A 2017 Ford F-150 Raptor prototype has successfully completed more than 1,000 miles (1609 km) of testing in the southwestern United States.

As part of the testing regimen, the truck was subjected to a 66-mile (106 km) desert trail which had "fast sandy washes, deep-rutted silt beds, steep climbs in deep sand, and slow meticulous crawls through tight trenches."  Despite these challenging conditions, Ford says the 2017 F-150 Raptor completed the course 25 percent faster than its predecessor.

While testing continues on the model, Ford already unveiled the production variant at the North American International Auto Show earlier this year.  It will go on sale in the fall of 2016 and feature a rugged front bumper, ventilated side skirts and 17-inch alloy wheels with BFGoodrich All-Terrain KO2 tires.  The truck will also have a 3.5-liter EcoBoost V6 engine that develops more than 411 bhp (306 kW) and 434 lb-ft (587 Nm) of torque.  It will be connected to a ten-speed automatic transmission and an all-new four-wheel-drive system with a torque-on-demand transfer case that manages power distribution between the front and rear wheels.
