Still rear-wheel drive with its body mounted on a separate frame, the latest Crown Victoria debuted in March 1991. Only a 4-door sedan was offered, in base or LX trim. Mercurys Grand Marquis is similar. Four-wheel disc brakes and a driver-side airbag were standard; antilock braking and a passenger airbag optional. A new 4.6-liter overhead cam V8 made 190 horsepower (210 with dual exhausts). As the full model year opened, Ford added a Touring Sedan with handling/performance package and traction control.Quite a few revisions were evident, led by a revised grille and taillamps, new bumper fascias, new trunk (with wider, lower opening), and color-keyed bodyside moldings. Dashboards wore new woodgrain trim and displayed outside temperature and gallons to empty, door switches gained backlighting, and the front seat got more rearward travel.
