My department was one of the first to use midsize front wheel drive autos for patrol. We started in '84 with the Chevrolet Celebrity police package. I recall it having a 3.8 V6 which gave no better gas mileage than the previous V8 Malibus. We drove those pigs until Chevy stopped building them, then received full size Impalas with V6's. That my friends was the absolute worst ever match of engine and body conceived and produced. Lordy what a pig.
The bean counters never take into account how the car will be used. In an urban area, such as I rode, we needed a car that could drag race block by block with more brakes than horsepower. Torque and brakes saved the day for us. A puny engine had to work harder and was harder on gas.
Then you go to the traffic division where the entire day is spent on the highway. You'd think the cars requirements would be completely different. NOT, again you need blinding acceleration, and great brakes. Handling is a plus factor here as well due to speeds involved.
Detectives and some UC units can get away with eco cars, anything marked will deliver economy with performance.
