Enter GMC with a well-timed All Terrain X collection for the Sierra 1500. The truck analyzed here is a two-step march up from the base $48,465 Sierra 1500 4WD Crew Cab SLT, which beings just below the Sierra Denali in GMC’s order. The $2105 All Terrain collection contains a concoction of rigid- and soft-core enhances, an off-road mixture with Rancho bumps, a locking back differential, an eight-speed automatic transmission, 18-inch wheels, body-color bumpers, a spray-on bedliner, Bose audio, heated leather rooms, and an area console with wireless charging.
The $4315 X collection—accessible on Sierra SLT 4x4s in the crew cab, short-box body style as well as double-cab, grade-box form—kicks in more masculine gear, Goodyear Wrangler DuraTrac on-/off-road tires, black-finished wheels and mirrors, led lights and taillamps, side levels, a performance gas exhaust system that adds 10 horsepower for a whole of 365 hp, and a full set of latex floor mats. A bed mounted sport room touts your Sierra Club body in mega-red missives. Add a few more enhances—a $995 energy roof, GMC’s $495 Intellilink information and entertainment system with navigation system and a $275 trailer-brake controller reaches our truck’s $56,695 framework aculeu.
The immobile mixture doesn’t beat you to death when you ride on pavement, the grade 5.3-liter V-8 is all but quiet at work, and the eight-speed automatic transmission come into act for 2015 and now accessible with the small Sierra V-8—reorderings wheels with the ability of a vegas blackjack merchant. This transmission offers trailer-tow and manual translation methods, allowing you to hold your chosen ratio up to the motor’s fuel limit. The perfection GMC has put into this truck is what makes it famous with well-heeled consumers desiring a truck with a beamy extent of on-road, off-road, pulling and towing abilities.
This is an enormous truck, and its 12-foot wheelbase and 47-foot turning ellipse convey it takes intending and practice to enter a grade parking spot. Every journey to the driver’s seat is a two-step rise, and the 35-inch-high gate is annoyingly high for performing average truck work such as filling filth bikes, home-improvement substances. During our 1000-mile drive, which referred borderline pulling and off-roading and no towing, we totalled 19 mpg. That’s decent for a follower 5688-pound automobile. One unfamiliarity is that lightweight, less extravagant Sierra 4x4s supplied with GMC’s six-speed automatic transmission outscore the eight-speed’s 15/21 mpg municipality/freeway EPA appraisals by 1 mpg each. While our Sierra’s 19-mpg spied fuel system beat two Ford F-150 trucks by 3 mpg, this GMC fell behind in practically every other experiment.
The run to 60 mph in 6.6 seconds is 0.3 second sedate than the 385-hp F-150 V-8 and 0.8 second sedate than the 375-hp EcoBoost V-6. Calcite that up to the Fords’ aluminum compartment and bed building, which gives them a 255-to-468-pound weight merit. The Sierra’s off-road latex hurt it in friction try-outs, where it needed more than 200 feet to stop from 70 mph (versus 179 to 187 feet for preceding four-by-four GMCs without the off-road case and tires). It also attained only 0.70 g of side adhesion on the skidpad, versus the F-150 V-8’s 0.75 g and the 0.77 g that its GMC relatives. The GMC’s freeway cruising sound stage is four decibels high than the Ford’s and two decibels big than with average all-season tires.
Fortunately, there is recompense for these performance disadvantages. This Sierra is a good looks with borderline chromium breaking its black out message. The 3.5-inch-high GMC missives in the black chromium opening are quite hard-hitting at rubbing left-lane idlers out of the path. The X collection’s few tasteless bits live discreetly in the led lamps, transport seeds, and Sierra All Terrain emblems. One flight of aureate is the double-tube bed embellishment, a visual organism to the Chevrolet Avalanche and the Cadillac Escalade EXT. This truck is too beamy to slip between trees and rocks. There are defender bases under the motor and movement case, but the fuel tank, front breezed barrier, spare tire and side levels are assailable to assault from the dark side.
Inside, this high Sierra is a version of perfect sensation. The three-adults-beamy back seat, a vanishing attribute in the vehicle world, beings here in cozy brightness. elevating the split bottom dampers opens space to obtain populating wheel, food refrigerators, and having tool galore. The red-stitched leather seat trim has side bolsters expressed with a credible use of twisted carbon material. The ignition still requires a key, but the compartment is otherwise well occupied with modern features. The front rooms are heated, and the pedals are adaptable. There are enough AC, DC, USB, and wireless charging options.
The area console and gloveboxes are commodious enough to aid an mobile enterprises. The 8.0-inch touchscreen is accordant with both Apple CarPlay and Android Auto. The slope of six analog devices will overwhelm classic-gauge fans, although a 140 mph meter in an automobile led at 98 mph seems silly. There’s an uncomplicated-to-use inclinometer in the driver’s agglomeration to note down pitch, spin and steering angles. One mistake is that the compartment lacks high-stage cooling holes for back inhabitants.
It’s no uncomplicated accomplishment to attract customers with a conventional truck while the multitude of crossovers offers fanciful mixtures to facility and pulling needs.
