We think it’s safe to say all SRT vehicles end up looking better than the mainstream models on which they’re based. That said, the 2006 Jeep Grand Cherokee SRT-8 is probably the team’s best-looking makeover to date, in both an absolute sense and in terms of the way it completely transforms the look of the vehicle.

SRT designers started by giving the Grand Cherokee special bodywork that’s just as much about “go” as it is “show.” In wind tunnel tests, the front air dam was proven to reduce both lift and aerodynamic drag, while also funneling cool air to the brakes and massive motor. Side sill extensions also help create downforce, while the rear valance nicely integrates those way-bad four-inch exhaust pipes.

Just as significant as what the SRT team added is what they left out. The notable lack of both body cladding and a roof rack contribute greatly to both the design’s clean appearance and its improved aerodynamics. The Grand Cherokee SRT-8 is offered in just three colors, but they’re three good ones: Bright Silver, Inferno Red, and Batman’s favorite, Brilliant Black.

Inside the changes are more subtle, but no less effective. Excellent leather-clad sport seats with substantial side bolsters and faux suede fabric inserts help keep your kiester planted during enthusiastic motoring. A carbon-fiber pattern in the leather on the steering wheel and shift knob offers both good looks and a better grip than the smooth leather trim traditionally used on these surfaces.

Speaking of trim, the 180-mph speedometer, tachometer, fuel level and coolant temperature gauges are set into a carbon-fiber housing, while oil pressure and temperature can be monitored on a separate LED display. Satin-finish aluminum trim on the center stack, shifter surround, and door panels add just the right touch of brightness to the vehicle’s dark gray interior.

Just because the 2006 Jeep Grand Cherokee SRT-8 looks good and goes fast doesn’t mean it’s unsafe. All-wheel drive, four-wheel antilock brakes with brake assist, and electronic stability control are standard. The stability control can be partially disabled for use on the race track, but given its minimally intrusive nature we think most buyers will be better off leaving the dash-mounted switch alone.

Power-adjustable accelerator and brake pedals, which allow shorter drivers to sit a safe distance from the steering-wheel-mounted airbag, are also standard. While head-protecting side-curtain airbags – an absolute must-have safety feature in our book – aren’t included on the standard equipment list, they are available as an option.
