VAUXHALL'S new Vectra is ready for police service with forces starting to take delivery of demonstrator models for a six-month evaluation period.

The police-specification Vectra shares its interior, transmission and 147PS 2.2-litre engine with the SRi.

Upgraded suspension, brakes and electrics and a specialised console which allows police to fit specific radio, light and siren switchgear have been fitted.

The 1.8-litre petrol engine version, with an option for LPG dual-fuel power, will also be available to police forces, along with a powerful 2.2 diesel engined model.

All Vectra police cars are built to Home Office specification, including electromagnetic compatibility standards designed to prevent external signals from interfering with the car's communications equipment.

Brian Tavener, managing director of special vehicles operation, which prepares all of Vauxhall's police and emergency vehicles, said: "Vectra has entered this market at a very important time as budgets force police to be more conscious of whole-life costs.

"Our reputation with the Vectra makes us confident that this model is the right product and the right time."
