Advancing Vehicle Performance Levels
Unlike traditional passive suspensions with fixed characteristics, our controllable MR Suspensions react to vehicle and terrain conditions thousands of times per second, allowing the suspension to adapt its characteristics to the situation. This provides improved dynamic stability over passively damped systems.
Demonstrated Benefits
Faster
- 30-50% increased speed over terrain
- 30% improved maneuverability/safe driving speed
Smoother
- 50% reduced driver/passenger absorbed power
- 60% reduced peak loads into vehicle
- 40% reduced pitch and roll motion of hull
- Longer vehicle life - reduced life cycle costs
Safer
- Reduced risk of roll-over
- 30% reduced roll-rate
