Ford Motor Co. revealed details for the 2017 F-150 Raptor, highlighting its 450 hp and 510 lb.-ft. of torque.

The Raptor's hp and torque are the result of an all-new 3.5L twin-turbo high-output EcoBoost engine, which is mated to an all-new Ford-built 10-speed transmission. This allows the 2017 Raptor to deliver a 21% improved average torque-to-weight ratio and a 23% improvement in EPA-rated combined fuel economy when compared with the previous generation Raptor, according to the automaker.

“Raptor was designed to be a no-compromise, off-road performance machine,” said Matt Tranter, Ford performance engineering supervisor. “That is why we made the switch from the cast-iron V-8 to the aluminum block, high-output GTDI V-6 EcoBoost engine that our team tuned to add 39 horsepower and 76 lb.-ft. of torque for today’s Raptor.”

EPA estimated fuel economy ratings for the 2017 F-150 Raptor are 15/18/16 mpg (city/hwy/comb). Actual mileage will vary.

The new Raptor is up to 500 pounds lighter than the 2014 model and will start at less than $50,000, according to the automaker.

The 2017 Raptor delivers more low-RPM torque and optimized power bands and shift points across all two-wheel drive and four-wheel drive modes thanks to the 10-speed transmission and torque-on-demand transfer case.

Key 3.5L EcoBoost engine improvements include a new twin direct and port-fuel injection strategy, stronger and lighter crank and valvetrain components, and a redesigned twin-turbocharger system with electronic wastegate.

The all-new standard 10-speed automatic transmission features Auto Start-Stop and an integrated electric pump that improves driving efficiency.

The transmission’s closer ratio between gears and Ford-patented hydraulic control system better optimize the power and torque curves of the new 3.5L high-output EcoBoost engine.

Raptor’s all-new adaptive shift algorithms monitor more than a dozen powertrain and driver control signals in real time. In addition, a high-speed, one-way clutch allows for non-sequential shifting.
