5 Automotive Innovations That Changed the World Beyond Cars

The world of automotive is fast and advanced. It all began in the 17th century with carriages, then steam-powered vehicles capable of human transportation in the 18th century, and the beginning of internal combustion engines in the 19th century.

Since then, the automotive industry has progressed significantly, with about 1.5 billion cars running on the road today globally.

This mass adoption is driven by innovations in automotive technology. Some of the key advancements leading the sector in recent times include electrification, autonomous driving, new manufacturing processes, and sustainability with an aim to enhance efficiency, safety, and user experience.

Interestingly, innovations transforming the sector aren’t limited to just the automotive industry but are also driving change outside of it. With about a million patents being filed and granted in the automotive space, the effect of technological advancements has been pretty far and wide. 

Over the years, many disruptive technologies have been developed for the industry, which is the hotbed of innovation. Now let’s take a look at some of the most prominent tech advances that have crossed over into other fields.

So, here are the most notable automotive technological innovations and how they have changed the world we live in.

Automotive Aerodynamics Innovations

In order to build better cars, we need to understand just how cars move through the air. This means taking a deep dive into aerodynamics, which is the study of the motion of air when affected by a solid object.

The earliest designs of cars were essentially boxes on wheels, as little thought was given to aerodynamics, but then increased competition and more powerful engines led to more efficient designs through automotive aerodynamics.

As engineers began to experiment with various shapes and sizes, they realized that certain factors like wind resistance and fuel efficiency were closely related to the issues of airflow and drag. By studying aerodynamics, engineers were able to reduce drag and improve fuel efficiency in vehicles. Aerodynamics also helps minimize noise emissions and prevents undesired lift forces.

Notably, in the early 20th century, Hungarian aeronautical engineer Paul Jaray started designing an ultra-aerodynamic car with a teardrop-shaped body to minimize wind resistance and maximize fuel efficiency. He also provided input on the groundbreaking exterior design of the Tatra T77, one of the first serial-produced, truly aerodynamically designed automobiles.

So, it was the result of decades of aerodynamic improvements that have provided us with today’s automobiles, which use sensors and actuators to adjust the shape as well as the configuration of a vehicle’s body in response to changing driving conditions.

Understanding aerodynamics also influenced the design of wings, spoilers, streamlining, flat floors, air curtains, wheel covers, and many other components. Interestingly, all these advancements initially started with high-end cars and then trickled down to consumers, becoming common in everyday vehicles.

Over time, the automobile industry’s comprehension and implementation of aerodynamics have dramatically improved fuel efficiency for vehicles, making modern transportation more energy-efficient and safer. It also influenced the shape of trains, aircraft, robotics, wind turbines, and even architecture.

Now, if we look at one of the most aerodynamic cars ever made, Tesla (TSLA +1.14%) is among the top. 

The electric car maker has been setting standards for EV performance and range, in part thanks to its low drag design. The Tesla Model 3 boasts an ultra-low 0.23Cd drag coefficient, while the Model S’s drag figure is 0.208Cd, with the latest models having an even more improved drag coefficient. 

Elon Musk’s Tesla is a trillion-dollar market cap company, whose shares, as of writing, are trading at about $320, down nearly 20% YTD. It has an EPS (TTM) of 1.82 and a P/E (TTM) of 178.12.

In the first quarter of 2025, the company produced over 362,000 EVs and delivered over 336,000 vehicles. For this period, its revenue was $19.34 billion, including $595 million in revenue from credits. Net income was $409 million and operating income was $400 million, while earnings per share were 27 cents adjusted.

Anti-lock Braking System (ABS)

Automation is making its way into all spheres of our lives, and that includes our automobiles. While today’s cars boast a high level of automation, starting to demonstrate the power to operate and make decisions without any human intervention, one of the earliest and most fundamental electronic safety automation systems introduced in mass-produced cars is the anti-lock braking system (ABS).

The purpose of ABS is to assist with steering in an emergency stop by creating improved traction. The system essentially prevents the wheel from locking up during braking, thereby maintaining tractive contact with the road surface and allowing the driver to maintain more control over the vehicle and steer it to safety.

ABS utilizes the principles of threshold braking (the maximum amount of brake pressure applied just before wheels lock up) and cadence braking (repeatedly and rapidly pumping of the brake pedal to steer and slow the vehicle), which are techniques once practiced by only professional drivers before the system became widespread. It basically offers better vehicle control, even in emergencies.

