How Does Dynamic Response Work in the Range Rover Sport?

Why It's Needed

Dynamic Response is designed to reduce the risk of rollover during tight turns. In the past, rollovers have been a major concern for many sport/utility vehicles. The reason behind this is simple: SUVs have a high center of gravity. Because of their height, high-speed maneuvering into tight corners can sometimes cause the vehicle to tip and roll. This problem is usually corrected by changing driving styles and maneuvering at lower speeds. The Range Rover Sport, however, is designed as a high-performance SUV. To maintain this performance, the Dynamic Response system was added.

How It Works

The Dynamic Response system works by sensing high-speed cornering forces and acting to compensate. The system is controlled by a computer. Sensors throughout the vehicle constantly measure G-forces, the forces affecting the SUV during tight cornering. These signals are sent to the computer. When cornering forces begin to roll the vehicle, the system automatically adjusts the air-spring suspension. This compensates for the roll and reduces pitch.

How This Helps

The Dynamic Response system is designed to adjust automatically, without driver input. Without this technology, a driver would have to constantly adjust his speed and cornering to keep the SUV on the road. Dynamic Response changes this, letting drivers focus on the road instead of worrying about managing rollover risk.

The system also helps during off-road use. If terrain requires extended wheel travel, the computer can loosen the suspension and give the wheels more freedom. Vehicles usually have suspensions tuned for either on-road or off-road handling, but not both. On the Range Rover, however, the Dynamic Response allows the driver to master both conditions.
