'19 Silverado may emerge as efficiency leader

DETROIT -- Industry-first engine technology, significant weight savings and a new inline-six diesel offering are among the enhancements General Motors is counting on to bolster the Chevrolet Silverado's position as the second-best-selling vehicle in America.The redesigned 2019 model, shown Saturday evening ahead of the Detroit auto show, is larger than current models yet as much as 450 pounds lighter. It features a longer wheelbase, more interior space and a new high-strength steel bed with increased cargo volume and an available power up-down tailgate that can be operated from the key fob, an interior button or by hand.The enhancements and weight reduction could help the 2019 Silverado stake a claim as the most efficient full-size pickup in the market when it arrives in dealer showrooms in fall.GM product boss Mark Reuss called the redesign a “massive undertaking” that resulted in a “very responsive” truck that’s larger, lighter and more durable than ever before.“We are confident that the Silverado will be the very best truck for every customer,” he said Saturday following the unveiling of the trucks here.GM will offer six powertrain combinations, including a 3.0-liter inline-six diesel and 5.3- and 6.2-liter V-8s with a technology called Dynamic Fuel Management that can shut off cylinders, in a variety of combinations, to optimize performance and fuel economy. It's expected to increase efficiency by as much as 21 percent, though GM didn't give details.“It’s revolutionary,” Reuss said of the industry-first technology. “It’s like nothing we’ve ever seen before in terms of how many cylinders you can have at any one time in any one different condition.” 2019 Chevy SilveradoInteriorUp to 8-in. touch screenIncreased front and rear roomConcealed rear-seat storage areasDesign/engineering3.9 in. longerUp to 450-lb. weight reductionNext-gen cylinder-cutoff technologyOptional 3.0-liter I-6 turbodieselAvailable 10-speed transmissionRedesigned suspension to improve steering/brakingPower tailgate, up and downSource: FCA US, GMThe diesel engine -- the first in a full-size Chevy pickup since the late 1990s -- and 6.2-liter V-8 will be mated to a 10-speed automatic transmission. GM didn't provide details of other transmission pairings or engines. Chevy currently offers a 4.3-liter V-6 as its base engine.The redesigned pickup will have six engine options. The base engine, Reuss said, could “quite possibly” be a new offering. He declined to comment on whether it will be a four-cylinder engine.On the diesel, he said: "I am really confident that we will have the best-performing diesel in the segment."Ford Motor Co. earlier this week announced that it expects its first diesel F-150, which goes on sale this year, to achieve a highway fuel economy rating of 30 mpg.The eight trim levels include two new Z71 Trailboss models and an RST, for Rally Sport Truck, trim. The models will be much more distinctive than the Silverado's current offerings, said Sandor Piszar, Chevrolet truck marketing director. "We wanted to make it easier for consumers and dealers to find the right truck for what they're looking for, and we've further refined that notion," he told Automotive News, adding that consumers and dealers can expect a "similar price walk" to the current pickups.
