2019 Chevrolet Silverado Gets a Diesel I6 Engine and More Aluminum
450 pounds lighter and more efficient
The has already been presented last year, but that didn’t stop GM from showing it yet again at the 2018 North American International Auto Show in Detroit. This time, it comes with two surprising twists. One is the more widespread usage of aluminum which should shed some 450 pounds of its weight. The other is a new Duramax diesel inline six mill which finally rounds up the the full-size pickup truck diesel trilogy. All three major American half-ton trucks will now feature an optional diesel engine since has also joined the oil-burning party.
Unlike the Ford F-150 which has been using full body aluminum structure for couple of years now, the 2019 Chevrolet Silverado only comes with aluminum hood, doors and tailgate. Most of the truck is still made out of steel, though, with difference being in material’s grade. Bed is made out of roll-formed high-strength steel. Same as the floor pan, while rear side panels are made out of regular steel. Pillars and the rest of the safety cage, however, are all made out of advanced high-strength steel, as pictured below.
As mentioned above, GM has still managed to shed some 450 pounds off of the final product. Despite not going all-aluminum on us at that. The most important thing is that their use of mixed materials means the bed remains a fully steel affair. And you’ll likely remember how they’ve bashed Ford’s aluminum bed in one of their from a while ago. And most buyers will surely find that power-operated tailgate handy.
But more surprising – and some would also say important upgrade – is the all-new 3.0L Duramax diesel inline six mill. Engine that will be tied to an also new 10-speed automatic transmission, and which should outperform its upcoming Ford F-150 diesel rival. Blue Oval’s half-tonner produces 250 hp and 440 lb-ft of torque, while likely returning up to 30 mpg on the highway. But that’s far from everything that GM has up its sleeve. They’ll also revamp the current V8 lineup consisting of 5.3L and 6.2L units. These will now feature an all-new fuel-saving technology that’s capable of turning off as much as seven cylinders. Precise specs, release date, and prices are yet to be disclosed.
