Police chiefs in South Yorkshire have invested in 10 new electric cars - aimed at saving £25,000 over 10 years.
The environmentally friendly Vauxhall Ampera cars were bought following a trial in Sheffield earlier this year.
They will be used to carry out inquiries and for officers to visit victims of crime and take statements. They will not be used to respond to emergencies or in pursuits.
It is hoped the force will save a total of £25,000 over the life of the 10 vehicles through reduced running costs compared with traditionally fuelled vehicles.
Sarah Gilding, head of vehicle fleet management for South Yorkshire Police, said: “Over the coming years parts of our fleet will need to be replaced and it could be that vehicles such as this could form an important part of our day-to-day activities.
“The vehicles will offer significant whole-life savings and environmental benefits and we believe they can fulfil a key role in 21st Century policing.”
Police and Crime Commissioner Alan Billings said: “This innovative approach to the vehicle fleet has given us a chance to make a genuine saving that can be used to ensure that front-line policing does not suffer at the hands of austerity.”
There are 13 charging points for the police vehicles across the county.
