Core Viewpoint - The 2025 model of L9 shows significant improvements in body motion control compared to the previous model, particularly in aspects like roll, pitch, and handling on uneven surfaces, although there is still room for improvement in steering feel and unsprung mass vibration control [1][8]. Suspension Comfort - The suspension comfort is rated 9 out of 10, with the comfort mode outperforming the sport mode. The vehicle maintains excellent performance in vibration isolation, road noise control, and seat comfort. However, the improvement in handling large impacts like potholes and speed bumps is minimal compared to the previous model [2]. - The second-row vibration isolation has improved, addressing the previous model's issues with rear seat vibrations. The vehicle exhibits excellent body motion control, particularly in bridge transitions, showcasing the advantages of the dual-valve CDC system [2]. Steering Control - The steering control is rated 7.5 out of 10, showing noticeable improvement over the previous model, although the absolute score remains relatively low [3]. - The vehicle features Michelin PS4 SUV tires, providing excellent grip and stability during cornering [4]. - The torque distribution strategy and TCS calibration are commendable, resulting in a neutral steering response with a low understeer tendency [5]. - However, the tire sidewall stiffness is lower for comfort, leading to a vague steering center and non-linear response, particularly noticeable during small-angle steering inputs [6]. - The overall steering feel is acceptable, but quick lane changes reveal excessive damping, especially during rapid return to center [7]. Summary - The new L9 model with dual-chamber air springs and dual-valve CDC demonstrates significant enhancements in body roll and pitch control, resulting in a more stable and compact driving experience. Recommendations include increasing tire sidewall stiffness for improved steering linearity and addressing unsprung mass vibration control [8]. - Overall, the L9 is considered an excellent family SUV in its price range, worthy of recommendation [9].
