First Ford F-150 Diesel

An entirely new 250-hp. V-6 diesel is being offered on 2018 F-150s.

Starting this spring you can take delivery on the first ever Ford F-150 that runs on a diesel. Turning out a best-in-class 250 hp. and 440 foot-pounds of torque, the 3-liter V-6 diesel is an entirely new engine but is based on the engineering that went into the creation of Ford’s 6.7-liter V-8 Power Stroke diesel, a mainstay power plant in that company’s Super Duty (F-250 and larger) line. 

“The more you tow and the longer you haul, the more you’ll appreciate its class-leading towing and payload capacity and how efficient it is at the pump,” says Ford’s Dave Filipe.

The V-6 diesel features the same compacted-graphite iron block material construction and forged-steel crank utlitized in Ford gas-powered 2.7-liter EcoBoost engines. But the V-6 diesel gets a variable-geometry turbocharger and common-rail fuel injection system that operates at 29,000 psi.

Ford engineers equipped the engine with a premium mechanical engine-driven fan and dual radiator shutters for improved high-temperature, high-altitude performance. “The viscous-controlled mechanical fan has the capacity to move much more air across the radiator and intercooler in extreme conditions,” explains Ford engineer David Ives.

In moderate driving and towing conditions, the engine control system backs off the fan load through a viscous coupler, closing down the two radiator shutters for improved aerodynamic efficiency and reduced parasitic engine loss.

The diesel is coupled with Ford’s standard SelectShift 10-speed automatic. That transmission can nonsequentially select the right gear ratio based on need.

The V-6 diesel is available for placement in both 4×2 and 4×4 F-150 pickups. Customers can choose this engine option with the Lariat, King Ranch, or Platinum styling packages as well as in SuperCrew trucks with either a 5.5- or 6.5-foot bed configuration.

Ford also recently announced it was tweaking the powertrain line for the entire F-150 truck line. For example, a new direct-injected 3.3-liter V-6 engine replaces the previous 3.5-liter V-6. That engine is expected to produce the same 282 hp. and 253 lb-ft of torque as the previous engine but consume less fuel.

The 2.7-liter EcoBoost V-6 was modified as well and is being replaced by a second-generation version with port- and direct-injection technology. The previous 2.7-liter engine was direct injection only.

The 3.5-liter EcoBoost V-6 continues for 2018, and the 5.0-liter V-8 is revised, with improvements in horsepower and torque expected. Ford has not yet released specific performance numbers for these engines. The company is saying that both EcoBoost V-6s and the V-8 will be paired with the 10-speed automatic transmission.
