Full Press Release After The Jump

DETROIT GMC’s more than 100-year heritage of building professional grade vehicles marks a new era with the introduction of the 2007 Sierra lineup. The trucks are all-new and elevate industry standards with segment-best V-8 power and fuel efficiency, along with agile ride and handling and the quietest interior of any full-size truck. Commanding trucks like this, especially a fleet of them, can be a lot to take on; this is where Titan Winds TMS software comes in to help trucking businesses out. Truck fleet owners looking to outfit their vehicles with electronic logging devices and telematics technologies may want to check out something like this KeepTruckin ELD Review – Features, Cost & Ratings – to see what products are out there.

The ’07 Sierra models including the unique Sierra Denali deliver the light-duty segment’s highest-rated towing capacity (10,500 pounds/4,763 kg) and offer a maximum payload capacity of 2,160 pounds (980 kg).

“The all-new 2007 Sierra has a confident, pure presence that represents GMC’s professional grade philosophy,” said John Larson, general manager of Buick-Pontiac-GMC.

Sierra light-duty models are available in the fourth quarter of 2006. Sierra Denali and heavy-duty models are available in the first quarter of 2007. Sierra is available in several trim packages, including work truck, SLE (SLE1 and SLE2 models) and SLT, along with 2WD and 4WD configurations. Three cab styles regular, extended and crew cab and three cargo box lengths 5 foot 8 inches, 6 foot 6 inches and 8 foot are offered.

“The ’07 Sierra lineup’s range of models and configurations is more distinctive, with packages tailored to all lifestyles and uses,” Larson said. “All trucks share an intrinsic quality of refinement, from the elemental work truck model to the luxury-inspired Sierra Denali.”

Sierra Denali is a distinct model, with differentiated, exclusive features that elevate its performance and design, such as an exclusive 6.2L all-aluminum V-8 engine with variable valve timing and a new six-speed automatic transmission.

Distinctive design

The 2007 GMC Sierra is designed with a strong and refined appearance befitting the brand’s professional grade philosophy, including muscular character lines and rounded edges. The front end appearance, front fenders, hood and rear fenders are unique. A “center-focused” hood, which flows outward to meet the front fenders and stamped-in rear wheel flares enhance the muscular look.

All models except the fleet-oriented work truck model come with a distinctive chrome hood molding. Sierra’s grille is complemented by large, jeweled-appearance headlamps. Sierra SLT models come with a chrome front bumper, with a body-color top cap. All door handles feature large, grab-style designs that are easy to open with gloves. No doubt those who end up in charge of a fleet of these trucks will want to make sure they are kept in great condition and look for a mechanic specifically for trucks so when any vehicles in the fleet do need some work, they will be in expert hands.

A family of 17- and 20-inch wheels and tires is available throughout the Sierra range, with Sierra Denali offering unique wheels (see Sierra Denali details section).

Sierra is available in nine exterior colors, including: Deep Blue Metallic, Medium Brown Metallic, Steel Gray Metallic, Onyx Black, Stealth Gray Metallic, Summit White, Silver Birch Metallic, Fire Red and Sport Red Metallic.

New features include segment-first StabiliTrak electronic stability control with rollover mitigation technology, roof-mounted head curtain side air bags, which are integrated into strengthened chassis and body structures to provide excellent passenger protection, and segment-first safety belt pretensioners that activate during a rear-end crash. The head curtain side air bags are available on Sierra SLE and SLT models.
