Fresh from a complete makeover in 2007, the 2008 Chevrolet Suburban soldiers on with an improved family of V8 engines and GM's strongest full-size SUV architecture to date. The Suburban hauls more passengers and cargo than anything in its segment, a fact not overlooked by those who need such convenience or capability. Cousin to the comparably-redesigned GMC Yukon XL and Chevrolet's own Avalanche SUV/pickup, the Suburban is also related to the shorter full-size Tahoe sport-utility. As before, Suburbans come with two- or four-wheel drive, and in regular 1500 or heavy-duty 2500 models. Depending upon the model, a variety of V8 engines are available, from a 5.3-liter Flex-Fuel V8 on 1500 models to a 352-horsepower, 6.0-liter V8 on the 2500 versions.You'll Like This Car If...
If you're a fan of big passenger-carrying wagons, and can cope with the operating costs, SUVs don't get much bigger than a Suburban. Boat and trailer owners in particular gravitate toward Suburbans, which offer up to 8,100-pounds towing capacity (or 9,700 pounds for the two-wheel-drive 2500 series).You May Not Like This Car If...
Unless you really need this much passenger- and cargo-hauling capability, a smaller vehicle, such as the GMC Acadia, might be a better choiceespecially if gasoline prices resume their recent rise.What's Significant About This Car?
Chevy has made head-curtain side airbags standard on all models, while the 2500 models receive new 17-inch wheels, StabiliTrak stability control and six-speed automatic transmission.Driving It Driving Impressions
Refinement, though markedly improved, shines less brightly in Suburbans than in shorter-length GM trucks. With four-wheel drive and the 6.0-liter V8, the automatic transmission sometimes seems to shift a little abruptly, and there is noticeable engine noise under harder acceleration. However, ride comfort is considerably more appealing; it's pleasantly absorbent and cushiony on smooth surfaces and copes reasonably well with bumps. Acceleration is vigorous from a standstill, if less so to pass or merge. The Suburban feels more truck-like than smaller SUVs and, on the expressway, it behaves admirably.Favorite Features
Active Fuel Management Technology
Chevrolet is one of several automakers offering V8 engines that can automatically switch to four-cylinder operation as a fuel-saving measure, and it's a welcome feature. Considering the propensity of big SUVs to guzzle gasoline, every little bit of technology that reduces consumption is a bonus.
Power-operated Running Boards
Sure, they might tap you in the shin if you're standing too close, but the Suburban's optional power running boards are wide enough to really help passengers who might have trouble climbing aboard.
There is more passenger space and improved seating comfort compared to the last-generation 2006 Suburban, along with greater overall refinementincluding enclosing the "close-outs" around seat bottoms for a cleaner appearance. Rear-seat passengers get increased shoulder room, and the driver benefits from a lower instrument panel that helps increase front-seat space. Two-tone color schemes use softer, low-gloss materials for the instrument panel. The third-row seat is removable, and a power-release fold-and-tumble second-row seat is available.Exterior
At 222.4 inches overall on a 130-inch wheelbase, the Suburban is undeniably a biggie. With body-on-frame construction, it's clearly a truckthough fancier in appearance than many cargo haulers. Improved aerodynamics are credited to a more sleekly-angled windshield and tighter body-gap tolerances, while a bulging power-dome hood adds to visceral appeal. Prominent fenders have integrated wheel flares, and the lower fascia displays a skid-plate look to enhance the rugged aura. Standard 17-inch wheels can be replaced by 20-inchers.Notable Standard Equipment
Three trim levels are available: LS, LT and LTZ, with three sub-divisions of the LT level (LT1, LT2 and LT3), and with either two- or four-wheel drive. Standard LS equipment includes daytime running lights, head-curtain side airbags, GM's OnStar emergency and communications system, side steps, split-bench front seat, cloth upholstery, heated power mirrors and remote keyless entry. The LT2 adds automatic air conditioning, leather seats and a six-disc CD/MP3 changer. Additional equipment on the LTZ includes Autoride suspension, heated front- and second-row seats, power-release folding second-row seats, a power liftgate, limited-slip differential and 20-inch wheels. The LT3 and LTZ trim levels include power front seats, a Bose speaker system and XM Satellite Radio.Notable Optional Equipment
The Z71 Off-Road option includes larger recovery-hook openings, more prominent foglamps, platinum chrome grille trim and on-road/off-road tires on 18-inch wheels. Power articulated running boards automatically move downward and outward as the doors open. Ultrasonic Rear Parking Assist is available, or the optional rearview camera displays the view behind the vehicle. The optional DVD-based rear-seat entertainment system features an eight-inch screen and in-dash loading. Also optional is the 6.0-liter V8 engine and a touch-screen navigation system.Under the Hood
With two-wheel drive, the Suburban 1500 has a standard iron-block 5.3-liter V8 engine that produces 320 horsepower. Four-wheel-drive models get a standard all-aluminum V8 rated at 310 horsepower. A 366-horsepower, 6.0-liter all-aluminum V8 is optional. Suburban 2500 models contain an iron-block 6.0-liter V8 that generates 352 horsepower. All engines except those in the 2500 models operate with Active Fuel Management technology, and two of the 5.3-liter V8s are E85-compatible. Each Suburban uses a four-speed Hydra-Matic transmission.
