I have to wonder--the Vics that were for police, they usually got deeper rear gearing, and might not have the best of snow tires? I mean, they probably had to have a snow tire rated for 100mph or whatever. Not sure how they balance high speed with snow traction. Anyhow, point is, a lower power FWD Taurus might have the edge over a RWD Panther? but that might change on a civilian Vic with tall gears. Albeit a cruiser probably has more junk in the trunk for ballast over the wheels. A whole lot of variables to unpack there.... that really don't matter as both are basically out of departments now.
I still prefer FWD over RWD in the snow, but I really liked my part time 4WD truck in snow. Way too easy to get in over my head in RWD, but in 4WD I don't think I met something it couldn't handle... I'm sure I could have, I just didn't. Extra ground clearance for the win (gotten many a FWD stuck going uphill when snow packed under it).
