A 5.0-liter V8 boasts best-in-class payload capacity of 3,270 pounds, and a 3.5-liter EcoBoost V6 tops the class with up to 13,200 pounds of towing capacity.
For best-in-class towing, the second-generation 3.5-liter EcoBoost V6 delivers 13,200 pounds of towing capacity, thanks to its 470 lb. -ft. of torque that beats all diesel- and gasoline-powered competitors, including V8 engines with almost twice its displacement. The latter number "beats all diesel- and gasoline-powered competitors" and helps to give the truck a best-in-class towing capacity of 13,200 pounds (5,987 kg).
Ever since Ford announced it would offer the 10-speed automatic transmission in every engine configuration for the redesigned 2018 Ford F-150, we have been champing at the bit to hear more. Its economy has nudged up, too, with Ford saying it'll do 2 mpg better in 4×2 configuration overall, while the 4×4 version gets a point improvement in the city and combined. The 2.7-liter offers the same 325 HP as before, but torque is up 25 lb-ft.to 400 lb-ft. Its EPA ratings improved to 17 mpg city, 23 mpg highway and 19 mpg combined. For 4×4 models, the engine produces 19 mpg city/24 mpg highway/21 mpg combined, up 1 mpg on all fronts. And once again, Ford gets to claim best-in-class, thanks to the 2.7-liter V6, which achieves 20 mpg city and 26 mpg highway in 2WD. 4×4 models are 1 mpg better all around with an EPA-estimated 16 mpg city/22 mpg highway/18 mpg combined. The F-150 Raptor's high-output 3.5-liter EcoBoost remains at 15 mpg city/18 mpg highway/16 mpg combined. With dual port and direct-injection technology, the 375-horsepower twin-turbo engine provides ideal low-end and peak engine performance for hauling heavy payloads and towing heavy trailers. In the middle of the range is the 5.0-liter V8 with 395 horsepower. The 3.3-liter V6 engine that will be returning about 19mpg in the city and 2mpg on the highway.
However, Ram also offers a 3.0-liter EcoDiesel V6 with 21 mpg city, 29 mpg highway and 24 mpg combined. Auto start-stop capability is now implemented no matter which engine is placed under the hood of the 2018 F-150. Fuel economy figures for that truck won't be out for a little while still.
