Car reviews - Holden - Astra - SRi 3-dr hatch
15 Mar 2002
HOLDEN says the Astra is one of the few cars to use an electro-hydraulic steering system. Working through an otherwise conventional rack-and-pinion system, the Astra's steering is claimed to assist in more economical operation because it uses less power than a conventional assisted system when the wheel is not being turned. When the steering wheel is turned, the maintenance-free electric motor, rotating at a stand-by speed of 2300rpm is actuated to a working speed of 3300rpm. A decoupled subframe module incorporates the steering mechanism, lower suspension arms, cooling system and an engine-carrying mount. An additional system cross-member between the A-pillars acts as a stable anchor for the energy-absorbing steering column, decoupling it from the windshield cross-member and front bulkhead to reduce penetration into the cabin. The Astra's turning circle is a tight 10.3 metres and the wheel goes from lock to lock in 3.3 turns.
