Drivers thinking of buying a 2014 Silverado or Sierra from GM don’t have to worry about the engines lacking power.

GM says, the 2014 Chevrolet Silverado 1500 and High Country and the GMC Sierra and Sierra Denali 1500, available this fall, are powered by a 6.2L V8 that produces an SAE-certified 420 horsepower (at 5600 rpm) and 460 lb.-ft. of torque (at 4100 rpm), the most power of any pickup engine and torque of any light-duty pickup truck engine.

GM also says that the 6.2L V8 available for Silverado LTZ and High Country and Sierra SLT and Denali models also delivers class-leading maximum available trailering capacity of 12,000 pounds when properly equipped.

“Power and towing capacity are fundamental capabilities for full-size pickups,” said Jeff Luke, General Motors executive chief engineer for full- and mid-size trucks. “The 2014 Silverado and Sierra deliver unmatched power and towing capability with a host of ingenious driver aids.”

Silverado and Sierra trucks equipped with the 4.3L V6 will have available towing ratings of up to 7,600 pounds, the highest for any base V6 in the segment, according to the GM. Silverado and Sierra trucks equipped with the 5.3L V8 and the max towing package, available later this year, will have towing ratings of up to 11,500 pounds when properly equipped.

GM says all three engines feature direct fuel injection, Active Fuel Management (cylinder deactivation) and continuously variable valve timing, a combination not found in competitor vehicles.
