First Look: GMC Sierra and its Unique ‘MultiPro’ Tailgate on GMC Sierra MultiPro Tailgate

In keeping with a bigger-is-better U.S. market that is aided by cheap fuel and cheap credit, the 2019 Sierra AT4 1500 is larger in almost every dimension not unlike many ‘Mericans.

This includes a longer wheelbase and longer crew cab body that offers about 3 inches more rear legroom than the previous model. Unfortunately, the prices – $36,595 to more than $62,000 – are larger too.

One good detail is the (marketing babble alert)MultiPro Tailgate* that has six functions and positions for loading, load-stopping, and the much needed pickup version of mountain climbing without ropes into the bed.

With size and complexity comes weight and diminished performance, of course. As a counter, an industry-first carbon fiber cargo-box is bolted to the steel frame rails. It’s said to increase durability and efficiency while offering best-in-class dent, scratch and corrosion resistance. No data or independent tests were offered as proof of this assertion.

Best-in-class cargo volume comes with Sierra Denali’s 5’ 8” box at 63 cubic feet of volume. Most of that volume was created by widening the maximum width of the bed floor nearly seven inches. (Let’s hope you never park next to one.)

All told, the Sierra can be as much as 360 pounds (163 kg) lighter than the previous model, because of a mixed materials approach, including – a salute to the breakthrough Ford F150 – aluminum for the doors, hood and tailgate, However, there’s  steel for the fenders, roof and standard cargo box. The fully boxed steel frame that is 88 pounds (40 kg) lighter than its predecessor, with 10% greater torsional rigidity. Changed front and rear suspensions have new, lightweight components. (Aluminum Ford F-150 Top IIHS Safety Pick, but Criticized, not for the First Time on Repair Costs, which could be Premature and Ford F-150 Aluminum Pickup Sheds 700 Pounds Late this Year)

Advanced technology items such as a Rear Camera Mirror are being pulled down from more expensive vehicles on the market – if you can refer to $32,000 – $85,000 GMC pickups as less expensive. Compared to the now prosaic inside rear-view mirror, this dual-mode looking glass functions either as a traditional mirror or as a camera screen. The camera mode helps to eliminate obstructions such as rear- seat passengers and head restraints while providing a wider, less clogged rear field of view.
