Every automaker wants modern vehicle software. Few want to throw away twenty years of engineering investment to get it. That tension sits at the center of many automotive technology programs today.
A manufacturer wants over-the-air updates. Existing architectures were never designed for them. A team wants to launch connected services. The software stack underneath was built long before anyone talked about vehicle ecosystems.
A company wants faster feature deployment. Meanwhile, dozens of ECUs, supplier dependencies, validation requirements, and active vehicle programs continue operating exactly as they did before.
This is why platform modernization has become one of the industry’s most difficult engineering challenges. Building something new is hard. Building something new without disrupting what already works is often harder.
The firms below are among those helping OEMs modernize vehicle platforms while balancing innovation, compatibility, and long-term maintainability.
Why OEMs Can’t Modernize Like Technology Companies
When a software company wants to modernize its infrastructure, it can often move relatively quickly. A vehicle manufacturer operates under a different set of constraints.
Production cycles span years. Validation requirements are extensive. Software interacts with hardware that cannot be replaced through a simple update. Supplier ecosystems involve dozens of stakeholders working across interconnected systems.
As a result, automotive modernization rarely looks like a complete replacement project. More often, it resembles controlled evolution.
New software layers are introduced gradually. Cloud platforms are added alongside existing infrastructure. Connectivity capabilities expand while older systems continue operating in parallel.
That process may not generate headlines, but it is how much of the industry is transforming today.
What Usually Gets Modernized First?
Most OEMs do not begin with a full architectural redesign. Instead, they target areas where existing systems create the biggest limitations.
Common priorities include:
- Connected vehicle platforms
- Telematics infrastructure
- Vehicle data ecosystems
- OTA update capabilities
- Digital cockpit environments
- Cloud integration layers
- Validation and testing platforms
Many software-defined vehicle programs actually begin with projects like these.
1. Avenga
One of the biggest modernization mistakes is treating every legacy system as technical debt. In reality, many existing systems continue performing exactly as intended. The challenge is extending their capabilities without introducing unnecessary complexity or risk.
That requires expertise across multiple domains rather than a narrow focus on a single technology. Avenga supports automotive organizations through connected vehicle systems, cloud platforms, AI initiatives, in-vehicle software development, validation services, infotainment systems, ADAS engineering, and AUTOSAR-based development.
This combination becomes particularly relevant during modernization projects where multiple systems need to evolve together.
Services include:
- In-vehicle software development
- Connected vehicle platforms
- Cloud integration
- ADAS support
- Automotive validation
- AI solutions
- AUTOSAR engineering
- Infotainment development
For OEMs evaluating long-term automotive software development services, Avenga is often considered for modernization initiatives involving both vehicle software and supporting digital ecosystems.
2. Codica
Legacy challenges are not limited to vehicles. Many automotive organizations rely on customer portals, fleet platforms, marketplaces, booking systems, and digital services that have evolved over years of development.
These products often face the same problems seen inside larger enterprise environments: outdated architectures, performance bottlenecks, growing maintenance costs, and limited scalability.
Codica focuses on modernizing and extending these digital platforms. Its work includes custom software development, cloud-based products, automotive marketplaces, mobile applications, and customer-facing systems designed to support changing business requirements.
Services include:
- Custom software development
- Cloud solutions
- Automotive marketplaces
- Mobile applications
- UI/UX modernization
- Platform optimization
- Quality assurance
- Ongoing support
Organizations looking for an automotive software development company focused on digital transformation initiatives often include Codica in their evaluations.
3. EPAM
Some modernization programs begin as technology projects. They quickly become organizational projects. Data is distributed across multiple systems. Different departments use different tools. New initiatives depend on infrastructure that was never designed to support them.
The challenge becomes less about individual applications and more about connecting fragmented environments. EPAM frequently supports organizations dealing with that level of complexity.
Its expertise spans cloud transformation, enterprise modernization, product engineering, connected platforms, and large-scale data ecosystems.
Services include:
- Enterprise modernization
- Product engineering
- Cloud transformation
- Connected platforms
- Data engineering
- Digital products
For manufacturers modernizing both technology and operating models, EPAM remains a frequent choice.
4. GlobalLogic
Many vehicle platforms were created before connectivity became a core requirement. They perform their original functions reliably, but integrating modern services can become increasingly difficult over time.
GlobalLogic focuses heavily on helping manufacturers bridge that gap. Its projects often involve embedded engineering, connected mobility, cloud services, vehicle connectivity, and software platforms designed to support modern digital experiences without requiring complete architectural replacement.
Services include:
- Connected mobility solutions
- Embedded engineering
- Vehicle connectivity
- Cloud integration
- Digital cockpit systems
- Data platforms
For organizations looking to modernize customer-facing experiences alongside core vehicle systems, GlobalLogic is often a strong contender.
5. Luxoft
Modernization projects frequently reveal an uncomfortable reality. The oldest systems are not always the biggest obstacle. The real challenge is often the growing number of systems that need to work together.
A new cloud service must communicate with existing software. Updated interfaces must interact with older components. Validation processes become increasingly complex as architectures expand.
Luxoft has extensive experience working within those environments. Its automotive expertise includes connected vehicle platforms, embedded software, digital cockpits, autonomous technologies, validation programs, and software integration initiatives.
Services include:
- Embedded software engineering
- Connected vehicle systems
- Digital cockpit development
- Vehicle integration
- Validation and testing
- Autonomous driving support
For OEMs managing large-scale modernization efforts, Luxoft remains one of the industry’s most established engineering partners.
The Biggest Risk Is Not Legacy Technology
Many modernization discussions focus heavily on old software. In practice, outdated technology is rarely the biggest risk. The larger risk is creating new complexity faster than old complexity is removed.
A manufacturer may introduce cloud platforms, connected services, analytics environments, and software-defined vehicle capabilities without fully addressing integration challenges. The result can be a more modern architecture on paper but a more complicated one in reality.
This is one reason successful modernization programs often move more carefully than outsiders expect.
Modernization Is Really About Creating Options
Automakers are not modernizing platforms simply because newer technology exists. They are doing it because future products depend on flexibility. Connected services. OTA updates. Vehicle data platforms. AI-powered functionality. Software-defined vehicle architectures. All of these initiatives require foundations capable of supporting future change.
That is ultimately what modernization efforts are trying to achieve. Not a perfect architecture. Not a complete replacement. An environment where future innovation becomes easier rather than harder.
The firms listed above are helping manufacturers move toward that goal through their expertise in automotive software development, platform evolution, and long-term engineering transformation.
