But apart from some exclusive features and some very different styling, there is not much difference between Silverado and Sierra, inside or below. All the impressive improvements we have seen for the 2019 Silverado also implement Sierra – the new, fully-framed frame; The mixture of optimized lighter materials in the body, the bed and the chassis; all six of the drives the smooth new trailer app; and much more.
Given how thorough we have talked about technical improvements for the new Silverado in the truck's review, we will not enter them for a long time, but you can read about them here. It's enough to say that GM spent a lot of development money on the systems and components that make their trucks better and make them easier to own and use – but GM just had a few goodies for GMC Sierra.
How It Works
GMC brought media to pinewood hills in Newfoundland, an external population The Canadian province is full of amazing scenery (and endless ways to prepare cod). Our route in the new Sierra covered a variety of terrain, from smooth, slow roads, scattered with sporadic potholes to high-speed highways. I sampled two of Sierra trim levels – the Middle SLT equipped with the 5.3-liter V-8 engine and an eight-speed automatic transmission, and Denali top number Denali that included the tough 6.2-liter V-8 and 10-speed gearbox.
Both models impressed the road, with much sharper control than in previous trucks. Directional stability is improved more vigorously than the previous generation truck, which is also body control – it's very little or dive when changing directions on a winding road or roundabout on a freeway on the ramp. The steering noise can also be adjusted: Just twist the knob is on the top left of the dashboard in Sport mode, and both effort and feedback increase. The gas response and transfer points also adjust to a more sporty nature, and in the Denali case, the electronic suspension also adjusts the damping for a firmer ride. The brake problem and performance are nothing short of outstanding – the pedal operates with an excellent start and continues to build progressive pressure throughout the journey, giving the driver a feeling of confidence and solidity.
But driving quality is mixed depending on the version you're trying – SLT with its smaller 18-inch wheels, higher tire sidewalls and non-adjustable suspension are actually more evenly tuned than Denali despite the latest trim level Adaptive Ride Control suspension and shock absorbers. Remember, this is not the fancy Magnetic Ride Control system we've seen on GM's SUVs like GMC Yukon, Chevrolet Tahoe or Cadillac Escalade, but another electronically adjustable system. It seems counter-intuitive that the cheaper SLT will have a more luxurious trip than the big belly Denali, but the seat-of-the-pants-o-meter does not lie: I prefer to drive SLT to Denali in some cases broken pavement we met.
Two of the six possible fuels
The difference in propulsion is also quite shocking because it does not seem to be much of a performance difference between V-8 engines when you have an empty truck. 5.3-liter V-8 in SLT was slim, smooth and never missing too shallow. It makes 355 horsepower and 383 pounds of torque, and it is paired with an eight-speed automatic transmission that drives all four wheels through an optional low-range four-wheel, four-wheel drive. This is also standard Denali drive, but you can choose something bigger if you want: 6.2-liter V-8 pump out 420 hp and 460 pound-foot torque. It is paired with a 10-speed automatic transmission and drives all four wheels back through an optional four-wheel drive system (although it should be noted that you can also choose 6.2-liter V-8 in SLT trim if you choose). Both of these engines have active fuel management and automatic shutdown to optimize gas mileage, and both systems seem quite discreet. However, automatic shutdown can be disabled, unlike other GM vehicles.
Throw a load into the truck's bed or connect a trailer and things slippery, natural. We loaded the 6.2 liter Denali bed with what I estimated to be about 500 pounds of equipment (lobster pots, a jackal, a cooler, different logs and boards) and Sierra did not have a blow. Even more impressive, a drag demonstration involving four road vehicles on a flatbed trailer of about 5,000 pounds, was equally uneven, with the big V-8 handling the well-built trailer without any problems or drama. 19659005] GMC says that the goal of creating the new truck was not to go for "best-in-class" tire ratings because research showed that customers rarely hit more than 5000 pounds with their trucks. Instead, the GMC Sierra 1500 optimized to be the easiest truck to set up for towing instead of hunting for an advertising number that does not have much real tools. We could not pull the less 5.3 liter engine, but we will in the coming months, so stay tuned for a more thorough drag variation in the not too distant future. But if towing or hauling is not something you do often, you'll hide more money from the 6.2-liter engine as an expense you just do not have to touch – 5.3-liter engine is perfectly acceptable on your own.
