An Overview of Automotive Software Today

The automotive software industry isn't just experiencing mild growth – it's rapidly expanding. The $18.1 billion industry is estimated to grow to $134.94 billion in just ten years (MarketResearch.com).

The increasing popularity of software-defined vehicles (SDVs), advanced driver assistance systems (ADAS), and vehicle connectivity (software features like navigation, infotainment, and remote diagnostics) is driving the growth of this digital transformation.

The Transformation of the Automotive Software Market

Traditionally, cars were built around mechanical components, with electronics and software added later in production, often in limited quantities. If there was software on a vehicle, it was typically function-based and required updates at a dealership.

Today, cars have shifted to software-first engineering. Vehicles update their software automatically over-the-air (OTA), and cars continue to evolve even after being sold. Automotive software now reaches far beyond basic diagnostics and functions, offering a suite of experience-enhancing features.

Rather than partnering with outside tech developers, many car manufacturers have invested in in-house software stacks. This shift marks a new battleground for automakers to compete in, providing a unique, branded user experience.

Leading the market, APAC (Asia-Pacific Region) is currently the most active hub for automotive software engineering. While they may not have the most volume, the U.S. leads in growth as the fastest-growing automotive software market.

The Rise in Code Volume

In the nineties, cars had tens of thousands of lines of code. This increased to around 100 million in luxury cars by the 2010s. Today, advanced vehicles can have over 300-400 million lines of code.

This explosive growth reflects a broader transformation: the auto industry is no longer just about engineering machines, but about engineering software-driven experiences.

These four key drivers have fueled the transformation of vehicles into software-first engineered machines:

1. Electrification: Software-Driven Systems

Electric Vehicle (EV) sales have increased yearly as consumer demand grows, technology improves, and governments enforce stronger incentives and regulations. This means that software development for the automotive industry is also growing.

EVs rely on software to manage their internal systems. Many hardware-driven systems and mechanical components have been replaced by software. Everything, from ignition and brakes to temperature controls and seat adjustments, is now controlled by software.

2. Autonomous Vehicles: Driving Intelligence Through Code

Developing self-driving features requires billions of lines of code, artificial intelligence and machine learning models, and high-performance compute platforms.

Nearly every new car comes equipped with ADAS features, such as Forward Collision Warning, Automatic Emergency Braking, and Lane Departure Warning. These features are all powered by software applications, playing a major role in modern vehicle safety and functionality.

3. Vehicle Connectivity: Cloud Services & Updates

Whereas older vehicles with software required in-person updates at the dealership, new vehicles are connected to the cloud, enabling over-the–air (OTA) updates, and requiring their own cybersecurity and cloud integration.

This has expanded the scope of automotive software from internal functions to advanced connectivity features, requiring specialized software engineering for communication, data management, and cloud integration.

4. Digitalization: Software-Defined Experiences

Vehicle features are becoming increasingly like smart devices with software-defined experiences. Everything from infotainment platforms, Human-Machine Interfaces (HMIs), and personalized profiles builds a unique user experience – and this is only the beginning.

Together, these developments are transforming how cars are designed and increasing the demand for automotive software development services.

What Software is Used in the Automotive Industry?

Nearly every function of a new car is powered by software. From user interface (UI) elements to steering controls, these are the main categories of automotive software today:

1. Embedded Systems

This is software embedded directly into the vehicle's hardware for essential engine controls. These control operational functions, such as:

From core functionality to advanced intelligence, these six types of software control the customizable driving experience and provide opportunities for forward-thinkers to bring new ideas to life. Whether you're building the next in-car app, diagnostic tool, or autonomous driving feature, finding the right development partner is key to making your vision a reality.

Types of Automotive Software Development

Behind every feature in a new car is a complex network of code and development. Each system requires a different approach to development, so here's a closer look at the most common types of software development for automotives.

Embedded Software Development

Embedded software literally keeps the engine running in a new vehicle. Embedded software controls all the essential internal systems, from engine management to brake control.

Embedded software developers often use platforms like QNX or AUTOSAR to write low-level code to interact directly with the hardware.

Without embedded systems, the vehicle doesn't function. It sets the framework upon which everything else is built.

Application Software

Application software includes the programs that drivers and passengers interact with most directly. Infotainment systems, mobile apps, digital dashboards, voice assistants, and everything else that goes into the UI define the user experience.

Developers here often work with platforms like Android Automotive or custom HMI frameworks to build intuitive, branded user experiences.

Cloud-Based Automotive Solutions

Cloud solutions connect modern vehicles to several features remotely. OTA updates, remote diagnostics, and real-time traffic data are just some of the applications using cloud connectivity. It also integrates with mobile apps and external services, allowing vehicles to continue to evolve and become more personalized post-purchase.

AI + Machine Learning for Autonomous Driving

Autonomous driving features require systems that interpret and respond to real-world stimuli in milliseconds. That's where AI and machine learning come in.

Developers in this space help "train" the vehicle to recognize objects and make decisions. This type of software offers a lot of storage space.

Cybersecurity and Compliance Software

With increasingly connected vehicles, regulatory standards are in place to keep cars and their passengers safe.

Cybersecurity developers focus on protecting cars from hacks, data breaches, or software vulnerabilities. This also includes meeting global standards like ISO/SAE and UNECE WP.29.
