And while both Chevrolet and GMC brands share the essential structure and engines and mechanical components for the General Motors truck, for the first time the GMC edition looks and feels different to establish a unique character and upscale style. A flashy chrome bumper underscores the prow, flanked by bulging front fenders and a shapely multi-tiered hood that rises to meet the new rake of a windshield. In back, truck beds measure bigger than before, for either Wideside or Sportside body styles. These redesigned boxes can accommodate multiple arrangements of cargo loads, too, with built-in slots and ledges on side panels to insert dividers to section the space or stack loads in tiers. The passenger cabin, as either regular size or an extended version with rear space for riders or gear, shows noteworthy improvements in function and comfort and room.
Bucket seats are also available.
On the extended cab, bench or buckets stand in front of a back bench with a wide bottom cushion and padded back tilted for comfort. Seat-mounted seatbelts show up in the back seat, and a third door on the left provides easy entry. In the power department, Sierra presents five engine options, including a thrifty six, three powerful V8s or a turbo-diesel workhorse. It's standard on Sierra regular cab. The three Vortec V8s, smaller in size but more powerful than previous V8s by GM, begin with a 4.8-liter plant pumping 255 hp.
