Super TestCar reviews - Holden - Zafira - 5-dr people-moverHolden modelsResearch Holden Steering30 Aug 2001 ZAFIRA uses an electro-hydraulic power-assisted rack-and-pinion steering system. The unit weighs approximately 1.5kg less than conventional hydraulic systems and is claimed to reduce fuel consumption by about 2-5 per cent through operation on an as-needed basis. An electronic motor driving the servo gear pump rotates at a speed of 2300rpm when Zafira is driving in a straight line when the wheel turns, electronic controls register the increased steering resistance and switch the electric motor to its working speed of 3300rpm to supply the required hydraulic pressure and flow. The turning circle is 10.5 metres and the three-spoke steering wheel contains magnesium that reduces weight by about 500g compared with a conventional design. Did you know?The telescopic steering column for the Zafira's steering system is mounted on a stable crossmember to minimise vibrationAll car reviewsAlfa Romeo Abarth Alpine Alpina Audi Aston Martin BMW Bentley Chevrolet Chery Citroen Chrysler Dodge Cupra Ferrari DS Ford Fiat FPV Foton GWM Great Wall Holden Haval HSV Honda Hyundai Hummer Isuzu Infiniti Jeep Jaguar Lamborghini Kia LDV Land Rover Lotus Lexus Maserati Mahindra McLaren Mazda Mercedes-Benz Mercedes-AMG Mini MG Nissan Mitsubishi Peugeot Opel Proton Porsche Renault Ram Rover Rolls-Royce Skoda Saab SsangYong Smart Suzuki Subaru Toyota Tesla Volvo Volkswagen |
