active roll stabilization 
Active roll stabilization winds up the stabilizer bars in the front and rear suspension to resist body lean while cornering. Because cars use active control only as needed, the technology reduces vehicle spring rates and stabilizer bar stiffness, resulting in a smoother ride. In addition, this system can also increase low-speed, off-road traction on four-wheel-drive vehicles--meaning you're less likely to take your SUV over the side of a cliff.
