Along with cracking down on crime, police forces across the UK will also be cleaning up the streets of CO2 emissions.
With a range of 100 miles and a top speed of 81mph, Mitsubishi says the i MiEV is the ideal vehicle for urban policing duties.
The i MiEV in full police livery was showcased at the National Police Show in September, where it attracted plenty of interest from UK police constabularies.
Since then, Mitsubishi Motors has been inundated with requests from UK Police Forces to trial the i MiEV.
Mitsubishi's managing director, Lance Bradley, said: 'The i MiEVs have been in the UK on trial for almost a year now and we are delighted that police forces are able to see that the future of zero-emissions driving requires no compromise.'
The first full-production i MiEVs arrive in the UK in November 2009 and will be on the road in December 2009, with West Midlands Police being the first force to run the vehicle in full operational use.
