Does the Volvo XC60 have a rollover prevention system?

Volvo XC60 is equipped with a rollover prevention system. The RSC (Roll Stability Control) system is one of the many active safety systems. Compared to ESC/ESP, it is primarily designed for high-friction road surfaces, relatively lower in cost, and easier to implement. The rollover stability system is a device that prevents vehicle rollovers. It monitors the vehicle's steering speed when turning on off-road surfaces, calculates the degree of vehicle roll based on signals from wheel sensors, and applies additional control to the outer wheels in a curve. When severe roll is detected on any side, the system quickly adjusts the braking force distribution between the wheels and reduces engine torque output to restore vehicle balance in the shortest time, minimizing the risk of rollover and ensuring the safety of occupants. The RSC system uses a gyroscopic sensor. During sharp turns or rapid steering by the driver, it automatically records the rate of change in the vehicle's tilt angle. Based on this rate, it calculates the final tilt angle to assess the risk of rollover. If a rollover risk is detected, the system activates the braking system to stabilize the vehicle, giving the driver time to handle the situation safely. The RSC system's electronic control unit includes a lateral acceleration sensor that continuously measures the vehicle's lateral acceleration and calculates the critical acceleration limit. When lateral acceleration approaches this limit, the system activates the ASR solenoid valve and the ABS solenoid valve on the drive axle to apply braking, slowing the vehicle down. For tractor-trailers, an additional solenoid valve is activated to send a braking signal to the trailer control valve, applying brakes to the trailer as well.
As a veteran XC60 owner with five years of driving experience, I can confidently tell you that this vehicle comes standard with a rollover prevention system across all trims. This system continuously monitors the vehicle's posture. When navigating mountain roads or performing emergency evasive maneuvers, if excessive body roll is detected that could lead to a rollover, it immediately intervenes by controlling engine power output while precisely braking the outer wheels to stabilize the vehicle. During a mountain trip, I distinctly felt the system subtly activating during consecutive sharp turns, keeping the vehicle firmly planted. Combined with the ultra-high-strength boron steel roof and pillars that maintain structural integrity even in actual rollover scenarios, Volvo truly spares no expense when it comes to safety performance.
Just tested the latest XC60's chassis system and found its anti-roll technology is integrated into the electronic stability program. Sensors monitor lateral acceleration in real-time, automatically activating before the vehicle reaches critical roll angles, working with the adaptive chassis to instantly lower the center of gravity. This system might not be noticeable during lane changes on urban expressways, but it's particularly effective during high-speed sharp turns or off-road sections. Last week, while driving my family on mountain roads, I clearly felt the system intervene when navigating a steep slope curve. The body sway was much smoother than expected, making the drive feel significantly more secure.
