The whole point of cop cars isn't acceleration. It'* durability. The Crown Vic is big, tough, fairly agile, and stable at high speed. Yes, the old Caprices were better, but the CV is better at the job than anything else on the market right now.
HOWEVER, Chrysler apparently is releasing a limited number of Hemi Magnums with a developmental Police Package. I got passed by one that the Ohio Highway Patrol is using around I-71 between Columbus and Cleveland. He was after a Cobra that was going flat out, and the Magnum reeled him in like he had a hook in the Stang'* butt.
The CV is probably gonna have serious competition for the top-dog cop-car soon, unless Ford gets smart and lets SVT have a whack at it.(Supercharged 4.6 CV, YAHOOO
