Even though Volvo is keen to spotlight its electric models, the tried-and-true XC90 is still not to be missed. But is it still competitive? Our practical test shows what each Volvo SUV can do.
Visually, the 'big boys' of the 90 series look quite similar. As early as mid-September, Volvo presented the latest versions of the EX90 and XC90 in Gothenburg, Sweden. The test drive took place in early February with the electric variant through Hamburg, and finally, the evergreen presented itself as a mild hybrid and plug-in hybrid in the Bavarian Alps around Berchtesgaden. The Scandinavians still sell numerous models of the XC90, which first appeared under this name in 2002.
While the XC90 impresses as an established premium SUV with modern infotainment integration and proven driver assistance systems, the all-electric EX90 presents itself as a technological advancement with a new software architecture, extensive sensors, and innovative safety solutions. Our test highlights the differences between the two models in the areas of infotainment, driver assistance systems (ADAS), connectivity, as well as the installed chips and software architecture.
XC90: Proven user interface with Google integration
The Volvo XC90 integrates a modern version of the Android-based infotainment system, which ensures relatively intuitive operation. The central 11.2-inch touchscreen is freestanding in the centre console and offers a clear menu structure with context-related controls. The integration of Google services such as Maps, Assistant, and the Play Store allows seamless integration into the users' digital ecosystem.

The infotainment system also offers over-the-air updates, allowing new features and software improvements to be continuously implemented. Apple CarPlay is available wirelessly, which also facilitates connectivity for iPhone users. The driver display, measuring 12.3 inches, provides all essential driving information in high resolution and can switch between different display modes. The system is complemented by an optional head-up display that projects driver-relevant information directly into the field of vision.
In general, Volvo has tried to simplify the HMI once again, which has been quite successful. It takes little time to become familiar with the setting options.
EX90: Infotainment platform with core computing
With the EX90, Volvo relies on an advanced infotainment platform based on powerful core computing. The central 14.5-inch touchscreen with a frameless design is high-resolution and offers enhanced user guidance with context-based displays. The system operates with a new software architecture that enables faster data processing and better adaptability to future functions.
A crucial difference is the underlying hardware. While the XC90 uses a classic decentralised control, the EX90 features two central high-performance computers. The Vehicle Control Unit (VCU) with an Nvidia Xavier chip (30 teraflops of computing power) controls the general vehicle functions, while another computer with an Nvidia Orin chip (250 teraflops) is responsible for the assistance systems and autonomous driving. This architecture reduces the number of individual control units and enables more powerful OTA updates.
The connectivity of the EX90 is enhanced by a 5G-capable internet connection, allowing for higher data transfer rates and real-time communication with other vehicles and infrastructures. Another innovation is the digital key function, which uses the smartphone as a vehicle key. Additionally, Google HD Maps is integrated into a Volvo for the first time, enabling more precise navigation and improved use of ADAS functions.
Volvo relies on high-quality audio systems in both models, which can vary depending on the equipment line. As standard, both the XC90 and the EX90 are equipped with a high-performance sound system with ten speakers. The EX90 offers slightly more power here with 325 watts compared to the XC90 with 220 watts.
In the higher trim levels, Volvo relies on different partners: In the XC90, the sound system comes from Harman/Kardon with 600 watts, 14 speakers, and an integrated subwoofer. In the EX90, the Bose system is intended to provide an even more intense sound with 940 watts, 14 speakers, and advanced surround technology.
Our test vehicles were both equipped with systems for the highest sound quality. The Bowers & Wilkins Sound System in the XC90 with 1,460 watts, 19 speakers, and the proven Tweeter-on-Top technology is truly impressive, but the EX90 offers me 1,610 watts, 25 speakers, and Dolby Atmos for a slightly more intense 3D sound experience. Additionally, four speakers are integrated directly into the headrests of the front seats to enable individual audio outputs for phone calls or navigation instructions. Visually, the sound system in the EX90 blends seamlessly into the Scandinavian design, with backlit stainless steel grilles and a central media control knob in a jewel design. In practice, it is honestly just as much fun to turn up the sound.
Sensors and Driver Assistance Systems
A key difference between the two models lies in the sensor platform used. The XC90 relies on an ADAS platform that combines cameras, radar, and ultrasonic sensors. These systems enable functions such as adaptive cruise control, lane-keeping assist, and an emergency braking system with pedestrian and cyclist detection. Additionally, Connected Safety is on board, allowing Volvo vehicles to exchange information about road conditions and hazards with each other.
The Volvo EX90 takes a step further with an enhanced sensor system. In addition to cameras, radar, and ultrasonic sensors, the model features a lidar sensor integrated into the roofline. This enables more accurate object detection, allowing obstacles or other road users to be identified early. Combined with the new software architecture, this lays the foundation for future autonomous driving functions.
Both vehicles use the Pilot Assist System, which enables semi-automated driving on motorways. While the XC90 relies on traditional sensors, the EX90 benefits from its enhanced sensors with higher precision in environmental perception. This is complemented by a driver monitoring system that uses infrared sensors to monitor the driver's attention. In tests, the system reliably detected whether the driver was tired or distracted and issued warnings. In an emergency, the vehicle would even be braked to a standstill.
Nvidia's Role in Volvo's Safety Software
Volvo is increasingly relying on AI and virtual environments to further develop its safety software. Collaboration with Nvidia is playing an increasingly important role. The latest generation of Volvo models, including the EX90, uses high-performance computers from Nvidia to efficiently process sensor data and further develop driver assistance systems.
A particular advancement is the use of so-called "Gaussian Splatting," an innovative rendering technique that enables the creation of realistic 3D environments based on real sensor data. With this technology, Volvo can create virtual driving scenarios to simulate and analyze rare but potentially dangerous traffic situations. The insights gained from this directly contribute to the further development of driver assistance systems to further optimize the responsiveness of sensor platforms.
Additionally, the cooperation with Nvidia is creating an AI supercomputing platform based on the DGX systems of the US tech company. This platform is used to process large amounts of data from real and simulated driving scenarios and supports the continuous improvement of AI models for future vehicle generations.
Conclusion
The Volvo XC90 offers a proven combination of modern infotainment, comprehensive safety features, and strong Google integration. It remains a premium SUV with high-quality driver assistance systems and a solid connectivity solution. The Volvo EX90, on the other hand, brings a new generation of vehicle architecture to the market. With core computing, lidar technology, AI-supported driver monitoring, and 5G connectivity, Volvo is focusing on forward-looking solutions. The EX90 is intended to be not just an electric SUV for Volvo, but a technological milestone.
Despite the many optimisations and developments: In practical tests, the differences between the models were less noticeable. The decision to refresh the XC90 once again also seems sensible for technological reasons, as the evergreen XC90 can still hold its own in its 23rd year.
