The 2018 GMC Sierra 1500 Double Cab is a prominent contender in the fullsize pickup truck segment competing primarily with the Ford F-150 SuperCab, the Ram 1500 Quad Cab, and the Toyota Tundra Double Cab. Prices start off at an MSRP of $32,730 with the base trim and reach all the way to the top SLT trim carrying an MSRP of $45,780, for a total of 3 trims being offered. With multiple powertrain and cab options available across multiple cab styles and trims, there is a Sierra for everyone. The double cab offers four powertrains and comes in a single bed length. The base engine is a 4.3L V6 engine mated to a six-speed automatic transmission, capable of making 285 horsepower and 305 lb-ft of torque. This engine is rated for a towing capacity of 7,100 pounds. Other engine options include a 5.3L V8 and a 6.2L V8 both of which come affixed to an 8-speed automatic transmission. The 5.3L V8 engine puts out 355 hp and 383 lb-ft of torque and can tow up to 11,100 lbs. The 6.2L V8 produces a stronger 420 hp and 460 lb-ft of torque and is rated to tow a higher 12,500 lbs. The GMC Sierra 1500 Double Cab only comes with a 6.7 ft. bed. All in all, the GMC Sierra 1500 Double Cab delivers an exciting package, both in terms of performance and looks. The rugged and masculine exteriors are offered in 10 attractive colors.
