Gloucester City GMC
Four engines are now available for the Sierra. There are three gasoline units and a turbodiesel. The smallest of the quartet is an all-new, thoroughly modern 2.7-liter turbo-four producing 310 horsepower and 348 lb-ft of torque. The next gasoline engine is a 5.3-liter V8 developing 355 hp and 383 lb-ft of torque, and then there's the familiar 6.2-liter V8 that puts out 420 hp and 460 lb-ft of torque. The last of the four is another new powerplant in the shape of a 3.0-liter turbodiesel, and eight- and ten-speed automatic transmissions are available.
As well as regular, extended and crew cabs, four engines, two transmissions, rear and four-wheel drive, and three bed lengths, buyers also get those six different trim levels to choose between. Where the all-new 2019 GMC Sierra differs from many rivals is the impressive array of standard equipment it comes with even in entry level form. The base Sierra features power locks, air conditioning, an AM/FM audio system with Bluetooth audio streaming and a USB port, and even Apple CarPlay and Android Auto compatibility. The entry model also comes with vinyl floors, cloth upholstery, an unlined bed, hill start assist and the V6 engine with a six-speed automatic transmission, but available options include LED bed lights, cruise control and keyless entry.
The Sierra SLE is likely to be a more popular model because it adds extra USB ports, power mirrors, a lift-assisted tailgate, an eight-speed automatic transmission, a power driver seat, keyless ignition, remote start and more.
Off-road enthusiasts will love the AT4, with its two-inch suspension lift, two-speed transfer case, skid plates, locking rear differential and Rancho shocks. Those wanting genuine luxury have the positively opulent, range-topping Denali.
