When Volvo launched its petrol mild-hybrid XC90 in India at Rs 89.90 lakh, most coverage focused on horsepower, luxury features, and pricing. But beneath the surface, modern vehicles like this one are essentially computers on wheels—and that shift carries serious cybersecurity implications that every driver should understand.
The XC90 showcases how far automotive technology has come. Its infotainment system offers extensive connectivity features, the driver assistance suite relies on sensor networks and real-time data processing, and features like the cabin air cleaner with PM 2.5 filter can be monitored and controlled remotely through smartphone apps. Each of these systems represents a potential entry point for malicious actors.
The Attack Surface Expands
Modern vehicles contain dozens of electronic control units (ECUs) communicating over internal networks. The Volvo XC90's advanced driver assistance systems (ADAS)—including adaptive cruise control, pilot assist, blind spot monitoring, and collision mitigation—depend on data from cameras, radar, and lidar sensors. When these systems connect to external networks for over-the-air updates or remote diagnostics, they create attack surfaces that didn't exist in earlier vehicle generations.
Connected car security risks emerge from several vectors. Telematics units that enable emergency services and smartphone integration can potentially be exploited if not properly secured. Third-party apps that interface with vehicle systems introduce additional risk when developers don't follow secure coding practices. Even seemingly innocuous features like the 12.3-inch digital instrument cluster or the Bowers & Wilkins audio system may contain processors that could theoretically be targeted.
The automotive industry has historically lagged behind consumer electronics in security maturity. While Volvo has built its brand around safety, traditional cybersecurity practices—regular patching, intrusion detection, secure boot mechanisms—vary widely across manufacturers and model lines.
What This Means for You
Say you own a connected vehicle and receive a notification about a software update. The question isn't just whether to install it, but whether you understand what systems are being modified. Modern car updates can affect braking, steering assistance, and airbag deployment—not merely infotainment preferences.
Your vehicle likely collects more data than you realize. Location history, driving patterns, smartphone contact lists synced through Android Auto or Apple CarPlay, and voice command recordings may be stored locally and transmitted to manufacturer servers. Understanding what data your vehicle collects and how it's protected matters as much as knowing its horsepower.
The Bigger Picture
Volvo's transition toward electrification—with the XC40 Recharge arriving in early 2022—will only intensify these concerns. Electric vehicles typically feature more sophisticated software systems, bidirectional charging capabilities, and deeper integration with home energy management. Each advancement adds complexity and potential vulnerability.
The industry faces pressure to deliver continuous feature updates while maintaining security—a balance that even established tech companies struggle to achieve. Regulatory frameworks for vehicle cybersecurity remain fragmented globally, leaving consumers dependent on manufacturer commitment to security practices.
Key takeaways

- Connectivity features enabling smartphone integration, remote diagnostics, and over-the-air updates all require solid security measures
- Vehicle data collection extends beyond location to driving patterns, contact lists, and voice recordings stored locally and on manufacturer servers
- The shift toward electric vehicles intensifies cybersecurity concerns due to increased software complexity and home energy integration
Frequently asked questions
How does the Volvo XC90's connectivity create cybersecurity risks?
Features like smartphone integration, remote diagnostics, and over-the-air update capabilities create network entry points that could potentially be exploited by malicious actors if not properly secured with encryption, authentication, and regular patching.
What data does a modern connected car like the XC90 collect?
Connected vehicles typically gather location data, driving patterns, smartphone contact lists synced through integration systems, and voice command recordings. This data may be stored locally and transmitted to manufacturer servers with varying privacy protections.
How do automotive cybersecurity risks compare to traditional cybersecurity concerns?
Vehicles introduce unique challenges because compromise can affect physical safety through braking, steering, or airbag systems. Unlike a compromised computer that might lose data, a compromised vehicle could directly endanger lives.
Are traditional car manufacturers as security-mature as tech companies?
Generally, the automotive industry has lagged behind technology companies in cybersecurity practices. While Volvo emphasizes safety, security maturity varies widely across manufacturers, and regulatory requirements remain inconsistent globally.
Will the shift to electric vehicles make cybersecurity concerns better or worse?
Electric vehicles typically contain more sophisticated software systems and deeper home energy integration, which will likely intensify cybersecurity concerns. The XC40 Recharge and similar EVs introduce additional complexity through bidirectional charging and home energy management features.
