For the purpose of these calculations, we will use a comparison of the previous-generation Ford Police Interceptor® Utility with the all-new 2020 Ford Police Interceptor Utility hybrid. For starters, the projected fuel economy of the next-generation Police Interceptor Utility hybrid compares favorably against the previous-generation Police Interceptor Utility, with a projected EPA-estimated Combined rating of 24 mpg1 vs. the EPA-estimated Combined rating of 17 mpg.2 Here are some sample calculations. These will utilize the same formulas used to determine your potential savings:
Entering any unrealistic combination of data will negatively impact the accuracy of results shown.
1. EPA-estimated Combined rating of 24 mpg, Interceptor Utility Standard HEV AWD. Actual mileage will vary.
2. EPA-estimated Combined rating of 17 mpg, 3.7L Interceptor Utility AWD with unleaded gas. Actual mileage will vary.
3. Idle duration data collected with the assistance of Dearborn Police Department and Massachusetts State Police, April 2012–November 2013. Data collected on a total of six vehicles in police patrol use.
4. Idle fuel consumption estimates are based on fuel flow measurements taken during two hours of continuous idling. Vehicles were driven for 18 miles at highway speeds prior to idling. Idle testing was conducted in an indoor facility at 73 degrees F. The following vehicle accessories were activated during the test: climate control AC, set to full cool condition and the vehicle audio system, set to 30 percent of maximum volume. An electrical power draw load box drawing 32 amps was also connected to each vehicle’s 12-volt battery to simulate the following estimated police accessory loads: emergency lights (est. 25 amps); laptop computer (est. 3 amps); police radio (est. 4 amps) Additional testing details are available at https://ford.to/2H9qBEf.
5. Burning a gallon of E10 ethanol fuel produces about 17.68 pounds of CO2 emitted from the fossil fuel content, according to data provided by the U.S. Energy Information Administration (http://ford.to/eiareport).
