An electronic ('intelligent' or 'active') suspension system can control the vertical movement of a vehicle's wheels relative to its chassis or body via an on-board system. Given that a conventional passive suspension system features a fixed damper setting, there has always been a compromise between comfort and handling performance. Yet electronically controlled suspension systems that continuously adjust the damper settings to suit the road conditions eliminate that trade-off, providing the driver with greater levels of comfort and control. This month's briefing reviews the market prospects for electronic suspension systems and some of the major players.
