However at the least it seems to be the half because it trudges up this uncharacteristically verdant mountain with San Diego within the distance to the north and Mexico to the south. Its particular, dechromed AT4 grille has a purposeful look, however tastefully lacks the present-off machismo of Ford and Ram’s off-roading fashions. The purple tow hooks are a pleasant contact and the darkish-accented 20-inch wheels wrapped in all-terrain rubber are simply the correct size beneath a suspension that’s raised an additional 2 inches from each different Sierra.
That may be one of many key parts that differentiates the AT4 because the Sierra’s off-roading mannequin – GMC’s reply to the Chevy Silverado’s Path Boss trims. The truth is, their mechanical enhancements are similar. In addition to the two-inch raise, the suspension features off-street-tuned Rancho monotube shocks. There’s additionally a locking rear differential, a two-velocity switch case, skid plates and people tow hooks.
The 5.three-liter V8 with Dynamic Gasoline Administration is equally standard, however in contrast to the Silverado Path Boss, the Sierra AT4 gives the 6.2-liter V8 good for 420 horsepower and 460 pound-ft of torque as a roughly $2,500 choice. That is the engine we have now and it delivers the anticipated punch, full with a satisfyingly snarling exhaust observe. Nevertheless, as noticed in again-to-again drives with these two obtainable engines through the Silverado launch, the 6.2 definitely is not mandatory. The 5.three-liter is critically succesful and the larger engine is essentially for many who need to have the most important quantity attainable emblazoned on the fender. It is overkill, which on this specific surroundings, is becoming.
In addition to the out there engine improve, the AT4 additionally goes past its Path Boss counterpart by dipping into the Sierra Denali’s device field. Its MultiPro tailgate is standard gear, permitting for six totally different configurations, probably the most notable of which embrace a way of extra simply reaching into the mattress and a drop-down step that eases entry into the mattress. GMC’s appreciable touting of that final aspect is rife with hypocrisy given GM ads that mocked Ford’s comparable feature.
MultiPro admittedly has higher performance, together with an extra improve that embeds inside it a pair of audio system, rudimentary audio controls, and USB and aux inputs. It is sourced from marine purposes and appears prefer it. Sound high quality is suitable, if a bit tinny, however for tailgating functions, it might be a pleasant addition. Particularly because the mattress’s standard 120V energy outlet and that aux jack would allow you to plug in a TV again there, whereas GMC’s standard 4G LTE WiFi makes it potential to stream stay TV via one thing like YouTubeTV. Your tailgate social gathering might now feature the pre-recreation present.
One other Denali mattress feature is the non-compulsory carbon fiber CarbonPro mattress. GMC says it presents best-in-class dent, scratch and corrosion resistance. Our AT4 did not have it, however then we additionally forgot our rusty anchor at house. A test for an additional day, maybe.
The Denali’s mattress feature content material ought to be a clue that the AT4 (base price $fifty two,295) is just obtainable as an higher trim degree – the Path Boss gives base Customized and improve LT variations. Though MultiPro and CarbonPro are shared with Denali (together with heated and ventilated entrance bucket seats), the remainder of AT4’s standard features are literally in keeping with the decrease SLT trim degree. The Denali’s different extras – standard accident avoidance tech, Bose audio system, built-in navigation system, wi-fi smartphone charging and eight-inch gauge cluster show – are choices. You additionally get a vaguely carbon fiberish trim on the middle console and doorways versus the Denali’s vaguely woodish trim, however as each are plastic, does it actually matter? The Sierra cabin’s high quality and design proceed to underwhelm, particularly in an higher trim like this.
On the street, the AT4’s additional peak does not negate the brand new Sierra’s surprisingly lithe really feel. Perhaps “lithe” is just too robust a time period, however comparatively talking for a full-size truck, it modifications path with poise and does not overwhelm. A moderately small steering wheel helps on this regard, as does the improved rack it is related to for 2019.
Experience high quality can also be simply positive given the suspension’s off-street mission. Maybe the Ram 1500 and its coil spring suspension can be clearly cushier when pushed again-to-again, however in a vacuum at the very least, San Diego County’s much less-than-good roads did not floor any tiresome conduct. The Denali’s magnetically managed adjustable dampers can be higher nonetheless, however you additionally should not draw back from the AT4 due to them.
And actually, the AT4 must be thought-about an alternative choice to Denali. GMC definitely appears to think so, as it’s spreading the AT4 trim all through its lineup of trucks and SUVs to offer clients with a special taste of premium trim degree. As an alternative of fanciness and chrome, you get fanciness and ruggedness. Already, it is an strategy that is working. The Sierra AT4 has confirmed widespread amongst 2019 Sierra clients, staying on vendor tons solely 15 days on common earlier than being bought (a relatively very brief time).
Are these consumers more likely to benefit from the additional off-street potential? Historical past and market tendencies would point out in any other case (how typically do you see soiled Jeep Trailhawk fashions?), however ought to they struggle, we will at the least affirm the AT4 can deal with extra critical terrain. Later, GMC arrange a extra hardcore off-street problem with a steep rocky hill that really challenged the 4-wheel-drive and additional floor clearance. Not surprisingly, it handed with flying colours.
Probably the most spectacular take-away was truly the a number of cameras included within the AT4’s Know-how package deal, particularly the one in entrance, that permits you to successfully see by way of the monolithic hood, and efficiently navigate your self round in any other case hidden impediments. With out it, a slightly nasty boulder would’ve taken a piece out of that particular AT4 grille. There’s additionally an off-street inclinometer that exhibits the truck’s present tilt and entrance tire angle within the gauge cluster and, in that case outfitted, the large shade head-up show.
If something, know-how like which will truly encourage those that buy the AT4 principally for its type to attempt their arms at the kind of factor the truck is meant for within the first place. Hopefully they do, as a result of overkill can get awfully boring.
