The engine, which delivers 350lb.ft. of torque, has been available in a variety of Ford vehicles, including the Police Interceptor sedan, and is the choice for more than 40 percent of Ford F-150 truck buyers.

‘We continue to look at ways we can offer our customers additional product enhancements to further meet their unique needs,’ said Gerry Koss, Ford fleet marketing manager. ‘Our Police Advisory Board and customers across the country identified the EcoBoost engine as their No. 1 want in the Police Interceptor utility vehicle.’

Since the new Ford Police Interceptor products were launched in 2012, the utility model accounts for half of the company’s police vehicle sales thanks to its ability to store large amounts of equipment whilst still offering first-responder, pursuit-capable performance and handling.

The new unit joins the standard 3.7-liter Ti-VCT V6 engine, which delivers 304hp and 279lb.ft. of torque.

‘The 3.5-liter EcoBoost will offer best-in-class performance and top-notch fuel economy,’ said Bill Gubing, chief engineer for Police Interceptor. ‘That means law enforcement agencies that require this level of capability won’t have to compromise.

‘It also complements our strategy of offering a choice of either sedan or utility vehicle based on a common platform, and sharing a large amount of common components, including powertrains, brakes, wheels/tires, seats and maintenance items,’ Mr Gubing added.
