All models have a revised grille and redesigned hood, plus lower base prices as part of a value-pricing strategy. The optional 6.6L Duramax turbodiesel engine has been re-engineered to deliver more horsepower and torque. A stronger cast-iron block improves durability, while a lower compression ratio allows more complete burning of the fuel to increase power and reduce oxides of nitrogen emissions. A revised variable-geometry turbocharger increases throttle response and provides on-demand exhaust braking. The engine can be mated to an optional 6-speed Allison automatic transmission. Other changes include larger glass area for the power side mirrors plus a manual extension feature to assist in trailer-tow applications and a combination antenna for OnStar and optional satellite radio systems.
