Today’s cars are basically computers on wheels. Software powers features like lane-keeping, adaptive cruise control, smartphone integration and with over-the-air updates, manufacturers can fix bugs or add new features without a trip to the dealership. As we move toward software-defined vehicle and self-driving vehicles, software isn’t just part of the car—it is the car.
The automotive software boom has created entirely new feature sets and functionality. Tesla has pioneered the use of Over-the-Air (OTA) updates to securely enhance vehicle functionality and performances, while Audi is deploying cellular Vehicle-to-Everything (C-V2X) communication to improve road safety.
These breakthroughs are part of a broader digital transformation, where vehicles are evolving into sophisticated, connected systems—integrating technologies like OTA, V2X, sensors, cloud, and edge processing. This shift is not just about convenience or personalization; it’s about embedding intelligence and autonomy into the driving experience. However, with this transformation comes a new frontier of risk: cyber threats targeting the vast software and electronic architecture within modern vehicles.
Cybersecurity is integral to automotive quality. Recognizing this, standards like ASPICE have introduced a dedicated “Cybersecurity Engineering Process Group” to ensure that security is embedded into every stage of vehicle development.
As vehicles evolve into rolling data centers, cybersecurity has become as critical as horsepower or fuel efficiency. According to McKinsey, modern cars can contain over 100 million lines of code, and by 2030, software will account for up to 30% of a vehicle’s total value. This digital transformation—driven by autonomous, connected, electric, and shared (ACES) technologies—making vehicles high-value targets for cyberattacks. “Cybersecurity is becoming a new dimension of quality for automobiles,” McKinsey notes, emphasizing that vulnerabilities in connected systems can compromise not just data, but human lives.
Reinforcing this urgency, IBM’s Cost of a Data Breach Report 2024 reveals that the average cost of a data breach in the transportation sector exceeds $4 million, and a third of organizations are increasing their application security budgets by more than 5% to mitigate these risks. Delays caused by late-stage vulnerabilities can push vehicle launches back by up to a year—costing millions in lost revenue.
With the UNECE WP.29 regulations mandating cybersecurity and over-the-air (OTA) update capabilities for market access, Original Equipment Manufacturers (OEMs) and suppliers must now embed security into every layer—from chip to cloud. In this high-stakes environment, robust cybersecurity isn’t just a risk mitigator—it’s the foundation of trust, compliance, and profitability in next-generation mobility.
