The 2002 GMC Sierra Denali’s new four wheel steering is so addictive that once you drive the full-size pick-up truck equipped with Quadrasteer, you’ll find yourself taking drives in parking lots just to show off how well the vehicle completes a full circle. (It’s a much tighter turning diameter than what a Chevrolet Corvette can turn.) The four wheel steering system makes parallel parking a snap. Simply put: this is a terrific technology for a full size vehicle. Sierra Denali – previously Sierra C3-badged – is a 4-door truck. (Front door must be open to access rear door.) The 2002 Sierra also sports a more pronounced tailgate badge. Sierra Denali décor includes air conditioning, AM/FM stereo cassette with 6 CD changer, steering wheel audio controls, heavy-duty trailer/towing equipment, 17-inch aluminum wheels, remote keyless entry, rear window defogger, and fog lamps. The pick-up truck offers comfortable seats, good views (including the side mirrors), and a well-appointed, well-positioned interior environment. Fuel estimates are 12 city/15 highway. The Sierra Denali driven on a mega-mileage test-drive left a lasting impression of power (6.0-liter V8 engine mated to 4-speed automatic transmission) and nimble maneuvering. Suggested base price of the Sierra Denali is $43,385.
