One of the GM provided performance indicators that demonstrates how dramatic turning execution is improved with Quadrasteer is that when the Sierra Denali is changed from 2WS to 4WS, the turning diameter is reduced by almost 10 ft`it drops from a 46.2-ft turning circle diameter down to 37.4-ft. That's just about the turning radius of any compact coupe. The one caveat we'd offer is that when trailering in 4WS at slow speeds in tight corners, if the weight distribution device is installed on the tongue of the trailer, making a tight turn (previously not possible without four-wheel steer) could potentially damage the device. Check this out with the manufacturer or the service center where you purchased and had it installed.
With the one exception of the slightly flared rear wheelwells that accommodate the larger Dana axle and the additional room required for the rear- wheels steer, the Denali looks like any other Sierra 1500, with a few tow-friendly tricks up its sleeve.
