Since the F series was redesigned in 2014 and given an aluminum body, Ford has added features nearly every model year, including a 10-speed transmission, a Raptor performance variant and swankier trims.
Spring will mark the first time in the F-150's storied history that it is available with a diesel, though performance details have not been released.
Later in the year, Ford will begin building Ranger midsize pickups in the U.S. for the first time since 2011, competing with the Toyota Tacoma, Nissan Frontier, Honda Ridgeline, Chevrolet Colorado and GMC Canyon.
Overall, Ford expects to sell just shy of 900,000 F-series trucks in 2017, not far off its record of nearly 940,000 in 2004.
"Certainly, there will be activity," said Todd Eckert, Ford's truck marketing manager. "But at the same time ... we really feel like we have an outstanding lineup to be competitive like we have been. That's what leaders do, and we're very confident in our product going forward."
Eckert said Ford will try to stay disciplined on incentives as Ram and Chevy likely put more cash on the hood to help move old models off dealer lots.
"Affordability continues to be very important, but we continue to feel very strong about our product and it fitting the needs of our customers, and that's how we'll continue to go to market," Eckert said.
FCA will reveal the details of its redesigned Ram 1500 at the Detroit auto show and likely will begin producing it the same week. Spy photographers caught much of the Ram 1500's new styling after a strong breeze blew the cover off a preproduction model this fall, revealing many secrets.
Under the hood, the next-generation Ram will have upgraded engines, complete with a 48-volt mild-hybrid belt-start generator system to improve fuel economy, as well as improved suspension systems.
It's also expected to shed weight from current versions, have a larger crew cab and come with the latest version of FCA's Uconnect infotainment system to go with a reworked interior.
FCA will continue to produce its current-generation DS Ram 1500 for at least a year while production of the new DT ramps up at a retooled plant in Sterling Heights, Mich., in suburban Detroit. The move should enable Ram to produce record numbers of pickups, with the current version packing the lower end of the trim and price spectrum.
In the fourth quarter of 2018, about the time the next-generation Silverado and Sierra are hitting the market, FCA will start building the Scrambler, a Wrangler-based pickup. The Scrambler will feature a midsize pickup bed attached to a four-door cabin similar to the 2018 Wrangler Unlimited. It also will carry the Wrangler's off-road suspension system.
Largely because of the Jeep badge, FCA expects to be able to sell the Scrambler at a substantial premium compared with competitors in the medium pickup segment.
