The disadvantages of front-wheel drive are a matter of driving style. Some officers who worship acceleration say that front-wheel-drive patrol cars are not as fast off the line as their rear-wheel-drive counterparts. Of course, this is more a function of engine than it is drive train.
Another slam against front-wheel-drive cars is that they can be more expensive to service and repair. Fleet managers say that, as long as their mechanics are familiar with the vehicles, this really isn’t a major concern. However, front-wheel-drive cars can be tricky to repair because everything—the engine, the drive train, and the differential—is in the same general place. All that crowding can make working under the hood unusually complicated.
But perhaps the most damning criticism of the current crop of front-wheel-drive cop cars involves their ground clearance, an issue that is independent of their drive trains. Helmick says Pinellas County has experienced some issues with bottoming out. “The Intrepid is a half inch lower than the Crown Vic,” he explains. “Some of our guys have ripped off the front air dams when hopping curbs.” For these and other reasons, patrol cops tend to prefer big, rear-wheel-drive cars. But if you ask fleet managers and administrators what they want, you’ll hear another story.
With regular unleaded tickling the $2.50 per gallon level, gas mileage has become a huge issue for police fleet managers. The EPA says the Impala gets about five miles per gallon more than the Crown Vic. Fleet managers say that the Impala’s EPA rating of 23 MPG is a fantasy for a patrol car that spends an awful lot of time at idle, but it does get slightly better mileage than the Crown Vic.
Helmick says fuel economy is definitely one of the reasons that he likes to have front-wheel-drive, 3.5-liter Dodge Intrepids in the Pinellas County Fleet. “Fuel economy is a huge thing for us,” he explains. “Our Crown Vics in real world use get eight to nine miles per gallon. With the Intrepid we get 11 to 13 miles per gallon.”
