The third generation of the Sierra pickup 2500 HP showed up in 2007 as a 2008 model, and GMC built it in three cab versions.
With an increasing demand for full-size pickups and room for all family onboard, General Motors offered the Sierra with a four-door cab version named Crew Cab. Sure, it might be used as a workhorse for a crew during the week, but in the weekends, it was an excellent family companion pulling that full-size trailer behind without tearing a sweat. 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 Crew Cab offered an easy ingress and egress from the car thanks to its full-size rear doors.
Inside, the dashboard looked closer to an SUV than to a work truck, but its rounded instrument cluster covered a panel with more dials than a regular car. On the tall center stack, the carmaker installed a couple of cup-holders and a large storage compartment. In the back, the flat bench offered room for three with enough leg- and headroom for adults, not just for kids.
GMC offered the Sierra with a choice of two engines paired as standard to a 4-speed automatic gearbox. Unlike the rest of the 2500 HD range, the carmaker offered the Crew-Cab version with a hybrid power as well.
