For the purpose of these calculations, we will use a comparison of the duty-proven Ford Police Interceptor Sedan with the new Police Responder Hybrid Sedan. While driving, the estimated fuel economy of the Police Responder Hybrid Sedan compares favorably against the Police Interceptor Sedan (projected EPA-estimated rating of 38 combined mpg1 vs. EPA-estimated combined rating of 18 mpg2 ). To start, 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. Projected EPA-estimated rating of 40 City/36 Hwy/38 Combined mpg. Actual mileage will vary. Final EPA-estimated ratings not yet available.
2. EPA-estimated rating of 16 City/22 Hwy/18 Combined mpg, 3.7L Interceptor Sedan 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 80 degrees F. The following vehicle accessories were activated during the test: climate control AC, set to full cool condition; vehicle audio system, set to 33% 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).
