SAN ANTONIO — The revamped 2022 Toyota Tundra will boast a pair of new V-6 powertrains, including a hybrid, that offer improved mileage over the discontinued V-8 predecessor, plus a number of interior and technical refinements, including an improved infotainment system.

The next-generation full-size pickup equipped with a gasoline-powered, twin-turbo 3.5-liter V-6, named i-Force, is estimated by Toyota to get 20 mpg combined in 4×2 form, a 5-mpg improvement over the 2021 4×2 with a 5.7-liter V-8 engine. That moves it closer to comparable versions of the 2021 Ford-150 (22 mpg), Chevrolet Silverado (21 mpg) and Ram 1500 Classic (20 mpg). Toyota did not disclose the i-Force Max hybrid’s mileage; EPA fuel economy figures for the gasoline and hybrid models will be released later. No diesel version will be offered.

Toyota, which has dribbled out details about the truck since spring and formally introduced it last month during “Sunday Night Football” on NBC, released key specifications on Tuesday.

The Tundra will come in six trims: SR, SR5, Limited, Platinum, 1794 Edition and TRD Pro, each with its own distinct grille. Prices will be revealed near launch at the end of the year. Lisa Materazzo, Toyota Motor North America’s group vice president for marketing, told journalists gathered here that pricing will be “aggressive.”

Buyers can opt for either a 4×2 or 4×4; double cab or CrewMax configurations; and a 5.5-foot short bed, 6.5-foot standard bed or an 8.1-foot long bed.

Other improvements over the outgoing Tundra, which has been redesigned for the first time in 14 years, are in payload and towing capacity. The body is slightly taller and wider. A new 10-speed automatic transmission replaces a six-speed gearbox, contributing to the improvement in fuel economy.

The pickup will feature advanced LED lighting, a massive available two-row skylight and a much-improved interior with added standard safety systems.

Cosmetically, perhaps, the most notable change inside is Toyota’s new Audio Multimedia infotainment system. An 8-inch touch screen is standard; a massive 14-inch screen is optional.

Developed by the automaker’s Connected Technologies team, the system responds to voice commands quickly after the push of a button or the where one cabin’s occupants says, “Hey Toyota,” giving a pickup in the rugged full-size segment modern high-tech flair. Lexus’ variation of the new system, named Lexus Interface, will debut in the NX crossover.
