Design upgrades for the 2006 Cadillac STS-V include a chrome mesh grille above and below the bumper that aids engine cooling by 34 percent; integrated front fog lights; a raised dome hood that hides the supercharger and gives the Caddy a more powerful appearance; rocker panel extensions; and front and rear fascias that sit lower to the ground; dual chrome exhaust tips; a deck lid spoiler that’s 14-mm higher than normal; and 10-spoke alloy wheels. Inside is a hand-sewn, 100-percent genuine leather interior with ultra-suede inserts, and olive ash burl wood trim is used on the instrument panel, shifter surround, and door grab handles.
