2007 Chevrolet Avalanche
Bob Plunkett

The Chevy Avalanche has been redesigned and re-engineered for 2007 and the new version is vastly superior to its predecessor. The new Avalanche rewards its driver with taut handling. It's well designed throughout with impressive attention to detail. The previous-generation Avalanche was good. This new one is better.

The Avalanche is and always has been one of a kind. It successfully combines the hauling capacity of a long-bed pickup with the comfort of a five-passenger sport utility vehicle. It switches between these roles using its ingenious Midgate, a removable rear bulkhead between the passenger compartment and the pickup bed. Along with a hard, tonneau-like bed cover, the Midgate allows the Avalanche to be configured as a Tahoe-sized sport utility with a short bed. Fold down the rear seats and open the Midgate and it's like a pickup with an enclosed eight-foot bed, capable of securing valuable gear from thieves or shielding drywall from weather. Remove the rear glass and the tonneau panels and it's a sporty, open-air truck capable of hauling an ATV.

For 2007, none of this practicality changes, including, for the most part, its workhorse capabilities. The Avalanche offers an 8,000-pound towing capacity, making it an excellent choice for towing an enclosed car trailer or a fairly big boat. It's as long as a Chevy Suburban and can haul a lot of stuff, with payloads over 1,300 pounds and a bed designed for abuse.

Handling and ride quality are greatly improved, thanks to updated underpinnings. The previous-generation Avalanche handled well for a truck its size, but this new one handles much better.

A major redesign gives the cab a more car-like look and feel, with a classier dash and more comfortable seats. Combined with better-integrated driver-assist and entertainment features, the creature comfort upgrades are as welcome as the modernized mechanicals. Also, the Midgate, removable rear window, tonneau covers and other features seem to snap together even better than before and everything appears to be of high quality.

Finally, there's the facelift. This cleaner, quieter, more mature look says as much as any of the other updates, upgrades and new technology about the vision Chevy has for its future. It's a vision with high promise. We like what we're seeing here. Model Lineup
The 2007 Chevy Avalanche comes in one configuration, a half-ton, full-size pickup with four doors, room for up to six passengers and outfitted with a unique, fold-down rear bulkhead accessing an enclosed bed.

Three engines are offered, two 5.3-liter V8s, one making 320 horsepower in the two-wheel drive version, another 310 horsepower in the four-wheel drive model, and a 355-hp, 6.0-liter V8 scheduled to appear later in the model run. The transmission is a four-speed automatic, mated to an electronic transfer case in four-wheel-drive models. The heavy-duty Avalanche 2500 has been discontinued and is no longer available.

The LS 2WD ($31,790) is the entry-level Avalanche, along with the LS 4WD ($34,790). Seats are cloth covered benches, front and rear; the front splits 40/20/40 with a six-way power driver's seat and manual recline on both driver and passenger seat, the rear 60/40. Standard features include dual-zone air conditioning, the usual array of powered utilities including the tailgate lock, multi-media stereo radio, leather-wrapped tilt steering wheel, front and rear seat carpeted floor mats, two auxiliary power outlets, ready-to-tow trailer setup and P265/70R17 all-season tires on aluminum wheels. Notable options include a stereo upgrade adding an in-dash, six-CD changer ($300); XM satellite radio with pre-paid, three-month trial subscription ($199); power adjustable pedals ($120) with rear park assist ($245); luggage rack ($195) and cross rails ($45); auto-lock rear differential ($295); and white-letter highlighted tires ($125). Also, but only on the LS, is a delete-option (-$600) soft cargo cover in place of the standard three-piece, hard cover.

