The 2016 / 2017 Ford Super Duty is inching closer to production as our spies have caught a number of different prototypes undergoing testing in the United States.

The 2016 / 2017 Ford Super Duty is inching closer to production as our spies have caught a number of different prototypes undergoing testing in the United States.

While the trucks are heavily camouflaged, they will follow in the footsteps of the 2015 F-150 and adopt a massive grille which is flanked by large headlights.  We can also see tow mirrors, vertical taillights and widened rear fenders on the dually variants.

Ford has been relatively tight-lipped about the next-generation Super Duty but the model is expected to feature aluminum body panels and a number of aluminum components. This should enable the truck to be significantly lighter than its predecessor.

Engine options are expected to carryover, so choices should include a 6.2-liter V8 with 385 bhp (287 kW) and 405 lb-ft (548 Nm) of torque as well as a 6.7-liter Power Stroke turbodiesel with 440 bhp (328 kW) and 860 lb-ft (1164 Nm) of torque.
