GMC’s 2019 Sierra has finally been revealed. It boasts a first carbon fibre box, pro trailering tools, standard 22” wheels, and much more. Let’s take a closer look at the professional-grade pickup!
The 2019 Sierra
Whenever we’re talking about the Chevrolet Silverado or the GMC Sierra, one question always comes up. Why does GM sell the same truck under two names? Quite often, the models have been distinguished by little more than a badge and grille. If GM simply unified the two brands, they could boast much stronger sales. But, for the 2019 model year, with full redesigns, GM has promised that the two trucks will be markedly different.
And, at least ostensibly, GMC has delivered. The new Sierra is bigger, taller, and lighter. On the inside, that translates to best-in-class headroom and legroom. On the outside, it translates to a pretty impressive profile. The front-end is clean and imposing, aided by the sharp C headlights, elevated hood, and tall grille. It looks much
The Sierra will feature a choice of three powertrains. The first is a 3.0L Duramax turbodiesel inline-six. It’s good to see GM addressing customer support for diesel pickups, despite the consumer concern that have followed the illegal emissions cheating from Volkswagen, Jeep, and RAM. Additionally, there will be two V8s, a 5.3-litre and a 6.2-litre variety – just like in the previous generation. However, both will be more efficient thanks to the inclusion of Dynamic Fuel Management which replaces Active Fuel Management.
Dynamic Fuel Management
In the simplest terms, a small number of cylinders generate a small amount of power more efficiently than many cylinders. So, in low performance demand situations, GM’s Active Fuel Management shuts down half of the engine’s cylinders (a predesignated block) to save fuel. The technology had not been dramatically altered since 2004, so the advent of Dynamic Fuel Management is exciting news.
Dynamic Fuel Management is capable of shutting down any of seven cylinders at any given time as a live response to the demands. That sounds complicated, but it just means that your V8 can be reduced to single-cylinder function when you’re driving very slowly. While Active Fuel Management improved fuel economy by 5.5%-7.5%, Dynamic Fuel Management pushes those numbers to as high as 15%.
High Strength, Low Weight
But the flashier fuel-saving measure, is the construction. Ford has gone all-in on aluminum – and met significant resistance for it (largely from GM). Instead of following the lead, GM is using what it calls a “mixed materials approach.” GMC will make the Sierra’s swing panels (hood, liftgate, doors) out of aluminum. Fixed panels on the body will continue to use steel. Most impressively, GMC is introducing an optional carbon fibre pickup box. It’s the first in industry history and it’s 62 lbs lighter than the steel one it replaces.
The 2019 Sierra distances itself even further from the Silverado with a ton of incredible technology like the MultiPro Tailgate. But we’ll cover the best innovations in a separate post.