The LT 2WD ($32,490) and 4WD ($35,490) feature an upgraded interior with cloth bucket seats, six-way power adjustments for the driver's seat, manual recline on both seats, a center console, and rear-seat audio controls with dual headphone jacks. Halogen fog lamps are standard. A front bench seat is a no-cost option. Options in addition to those for the LS include: automatic, dual-zone climate control ($195); DVD-based rear-seat entertainment system with remote and wireless headphones ($1295); touch-screen, DVD-based navigation system with voice recognition ($2250); Bose premium speaker system ($495); power, tilt-and-slide sunroof ($995); universal remote transmitter ($105); and P275/55R20 blackwall tires on polished aluminum wheels ($1795).

Option packages for the LT include 2LT ($2,040) with automatic climate control system, the universal remote, the six-CD stereo, leather upholstery, power adjustable pedals, rear parking assist and remote vehicle starter. In addition, a rear-view camera system ($250) is available with the 2LT package. The 3LT package ($3,650) includes 2LT plus 12-way power, heated front bucket seats with two-setting driver memory; outside mirrors with dip-to-park, integrated turn signals, driver-side auto-dim and ground courtesy lighting; the Bose premium speakers; and XM satellite radio. Rain-sensing windshield wipers ($95) and a heated wiper washer fluid system ($85) can be ordered with the 3LT package.

The LTZ 2WD ($39,225) and 4WD ($42,225) come standard with most of the equipment that's optional on the other two models. Also standard is a premium suspension package with variable shock damping and air-assisted rear load leveling. Power retractable running boards ($1,095) are optional. The luggage rack crossrails are optional, along with the rear-view camera system, the sunroof, the rear-seat entertainment system and the navigation system.

Safety features that come standard on all models include the required front-seat airbags and LATCH rear-seat child safety seat anchors. The OnStar crash-notification system is standard. Full-coverage, side-curtain airbags that protect against head injuries in side impacts and rollovers are optional ($350) on the LS and the LT, including the 2LT treatment, and standard on the 3LT and LTZ. Active safety features that come standard include antilock brakes, electronic stability control, all-speed traction control and tire-pressure monitors. Walkaround
The Chevy Avalanche is a truck, and it's a big truck. In fact, the Avalanche is just an inch shorter than a Chevy Suburban. (Okay, it's 1.1 inches shorter.) The Avalanche rides on the GMT900 platform, meaning it shares its basic structure with the Chevy Suburban, Tahoe, Silverado and other full-size GM pickups and SUVs. The new 2007 Avalanche doesn't look as massive the first-generation (2002-2006) models did, even when they were ordered without the side cladding. In practical terms, the new Avalanche is just as big as the previous-generation models. (To be exact, the new one is 0.4 inches shorter.)

The 2007 Avalanche features some significant styling and design changes, though many of the changes are subtle. A fresh face brightens the front end. Thick, horizontal lines emphasizing the substantial girth remain, but are now integrated well with the body-colored grille and headlight surrounds. Lighting elements share space in single units, replacing the previous model's bifurcated assemblages. A bold bow-tie icon graces the grille crossbar. A high-relief lower fascia houses tow hooks and tries to look like the leading edge of a skid plate (which, by the way, is not offered by the factory, even on the 4WD version).

The side aspect is mightily spruced up, with a faster, more laid-back windshield leading to smooth, gracefully sculpted flanks topped by understated, flush-mounted windows. Gaps between body panels are tight. Full-round door handles accommodate gloved hands. Squarish wheel wells look underfilled, even with the optional 20-inch wheels. Essential as the signature feature of the Avalanche is the angular, hard plastic bed cover with the flying buttresses arcing down from the roofline to the bed sidewalls; it's the only design cue that clashes with the sleeker look of the new model.

