Fuel Mileage T e Fuel Effi ciency Test simulates real-world conditions conducted over a 100-mile course. T e protocol uses patrol deputies, in full uniform, to drive each vehicle through this course. Each vehicle is driven through the course four times with diff erent drivers, dur- ing peak (rush-hour) traffi c conditions. T e course is divided with urban, suburban and freeway driving conditions. Headlights and air conditioning are turned on and the transmis- sions are placed in the default Drive position. T e vehicles are driven in a normal manner,


i.e., neither “babied” nor driven for maximum performance. T e fuel mileage obtained from each run is then averaged out. By defi nition, this test simulates the mileage that a detective or administrative vehicle would obtain. Experience shows that a marked patrol unit would obtain about 60 to 70 percent of these mileage fi gures. T is year, there was a three-way tie for fi rst


between the Chevrolet Impala 3.6L V6, the Dodge Charger 3.6L V6, and the Chevrolet Caprice 3.6L V6. All three attained at 20 mpg. At 19 mpg were both versions of the Ford PI Sedan, i.e., the 3.7L V6 AWD gets as good of mileage as the 3.5L V6 FWD while delivering better acceleration and driving performance.

Subjective Evaluations After the evaluation, each deputy then fi lls out a checklist rating their impression of each individual vehicle. T e evaluations are con- ducted separately and the ratings are averaged to minimize any individual prejudices for or against any of the vehicles. Vehicles are evalu- ated for general suitability and effi ciency as a patrol vehicle, or other specifi c functions that the LASD may require. (Ed. Note: T ese driver comments are used as photo captions.) While the Los Angeles County Sheriff ’s Department does not recommend any specifi c vehicle or other equipment, such as tires, their complete test results are published annually and are available on their website.
