2007 Chevrolet Suburban 1500 LTZ 4WD
Highs: Plentiful power, quiet operation, smooth ride, big appetite for big jobs.
Lows: Big appetite for fuel, increased abilities are offset by decreasing relevance.

Content: Towing goes from 8000 pounds for 4WD 1500-series models such as our test vehicle to 9700 pounds for a 2WD 2500-series. There are essentially two V-8s—a pair of 5.3-liters, one of them iron block, the other all aluminum—and two 6.0-liters, ditto, with variable valve timing on the aluminum version, a $1095 option included in our tester.

Like GM's smaller (comparatively) full-size utes, the Suburban has been extensively revised for 2007, starting with the new GMT900 truck chassis. This firm foundation, plus a new coil-spring front suspension and new rack-and-pinion steering, yields distinctly more decisive responses. Improved dynamics, including stronger braking, are augmented by a raft of active and passive standard safety features, plus the option of four-wheel drive. Inside, this truck has a more upscale look, especially in our loaded LTZ (a package that adds more than $8000), and of course interior volume rivals that of a good many Tokyo apartments. Lows: Big appetite for fuel, increased abilities are offset by decreasing relevance. All in all, it's a better Suburban, and still the big boy to beat. But the future is full of question marks.
