The new 2007 GMC Sierra HD lineup has the segment-best gross combined weight rating of up to 18,500 pounds, and the segment-best trailer weight rating of 13,000 pounds--both important numbers considering their intended duty as heavy haulers and commercial rigs. And with extensive new noise-reduction measures, it has one of the quietest interiors among heavy-duty trucks.
Professional grade tool for work; durability; versatility; a plethora of choices.
The 2007 GMC Sierra lineup consists of the 1500, 2500HD, 3500HD, and the luxurious Denali. The 1500 is the half-ton pickup suitable for personal use, while the Denali gets its own 403-horsepower 6.2L aluminum V8 engine. In between lie the trucks designed for work upon which GMC has made their "Professional Grade" reputation.
Like many pickups today the 2500/3500HDs are available in a wide variety of configurations, all of which are available with either two- or four-wheel drive.
The Sierra 2500HD allows a combined passenger/cargo weight nearly 4,000 pounds depending on cab type, bed length, and drivetrain, while the 3500HD can handle up to 5,300 pounds when configured with dual rear wheels. This is the optimum selection to take advantage of the 3500HD's 13,000-pound towing capacity.
All GMC Sierras benefit from a brand-new interior for 2007. The handles and knobs are designed to be operated while wearing work gloves. Under-seat storage enhances utility, as does a cavernous double glove box.
Three cab styles are available (regular, extended, and crew cab) and three box configurations are available (standard, long, and Dually long). The extended cab has two rear-hinged, half doors that open 170 degrees and have fully opening windows. Crew cab models has four full-size doors and has space for six adults. Both the extended cab and crew cab have a newly designed rear seat bottom that handily folds up out of the way without the need of a release lever.
3500HD models come in two additional variants, identified by SRW (single rear wheels) or DRW (Double rear wheels, sometimes called Dually). The DRW models offer enhanced stability for those who routinely tow trailers near the upper end of capacity.
Most folks will get by just fine with the standard 6.0L gas V8 engine that uses variable valve timing to produce 353-horsepower and 373 ft-lbs of torque. It is backed up by the latest version of General Motors' Hydra-Matic, now with six speeds.
For those who need maximum grunt, a 6.6L diesel engine makes only slightly more horsepower (365), but its 660 ft-lbs of torque should be capable of doing just about any job. This torque-monster is backed up by a six-speed Allison automatic transmission.
Two suspensions are now offered on the HD trucks. In addition to a standard suspension, the optional Z71 suspension is aimed towards off-road use and includes skid plates along with other additional equipment.
GMC's HD series has a bolder appearance, especially in front, with a wider grille, domed hood, and broader fenders. The HD trucks boast entirely new running gear, with a ladder frame underneath and hydroformed front section, a structure designed for better crash protection, new recirculating-ball steering gear aimed at improving steering feel, and a strong four-wheel disc brake system with anti-lock. The brakes now have an integrated trailer brake controller.
Trims run the range in price and comfort. The WT (Work Truck) comes with an interior designed to stand up to rough duty. The SLE1 adds such niceties as cruise control, a CD player, power door locks, and a leather-wrapped steering wheel. The SLE2 upgrades to dual-zone climate control, six-way power seat controls, and steering-wheel mounted audio controls. Finally, the SLT adds a premium leather interior, 17-inch bright machined aluminum wheels, a six-disc CD changer, and even heated windshield wiper fluid.
Some of the more notable options include power-adjustable pedals, Ultrasonic Rear Parking Assist, a remote starting system, a rear-seat DVD entertainment system on crew cabs, an EZ Lift tailgate, and a power-sliding rear window on extended and crew cabs. A wide range of audio systems includes MP3- and DVD-compatible players, along with XM satellite radio.
The Sierra 2500HD and 3500HD are new for 2007. The professional grade truck has been given a complete makeover from frame to body parts, and the all-new interior works well as a mobile office as GMC continues to make great strides in truck livability. An 8.1L V8 is no longer available on the GM pickups.
