This heavy full-frame luxury truck drives like a very large car. It's no sport
sedan, but it is more agile, sure-footed and Cadillac-comfortable than most any other full-size...
... truck you'll encounter, at least in part due to its fully-boxed frame, redesigned suspension, wider tracks and new rack-and-pinion steering. Both braking and steering feel, especially, are vastly improved compared to previous GM trucks. The 6.2-liter V8 idles aggressively at rest and roars impressively at full throttle as it thrusts the big vehicle forward with eye-opening authority. One unpleasant surprise: There's an auxiliary input jack for the rear audio system, but none for the front.
