2007 GMC Sierra Classic

When it comes to engines, Sierra can't be beat. Sierra 1500 Crew Cab gives you more standard horsepower than Ford or Dodge.** Sierra 1500 also delivers the best V8 fuel economy of any full-size pickup.† And Sierra 2500HD and 3500 also offer best-in-class diesel horsepower and torque.**

Sierra was the first full-size pickup to feature automatic transmissions with Tow/Haul mode, which adjusts the shift pattern to give you more performance when you need it most. It's included in every Sierra automatic, including the 6-speed Allison transmission that's available on 2500HD and 3500 models.

To help you retain steering control, even during hard braking on low-traction surfaces, every Sierra features 4-wheel anti-lock brakes and Dynamic Rear Proportioning.

For the ultimate in 4x4 convenience, check out Sierra's available Autotrac electronic transfer case. With Autotrac, all it takes to shift from 2WD to 4WD is the touch of a button on the instrument panel. Autotrac also features a handy AUTO setting that selects 2WD or 4WD automatically as the conditions require.

Sierra Hybrid's advanced powertrain features a rugged 295 hp Vortec 5.3L V8 integrated with a compact 14 kilowatt electric induction motor. The result? Fuel savings of up to 12 percent††.
