March 14, 2017—The new 2019 Chevrolet Silverado 1500 is rumored to have an aluminum body atop its steel frame, according to Car and Driver.

The 2019 Silverado model was spotted test driving in Torrance, Calif. According to the report, General Motors was trying to pull off a misdirection tactic by dressing it up as a competitor.

While the use of aluminum still has not been confirmed, General Motors did reveal that they would use a lightweight material to make the pickup lighter, said Auto World News.

The 2016 sales for the Silverado were down by 4.3 percent from 2015, to 574,876. This figure is in contract to the Ford F-series, which saw sales rise by 5.2 percent, to 820,799.

As for its powertrain, the new Silverado will likely come with a pair of base engines. The first will likely be an updated version of the truck's 4.3-liter V6 engine. The other will likely be a turbocharged four-cylinder engine which will boost fuel efficiency. These engines will probably come with an eight-speed automatic transmission. The Silverado 1500 will probably get a V8 engine as well.

The 2019 Chevrolet Silverado 1500 is set to debut at the 2018 Detroit Auto Show.
