A fire engine (also known in some territories as a fire apparatus, fire truck, or fire appliance) is a vehicle designed primarily for firefighting operations. In addition, many fire departments often employ their vehicles for various other uses including emergency medical services and rescue purposes. The terms "fire engine" and "fire truck" are often used interchangeably but in North America represent different types of vehicles.

The FIRE (for "Fully Integrated Robotised Engine") is a series of automobile engines from Fiat Powertrain Technologies, built in FCA's Termoli, Betim and also in Dundee (only in 1.4 Multiair versions) plants. It was designed by Italian design firm Rodolfo Bonetto. It is constructed by robot assembly plants ("Robogate") to reduce costs.
