The full-size Ford F-Series is the number one selling vehicle in the U.S. The light-duty F-150 pickup lots below the F-Series Super Duty pickups in the automaker’s lineup.
Not only is the Ford F-Series the number one selling truck for four decades, it’s also the best-selling vehicle in the U.S. for 35 years. For 2021, the refreshed F-150 gets a new 3.0-liter Power Stroke turbodiesel V-6 that has yet to be rated for power or fuel economy. The new engine, which will likely feature twin turbos, is backed by a 10-speed automatic transmission.
Ford also updated most of the F-150’s gasoline engines. The previous model’s base 3.5-liter V-6 has shrunk to 3.3 liter, but gains a new twin-injection system (port and direct). Power ratings are unchanged at 282 hp and 253 lb-ft of torque. The 3.3-liter is backed by a six-speed automatic transmission.
The new second-generation 2.7-liter EcoBoost V-6 also gains the twin-injection system, while the 5.0-liter Coyote V-8 gains new plasma-transferred wire arc spray-bore cylinder lining for reduced weight over the previous engine’s iron cylinder liners. Ford says the 2.7-liter EcoBoost and 5.0-liter V-8 make more power than before. The second-generation twin-injection 3.5-liter EcoBoost V-6, with 375 hp and 470 lb-ft, introduced in 2017 carries over. A 10-speed automatic backs the 2.7-liter EcoBoost, 5.0-liter, and 3.5-liter EcoBoost engines. All 2018 F-150 drivetrains feature standard automatic start/stop.
The refreshed 2021 Ford F-150 pickup has a five-star overall safety rating from the NHTSA (out of a possible five stars) and is considered a 2018 Top Safety Pick by the IIHS. That F-150, last year’s model, received a front crash prevention designation of basic for its optional Adaptive Cruise Control and Collision Warning with Brake Support. The 2021 F-150 features precollision assist with pedestrian detection, which first warns the driver and second brakes the vehicle to lessen impact, while the adaptive cruise control now features stop-and-go traffic-jam cruising.
