Ford's 2017 F-150 SVT Raptor will be available in a SuperCrew model that extends the wheelbase 12 inches and includes four full-size doors to provide rear passengers more legroom.

The SuperCrew Raptor, announced at the North American International Auto Show in Detroit, extends the whelbase of the standard Raptor SuperCab to 145 inches from 133 inches.

The truck is powered by a new high-output 3.5L EcoBoost that makes 411 hp and 434 lb.-ft. of torque. A new 10-speed transmission includes a torque-on-demand transfer case. Greater use of aluminum and high-strength steel reduce weight by about 500 pounds.

The SuperCrew Raptor expands its off-road capability by adding an available Torsen front differential for improved front grip, standard FOX Racing Shox, and front and rear shock canisters that increased to 3 inches from 2.5 inches to increase suspension travel from the current Raptor's 11.2 inches at the front and 12 inches at the rear.

The Ford Raptor has found use with the U.S. Customs and Border Protection's Border Patrol agency, which purchased several hundred around 2011 for its agency to navigate the rugged terrain of the U.S.-Mexico border. The San Diego County Sheriff's Office also uses Raptors.
