Ford pares down F-150 component weight
Ford engineers working on the all-new F-150 pick-up truck were tasked with taking weight out of the vehicle while retaining the work capability expected by owners.
Most are familiar with the increase of high-strength steel throughout the frame and the first-in-class military-grade, aluminium-alloy body, which accounted for approximately 450lb of savings.
So where did the other approximately 250lb of savings come from? Some weight saving has been achieved through the use of the new 2.7-litre turbocharged gasoline engine with its compacted graphite iron (CGI) vee cylinder block, compared with the 3.5-litre gasoline engine. The dry weight of this unit is 440lb compared with 449lb for the larger 3.5-litre V6, so making a contribution of 9lb.
Other notable weight savings come from: fenders, 13.7lb; rear axle, 35lb, electronic parking brake, 26.9lb; transfer casing, 3.8lb; steering knuckles, 23lb; front bumper, 2.7lb. A single iron steering knuckle for example weighs 23.12lb whereas its aluminium knuckle counterpart weighs 11.57lb
Every pound shaved from a variety of components helped the new F-150 give back capability to customers to achieve a best-in-class payload of 3,300lb or best-in-class towing of 12,200lb.
The F-150 also offers a best-in-class EPA-estimated gasoline fuel economy rating.