The modern ABS system, which has now become the standard, was invented in 1971 by Mario Palazzetti at the Fiat Research Center. It was called Antiskid before its patent was sold to Bosch, who then renamed it ABS. The German tech company actually patented the concept of preventing wheel locks a few decades before that. Early implementation of the system was seen on premium vehicles like Cadillacs.

Over time, ABS has become more effective and sophisticated. Its integration with other advanced safety systems like Electronic Stability Control (ESC) and Traction Control System (TCS) further enhances vehicle safety. This safety anti-skid braking system is also used on buses, trucks, motorcycles, bicycles, and aircraft.

One of the major players in this field is Aptiv (APTV +4.32%), a technology company that develops and manufactures advanced safety systems for vehicles. It also produces components and software for ABS. With a market cap of $15 billion, APTV shares are currently trading at $70.70, up 13.72% YTD. With that, it has an EPS (TTM) of 6.03 and a P/E (TTM) of 11.40.

For Q1 2025, the company reported GAAP revenue of $4.8 billion, a GAAP net loss of $11 million, GAAP operating income of $448 million, and adjusted EBITDA of $758 million. The GAAP diluted loss per share was $0.05, and the diluted earnings per share were $1.69. The company generated $273 million of cash from operations. Aptiv also reported having $2.52 billion available for future share repurchases.

How ECUs Revolutionized Vehicles

Originally synchronizing car engines and safety functions, the ECU has become the backbone of automation, robotics, and electromechanical engineering.

Serving as the ‘brains’ of modern automobiles, Electronic Control Unit (ECU) or Electronic Control Module (ECM), have enabled the concept of “smart” embedded systems. These sophisticated mini-computers allow for innovations in connectivity, efficiency, and safety. 

It was over half a century ago that the concept of using electronic control in vehicles first emerged. At the time, ECUs were pretty simple devices, only used for specific functions. Over time, their usage expanded beyond ignition timing to include fuel injection and emission control, as well as managing safety systems such as airbags and stability control, and later for infotainment and connectivity.

What these units do is they collect data from numerous sensors that are placed throughout a vehicle, which allows them to make real-time decisions. The data is then processed using algorithms, and finally, commands are sent to actuators (components that convert electrical or electronic commands into actions or mechanical work) to optimize performance and provide advanced features. 

In today’s vehicles, ECUs have become a critical element that allows companies to manage and enhance their various functions. They are actually responsible for the overall performance of vehicles, and for this, they monitor a wide range of parameters, including stability, braking, emissions, and engine performance. 

Notably, ECUs are necessary for the development of autonomous vehicles by enabling advanced driver assistance systems (ADAS). Moreover, they facilitate communication between various vehicle components, which allows for seamless integration and improved reliability.

Paving the way for vehicle-to-vehicle communication, the enhanced connectivity through an advanced and growing number of ECUs in modern vehicles, however, also means managing the increasing complexity, and cybersecurity has become challenging and extremely important. 

These units are currently inspiring “smart” embedded systems in robotics, industrial automation, and medical devices.

Driven by advancements in EVs, autonomous driving, and connectivity, the ECU industry is gaining a lot of traction with the likes of Bosch, Continental, Denso, and ZF dominating the market with cutting-edge technologies.

The Netherlands-based NXP Semiconductors NV (NXPI +1.88%) is a major supplier of components for ECUs. Its product solutions are used in a range of applications, including automotive and computing, wireless and wireline infrastructure, mobile communications, and the Internet of Things (IoT).

Carbon Fiber in Cars and Beyond

The resource-intensive automobile manufacturing requires a substantial amount of raw materials that are sourced from all over the world. What automobiles need are materials that are lightweight and durable, so that our vehicles are not only fast and efficient but also long-lasting.

This means steel, plastic, aluminum, rubber, glass, fiberglass, lead, copper, magnesium, and titanium are the most used materials in auto manufacturing.

There is yet another more complex material that’s seeing a lot of usage, and that’s carbon, a lightweight, rigid material offering a unique look. In making vehicles, it’s mostly carbon fiber reinforced polymer (CFRP) that is utilized. 

