There are a number of different types of active suspension including pneumatic and magnetic , but to my knowledge, in practice, these are all classified as semi-active, since there are other non-active components (e.g. spring and sway bars) that are also part of the vehicle's suspension. It seems to me that if we could have a single actuator at each wheel and omit all of the currently used passive components (and their weight!), that this would be very attractive for some applications in which cost is not the major impediment, such as some racing series and for some very high end sports cars.

To answer your specific question, no, there are no technical impediments. That said , there are reasons why passive components are still used. Cost As you might have guessed, cost is potentially the biggest reason active suspensions are still uncommon. You mention some applications where cost is less important (it's never unimportant), but consider cost per performance vs simple cost. A well designed passive suspension will handle a majority of driving cases, will only have a single resonant frequency (ignoring harmonics, which are hard to activate on a vehicle), and generally perform well to minimize NVH. These systems cost very little to implement because we've used them for quite some time now. As such, incremental gains to existing passive suspensions don't require extensive investment and always provide increasing levels of performance. The cost per performance, then, is minimal. On the other side, active suspensions allow for perfect body control. You can completely isolate the c
