POLICE fleets are being targeted to participate in an operational trial of gas-powered patrol cars. Half a dozen constabularies are already involved in the programme, which is part of the Energy Saving Trust's Powershift programme, and due to be further extended at next month's National Association of Police Fleet Managers' conference and exhibition.

Bedfordshire, Hampshire, Hertfordshire, Humberside and Surrey forces have all taken Astra patrol cars converted to run on liquid petroleum gas by Vauxhall Special Vehicle Operations. The three-year Powershift programme is designed to create a sustainable market for alternatively fuelled vehicles and to raise awareness of their viability. The Energy Saving Trust hopes the 12-month exercise will act as a catalyst to further increase demand for LPG vehicles following the Government's decision to cut in duty on gaseous fuels.

Conversion costs are around £1,500 per vehicle, but the dividend is much lower fuel costs and significantly reduced maintenance. Further details about the Powershift programme are available on 0345 277200.