The tailgate presents a more traditional pickup look than that of the previous models. It's less stylized, with bumper and release assembly now painted body color. That assembly also now functions as a base for the optional rearview camera. Chevy says this can help a solo driver hitch up a trailer; we haven't tested this yet, but it could save a lot of trial and error. We have used the rearview camera for parallel parking and other maneuvers in tight quarters and can attest to its value. This system is not a gadget. It speeds parking and maneuvering and can help alert the driver to the presence of a child or adult behind the truck. The tailgate is now spring loaded to lighten its perceived weight, but it still seemed heavier than its countersprung counterparts on the Ford F-150 and the new 2007 Toyota Tundra. Interior
The new interior of the 2007 Avalanche breaks with Chevy tradition much more than the exterior does. The new cabin marks a watershed in ease of use, not to mention ease on the eye.

Following a pattern established in the new Tahoe and Suburban, the interior designers slashed several inches from the top of the dash, rounded it off and smoothed it out, effectively pushing it down and away from the front seat occupants. Everything about the dash and instrument cluster is leaner, cleaner, dare we say it, more like a car's. A large, round tachometer and matching speedometer dominate the gauge cluster, complemented by four smaller dials reporting information vital to the operation of a truck capable of hauling heavy loads or pulling large trailers or transporting as many as six occupants.

The new center stack houses controls for stereo and climate management, two power points, and buttons for optional features such as the power adjustable pedals. Models with bucket seats get a center console with a large, open storage bin outfitted with a removable, dual cup holder. Aft of this is an equally large, but not especially deep storage compartment beneath a padded, hinged cover that doubles as a center armrest. The glove box isn't as expansive as it looks when closed. Front door panels have hard-plastic, fixed map pockets with molded-in can holders.

The seats are new. The relocation of the shoulder belt anchor from the outboard side of the seatback to the B-pillar allowed a slimmer, lighter and more secure seat assembly, and we appreciated that. We thought the bucket seats could use more thigh support, however, and they felt more bench-like than sporty.

The rear seats offer adequate and decently contoured space for adults, even those a few inches taller than six feet. Rear seatbacks don't recline, nor do they fold all the way flat with the head restraints in place, unless, that is, the front seats are moved almost all the way forward on their tracks.

The fit and finish impressed us. Tolerances between panels were tight. The wood grain trim didn't quite pass the authenticity test, but it added at least a hint of upscale. The optional leather upholstery and other materials favored durability over luxury without looking or feeling cheap.

Outward visibility is about what's expected from a full-size pickup. The hood drops away fairly steeply from the base of the windshield. The flying buttresses hamper quick lane checks, although the large outside mirrors compensate somewhat. When deployed, the roof-mounted, rear seat video screen for the optional entertainment system pretty much fills the middle portion of the inside rearview mirror.

In all but one measure, those aforementioned five or six occupants enjoy as much if not more room in the '07 Avalanche as in the '06. Front seat hiproom, for instance, grows by more than two inches, rear seat headroom by more than an inch. Rear seat hiproom drops by an infinitesimal two-tenths of an inch. It's like sitting in the first two rows of a Chevy Tahoe. The new Avalanche also equals or marginally betters the interior dimensions of the most comparably configured competition, the Ford F-150 SuperCrew shortbed.

The midgate is what separates the Avalanche from other pickups. First, with the midgate and bed cover in place, you get a four-door truck with a huge, lockable trunk. Fold the seats down and the trunk gets even bigger. Lift off the bed covers, fold the seats back up, and it's a pickup with a short bed. Think of it as a Chevy Tahoe with a short pickup bed. Finally, fold those rear seats and the midgate and remove and stow the back window and bed cover, and it's transformed into an open-air hauler with room for all sizes and shapes of cargo, from regular-size sheets of plywood to a brace of off-road motorcycles or an ATV.

Folding the midgate but leaving the back window and bed cover in place provides 101 cubic feet of enclosed, mostly secure, contiguous storage space, about the equal of seven-plus car trunks. The bed measures 63.3 inches with the midgate in place, 97.6 inches with the midgate folded down. By comparison, an F-150 SuperCrew's shortbed is 67 inches long. The supporting structure for the bed cover is sturdy enough to support a a 250-pound man. This can be a useful feature. We've walked on the cover and found it quite stable. The cover incorporates two, lockable storage bins on each side just forward of the tailgate, but the height of the bed's walls make them hard to reach by anybody shorter than five-foot-eight. On the other hand, they are water tight and fitted with drains, making them usable as coolers. This last feature can make the Avalanche the center of activity at a tailgate party.

