We recently borrowed an '07 Chevrolet Avalanche to be the workhorse for a week of suspension testing on other Chevys. We had originally asked for a new Chevy truck to haul all the equipment, tires, camera gear, and spare parts, but when GM told us they only had an '07 Avalanche available, we quickly pursed our lips and said thank you very much; beggars can't be choosers.
The last Avalanche was not overly impressive in stock form, and the looks never really did grow on us, so we weren't expecting more than a four-wheel-drive taxi for our crew. At least it would be a first-time drive and we'd probably still be able to take two-thirds of our gear, and it would have four seats for passenger-carrying duty during our testing program.
We were caught off guard by an all-new body design that flowed excellently with the Avalanche's angled pillars and SUT configuration. The 20-inch wheels were not big attractions for us, but we could quickly overlook those when checking out the startlingly striking sheetmetal emblazoned in a Sunburst Orange Ii Metallic paint coat. We just called it burnt orange.
The body looked pretty good, but we knew it was going to handle like a walrus on rollerskates; it was on a Suburban chassis and that's just too much weight to really have any fun in corners, much less off road.
Danged if we weren't wrong there too. Once we hopped in the super-plush next level of Chevy luxury interior and were absorbed into the front seats, we gave a flick of the key to start what we found to be a torquey and strong engine that was perhaps a bit too burdened by the Avalanche's considerable weight. The steering system and steering wheel itself have a very nice feel about them as we took off from the truck yard, but we'd see what this thing felt like in a hard turn. We threw the wheel to the side to see how much lean this tanker had. The surprise that came from the staff members who drove this Avalanche at how well it handled can only be taken as an amazing achievement on Chevy's part. The tire package had a wide foot and this new Avalanche was squatting on the ground, but the lack of lean and the ease of steering through winding roads have to be majorly attributed to an excellently tuned suspension package. Chevy definitely got the shock valving right with this ride.
So would we give this thing a thumbs up? You bet. There were a couple of minor things we didn't like, and we'd have to yank off those 20s and see about some more aggressive tires, but this new Avy really was a blast to have around for a week. Plus, the automatic back-up camera that projects on the central control monitor let us back around the entire parking lot without looking up even once (yes, we shouldn't have been doing that).
 Chevrolet claims 10 1/2-inch...  Chevrolet claims 10 1/2-inch minimum clearance in the frontend; we'd swear there was less than that. We're not disputing it, because we didn't actually measure it at every point, but we're guessing the front bumper valence might be torn off on something lower than even 10 1/2 inches. |  We liked the middle-flow-through...  We liked the middle-flow-through console, but wondered why there was not a console-mounted transmission shifter instead of a column-shifter. What really drew most of our attention in the interior was the center control dash monitor. In reverse, a rear-mounted camera lights up a very clear image on the monitor, even during nighttime backings. But the GPS and radio controls also share this monitor, and we may just be stubby-fingered wrenchers, but we don't think the GPS and radio were user-friendly. |  One thing we definitely did...  One thing we definitely did not like was trying to turn on the headlights and grabbing the exact same style knob, just to the right of the headlight knob. The problem? That is the 4WD engagement, and we were trying to turn it to 4-low (or 4 "arrow-down" on the knob) on the freeway when trying to turn on our headlights. Chevrolet luckily puts electronic lockouts prohibiting such operations as engaging 4-low at 60 mph, but we still don't like it. What, they couldn't figure out a different style switch for 4WD and headlights?! At least put 'em on different sides of the steering wheel. |
 Though the rear end has been...  Though the rear end has been redesigned and features multiple back-up sensors embedded into the rear bumper, the cargo area looks much like a carryover from the previous Avalanche. In fact we bet that the top panels that cover the cargo bed are identical to the previous ones in dimensions. |  For now, the drivetrain package...  For now, the drivetrain package has remained unchanged, with a 5.3L Vortec engine backed by a 4L60E transmission. We noticed that the battery was moved from the standard driver-side front location to the back corner of the passenger side of the engine compartment, even though the original battery tray was still there. We're curious why they moved it, and we appreciate that they left the unfilled tray so it would be easy to mount dual batteries. |  |
