According to recent industry analysis from Market Research Future, the global automotive OEM telematics market is projected to grow from $50.91 billion in 2025 to $98.86 billion by 2035, driven by the increasing demand for connected vehicle solutions . Automotive OEM telematics connected car technology is at the heart of the modern vehicle, transforming it from a simple mode of transport into a sophisticated, data-generating platform. This integration of hardware and software enables a wide range of services, from real-time navigation to over-the-air updates, enhancing safety, convenience, and the overall driving experience.

The connected car relies on a suite of telematics technologies. An embedded telematics control unit (TCU) is the core hardware, typically using a cellular modem (4G or 5G) to connect the vehicle to the cloud . This unit communicates with the vehicle's various electronic control units (ECUs) to gather data on vehicle performance, location, and diagnostics . The data is transmitted to the automaker's cloud platform, where it is analyzed and used to deliver services to the driver through the vehicle's infotainment system or a mobile app. This connectivity enables features like real-time traffic updates and navigation with live routing, remote diagnostics that alert the driver to potential issues before they become problems, and over-the-air software updates that keep the vehicle's systems current without a dealer visit .

The benefits of connected car telematics are diverse. Enhanced safety is achieved through automatic emergency calling (eCall) and stolen vehicle tracking . Improved convenience is delivered through remote climate control and vehicle location services . For automakers, telematics provides valuable data on vehicle usage, enabling predictive maintenance and improving vehicle design . The connected car is also a key enabler for new mobility services, such as car-sharing and usage-based insurance, which rely on the data generated by the vehicle.

The connected car segment is a major driver of the market. As the automotive OEM telematics market evolves, the integration of 5G technology is expected to unlock even more capabilities, enabling faster data transfer, lower latency, and support for vehicle-to-everything (V2X) communication.