We found converting the Avalanche from SUV to pickup to be a fairly easy process once learned for the type of people who buy full-size pickups. But it does take some time, patience and even a little strength because the panels covering the bed weigh 20 pounds a piece and can be awkward to handle. It's best to leave them at home when not being used. Also, the rear glass panel must be carefully snapped into a holder when removed. Don't let your buddies do this for you. All of this takes a few moments of unhurried activity to perform. It's serious car stuff, sort of like putting up the top on an old convertible, but not as serious as trying to put the soft top back on an old Jeep. Driving Impressions
Chevy did more than merely re-skin the Avalanche for 2007. Substantive and substantial work under the hood and to the underpinnings has delivered a new Avalanche improved in virtually every respect.

Most remarkable is the upgraded ride and handling, with especial emphasis on the handling. A new design for the front suspension coupled with rack and pinion steering, replacing the somewhat archaic recirculating ball system Chevy has been using for decades, has transformed the Avalanche's directional stability and responsiveness to steering inputs. Fully boxed frame members increase stoutness without adding mass, giving the suspension a more solid base from which to manage ride dynamics. It all works.

Steering is more crisp than casual. Occupants suffer little head toss over moderate pavement heaves. Body lean in corners is much less than in last year's Avalanche. Firm brake pedal feel returned controlled stops, even when a green light at an intersection occasionally seemed to jump directly to red, compelling a hurried stomp on the pedal. At such times, a diving front end was the dominant suspension dynamic.

There's less wind buffeting in the open-air configuration than you'd expect. For this, credit those flying buttress-type, angular diagonals behind the cabin, which channel most of the bluster back to the rear out over the bed.

The Avalanche is a workhorse for routine hauling. The bed is designed to take abuse and offers a 1,355-pound payload rating.

The 2WD model offers an 8,000-pound towing capacity (200 pounds less than last year's model), while the 4WD model offers 7800 pounds. We haven't towed anything with the Avalanche yet but it feels extremely stable and we're confident it'll make an excellent tow vehicle.

The re-engineered, more powerful engines deliver adequate acceleration, very linear. This is a heavy truck and we wouldn't call it quick. The transmission changes gears smoothly, although kickdowns for merging onto freeways or overtaking slower traffic bordered on lackadaisical. Power is up 25 horsepower over last year's model.

The popular 5.3-liter V8 is rated 310 horsepower and 335 pound-feet of torque and gets an EPA-estimated 15/20 mpg City/Highway. It's mated to a four-speed automatic.

The only disappointment came in observed fuel economy improvements versus those promised by the engine's high-tech controller. One element of this computerization enables the engine to run on either regular gasoline or E85, a mixture of 85 percent ethanol and 15 percent gasoline, or any combination of the two. Another, the Active Fuel Management feature, electronically converts the V8 engine to a V4 under light load. Our test time with the new Avalanche did not include access to E85. But over the 300 miles we put on the Avalanche in the week we had it, miles split about evenly between interstate and local surface streets, we achieved 14.4 miles per gallon. And this was without ever towing anything or hauling anything heavier than a week's groceries. As for the Active Fuel Management feature, which electronically transforms the V8 to a V4 under light load, the telltale in the dash information display indicating V4 activation appeared only on downhill grades or while coasting, most often to a stop. This isn't all that surprising, actually, given that engine power drops by more than half in V4 mode. Summary
The 2007 Chevy Avalanche is new and improved in almost every way that matters. From ride and handling to looks and packaging, it's a refreshing upgrade and update of an innovative concept that delivers unmatched flexibility without sacrificing function.
