The 2017 Ford F­-250 Super Duty Crew Cab 4x2 has earned the highest possible overall safety rating of five stars from the National Highway Traffic Safety Administration.

The safety evaluation is part of the agency’s New Car Assessment Program. To qualify for the top overall score, the truck earned five stars in the frontal and side crash tests and four stars in the rollover evaluation, according to NHTSA.

Super Duty's improved performance is enabled by weight savings of up to 350 pounds through the use of high­-strength, military­-grade aluminum alloy in the body and box,” Ford said in a statement about the safety score. “This leads to more local frame stiffness at strategic locations to deliver considerable improvement in occupant protection. The weight savings is then reinvested into an all­-new fully boxed frame that is more than 95 percent high-­strength steel and up to 24 times stiffer than the previous frame.”

Options include a 360­-degree camera system, adaptive cruise control with collision mitigation, lane­-keeping alert and inflatable seatbelts.
