repeated or heavy braking.

Advantages of Disc Brakes

Disc brakes cure this issue of heat dissipation with better dissipation. With an open rotor, there’s space to provide free airflow over the braking surface to cool it quickly and provide even stopping power regardless of the situation. This dependability is something that translates directly to your well-being, you can rely on your brakes to get you out of trouble when you need them to in tricky situations, when cruising up hill roads, or hard-braking in rush hour.
