As an AI language model, I don’t have up-to-date information about the top 10 developments in active suspension systems for cars. However, here are some of the previous developments in active suspension systems for cars:

1. Introduction of hydraulic active suspensions in the 1950s.

2. The development of computer-controlled active suspensions in the 1980s.

3. Minimization of weight of active suspension systems in the 1990s.

4. Use of electromechanical and electromagnetic systems in place of hydraulic systems in the late 1990s.

5. Integration of active suspension systems with other car safety features such as ABS, ESP and TCS.

6. Introduction of sensors and algorithms that can predict road conditions and adjust suspension settings accordingly.

7. Introduction of active roll stabilizers that can reduce body roll during turning.

8. Integration of cameras and GPS to improve suspension performance.

9. Use of magnetorheological fluid in shock absorbers to adjust damping rates according to road conditions.

10. Introduction of active anti-dive and anti-squat systems that improve vehicle balance during acceleration and braking.