It’s a composite material that combines two or more components, as such performing better than unique materials. Carbon fiber composite has been recognized as a pioneer in the automobile industry thanks to its low weight, less fuel consumption, design flexibility, corrosion resistance, and improved safety.

It was in 1979 that McLaren replaced aluminum, the go-to material of the time, with carbon fiber. This made the McLaren MP4/1 the first car to make use of carbon composite and made its debut in the Argentine GP, showcasing the world its lightness and crash safety.

With this move, the luxury automobile manufacturer completely changed the racing game. While the F1 teams started catching up, the technology then made its way onto the street and into luxury and sports cars.

Though not commonplace in everyday cars due to the high cost and complex manufacturing processes of carbon, carbon fibers can be found in models like the BMW 7 Series, Audi R8, Rolls-Royce Phantom, and some variations of Ford (F +4.19%) Mustangs. Mercedes, meanwhile, is planning to debut sustainable carbon fibre composites in its 2025 Formula 1 car, the W16. Carbon fiber will make up 75% of the car’s materials in the company’s attempt to achieve Net Zero by 2040.

Besides high-end cars, the composite is also used in bicycles, aircraft, wind turbine blades, and sporting equipment like tennis rackets and golf clubs.

The $4.5 billion market cap Hexcel (HXL +1.45%) is a prominent name in the sector with its product range covering carbon fiber as well as other fiber-reinforced materials, resins, honeycomb, and composite structures for application across automotive, space and defense, aerospace, and other industries.

GPS Navigation’s Automotive Origins

The Global Positioning System, or GPS, is a powerful technology allowing us to make our way from one place to another with ease. It allows us to share our locations with friends and families, achieve better time management, enable quick emergency responses, and have peace of mind.

For businesses, this technology has further allowed for increased efficiency, improved route planning, enhanced productivity, lowered costs, better management, real-time visibility, and stronger security.

Offering tons of benefits to people and businesses alike, GPS has been a powerful technological advancement of our era. Its origins actually date back to the Cold War, when it was developed by the military for highly precise location and timing.

The wireless-based navigation system first emerged in 1961, when it was primarily limited to military use. A few years later, General Motors Research (GMR) began developing a navigation system called DAIR (Driver Aid, Information & Routing), which wasn’t based on satellite technology and was neither practical nor scalable.

In the 1980s, Japanese companies Honda (HMC +1.89%), Toyota (TM +0.35%), and Nissan used dead reckoning technology for their automobile navigation systems, with Honda’s Electro Gyrocator becoming the first car navigation system to be made available commercially.

While Toyota introduced a CD-ROM-based navigation system on its Toyota Crown, the Mazda Eunos Cosmo was the first one with a built-in GPS navigation system. In the 1990s, Toyota further advanced the GPS capabilities in its cars, with others following suit.

While the military was the original purpose behind the development of GPS, the transportation sector helped it gain widespread adoption. In vehicles, GPS not only offers real-time route guidance and enhanced travel efficiency but also provides adaptive cruise control and collision avoidance, in turn, improving both convenience and road safety. 

Today, hardly any vehicle doesn’t use GPS tracking, whether it is vans, trucks, school and public transport buses, or trains; there are rarely any exceptions to this.

The core of GPS technology is a network of satellites, each continuously transmitting signals that are received by devices such as smartphones and navigation systems.

So, advances in satellite engineering, as well as display, batteries, and computing, helped the technology mature into an operational system that all could use. An extensive and growing network of satellites has made GPS a vital part of our lives, with applications ranging from global logistics and agriculture to wildlife tracking, disaster relief, fitness trackers, wearables, smartphones, and more.

In the navigation realm, Qualcomm (QCOM +1.66%) supplies GPS chipsets for mobile devices and automobiles. It also develops integrated circuits and system software, including automated driving, advanced driver assistance, digital cockpit, RF front-end, and Internet of Things.

With a market cap of $173 bln, QCOM shares are trading at $159.5, up about 4% YTD. It has an EPS (TTM) of 9.79 and a P/E (TTM) of 16.28 while the dividend yield offered is 2.23%. For Q2 2025, Qualcomm reported GAAP revenue of $11.0 billion, with combined automotive and IoT revenues growing 38% YoY. As for GAAP EPS, it was $2.5,2, and non-GAAP EPS was $2.85.

So, these are some of the groundbreaking innovations from the automotive sector that have been driving transformation in many other fields.
