Ford recently released details on its 2012 F-150 SVT Raptor. The Raptor will return with new updates that include a new Torsen front differential, which will increase grip significantly for the front end of the truck and allow it to pull itself over obstacles and up steep grades, even when the traction is split between the front tires.
Ford also explained in its press release on the 2012 Raptor last week that an internal helical gearset is used to help force torque from the wheel that is losing traction to the wheel with traction. The system is set with a torque bias ratio of 2.5:1 to help multiply torque from wheel to wheel and the preload is set to zero to help minimize steering feedback.
“This system is key for letting Raptor customers tackle new ground in their truck,” said Kerry Baldori, Ford SVT Global Performance Vehicle chief functional engineer. “Its extreme capability lends itself well to rock climbing situations.”
