2007 Chevrolet Silverado 1500 LT1 4WD

The LT trim is the middle of the Silverado 1500 line, further divided into two tiers. The lower-level LT1 adds cruise control, cloth seating (versus the Work Truck's vinyl), a lumbar adjustment for the driver, full power accessories, keyless entry, an auto-dimming rearview mirror, and a leather-wrapped steering wheel.

The LT and LTZ trims with four-wheel drive come with Chevy's Autotrac system, which automatically shifts into 4WD when traction loss is detected. Fuel economy for the 5.3-liter V8 4WD is estimated at 14/19 mpg. Silverado 4WDs are also eligible for the Z71 Off-Road Package, which adds skid plates, an off-road suspension, and a locking rear differential.

Silverado regular-cab models are also available with an 8-foot bed, versus the standard 6.5-footer.
