    Vehicle Overview

    After a century of experience in building hard-working vehicles, GMC can claim a top spot in the full-size heavy-duty pickup trucks, and the 3500HD Extended Cab was proof.

    The pickup-trucks have become more and more luxurious and focused on passengers’ comfort. But there was a select range of vehicles that offered more than just convenience. They were designed to carry heavy loads, pull trailers with equipment, and help the owner put bread and butter on the table. Unlike its siblings with four doors, the regular-cab version was designed mostly for work, while the Extended Cabs were the middle road where a small team of five could travel short distances for a job.

    GM built the 3500HD version for work, and it showed it. Its front fascia was tall, fitted with big squared headlights and corner-mounted turn-signals. Depending on the trim option, the front bumper was black, body-colored, or chromed. The Sierra 3500HD Extended cab offered two doors at the front and a set of rear-hinged ones in the back. Like its Regular Cab version, it featured a choice of short or long beds.

    Inside, GMC installed either a bench for three or two individual seats, depending on the trim levels. The WT (Work Truck – base model) featured rugged vinyl floor mats and stain-proof upholstery. The SLT, top trim-level, offered a higher comfort level with individual seats, wood-trims, and a sat-nav system. In the back, the carmaker placed a bench for up to three occupants.

    GMC claimed that the most demanded version was the diesel version with its 6.6-liter Duramax unit that came with enough torque to pull a house and, thanks to the engine braking system, it saved the brake pads. All engine versions sent their power to the rear or all four wheels.

        Vehicle Overview

        General Motors released the third generation of the Sierra pickup 2500 HD series in 2007 as a 2008 model year and offered it with a choice of three cabins.

        It was already common to see the large, heavy-duty pickups used for weekends in the mountains or pulling trailers with boats or motorhomes on the highway. Most of them were crew-cabs, with four doors and a full house inside. The single-cab mainly was a work truck, while the Extended Cab was somewhere in between. It was still good to carry a family to the mountains, as long as it was a family with small children on board. For the 2500 HD (heavy-duty), the American carmaker used a new platform, the T900, which replaced the T800 and offered better solutions and more powerful engines than its predecessor.

        Like its predecessor, the Sierra was available in a few body versions, starting with a chassis-cab and going up to the big crew-cab version. Its raked windshield at 57 degrees decreased the wind noise and the aerodynamic resistance, increasing the fuel efficiency. To add a more dynamic appearance, the Sierra featured flared wheel-arches. The Extended Cab version featured two doors for the front passengers and another pair of rear-hinged doors behind them.

        Inside, the GMC Sierra offered two or three seating positions, depending on the trim level and options. Like most of the pickups on the market, it provided a big dashboard with a steering-column mounted gear-selector for the automatic transmission. The rear seats were surprisingly good as long as the occupants were not very tall.

        GMC offered the Sierra with a choice of two engines paired as standard to a 4-speed automatic gearbox. It was available either as a 2WD or 4WD.
