Driving Impressions: You’ll enjoy driving the Sierra Denali
The Denali is offered in 2WD and 4WD layouts. Though both are equally competent, the 4WD offers greater traction to all wheels on slippery terrains and enhances the vehicle’s stability.
The high-output 6.2-liter V-8 engine, which produces an incredible 403 horsepower, is truly a stellar performer. It delivers excellent acceleration and also improves fuel economy with its variable valve timing feature. The electronically-controlled, heavy-duty 6-speed automatic transmission with overdrive and tow/haul mode shifts seamlessly and gives a smooth ride.
The Denali is maneuvered by a power steering, which feels neither too tight, nor too light and offers prompt and precise responses. It rides on an independent front suspension with coil-over shock, while the rear suspension includes 2-stage multi-leaf semi-elliptic springs. This suspension smoothens bumps on roads and makes for a comfortable, jerk-free ride.
The Denali is equipped with 4-wheel anti-lock, 4-wheel disc brakes, which supply forceful stopping power and pull it over at short distances without screeching. The anti-lock brakes prevent locking up of wheels, thereby avoiding skidding of the vehicle. A heavy-duty automatic locking rear differential distributes power evenly to Denali’s rear wheels on slippery terrains. At lower speeds, the differential automatically detects wheel spin, locks the rear axle, and delivers torque to the rear wheel with more traction.
With a high ground clearance of 9.0 inches, the Denali can take you over uneven terrains with considerable ease, while a large turning diameter of 47.2 feet makes it a little difficult to be moved or parked in congested areas.
Safety: Engineered to protect you
The Denali comes with a bevy of safety features to ensure protection of its occupants. It comes standard with front airbags for the driver and right front-passenger with a passenger sensing system, head-curtain side-impact airbags at front and rear outboard seating positions with rollover sensor, anti-lock brakes, ultrasonic rear parking assist, and PASSkey III theft-deterrent system.
The Denali comes standard with OnStar with a one-year safe and sound service. OnStar is an in-vehicle safety and security system created to help protect passengers on the road. OnStar's innovative three-button system offers 24-hour access to expertly trained and caring advisors, a connection to emergency assistance, and access to OnStar hands-free calling.
The Denali also comes equipped with StabiliTrak, a stability control system that applies brake pressure to any individual wheel and may adjust engine speed to help keep the Denali on track and reduce the risk of vehicle roll-over.
