Sierra's accessible Ecotec3 5.3l V8 motor offers the best V8 efficiency in any fullsize pickup4 at an EPA-assessed 16 MPG city and 23 MPG expressway (2wd).
The 4.3l V6 is evaluated at 285 HP and 305 lb-ft of torque, and has an EPA-assessed MPG 18 city/24 interstate (2wd).
The 6.2l V8 is the most effective motor in a LD pickup at 420 HP and 460 lb-ft of torque, the greatest trailer weight rating of up to 12,000 lbs5 is the most offered in a light obligation pickup when joined with the accessible max towing bundle. Sierra's Ecotec3 motors are combined with a 6-pace or 8-velocity programmed transmission and are focused around 50+ years of demonstrated little square execution.
Immediate Injection, Active Fuel Management and Variable Valve Timing innovations make each of those motors more compelling and more productive than ever.the GMC's headlights and grille are more neatly outlined than the Chevy's, and the general styling seems to have been pulled straight off of the butch Sierra All-Terrain HD idea from a couple of years prior. Each Sierra comes standard with a chrome grille encompass and projector-pillar headlights.
