This Terrain Management System (TMS) enables the driver to select varying modes “to optimize” driving dynamics in changing driving conditions--snow, mud, sand, etc. TMS is no doubt a result of Ford’s extensive research into what drivers want from their vehicles. Increasingly, this research points to changing attitudes about what a truck should do. Many younger drivers prefer trucks to “think” more; hence the increasing reliance on electronic control systems for steering, four-wheel drive, braking, and the like. I remember when auto-locking hubs entered the truck market in the mid- to late 1980s. Longtime offroad hunters harrumphed about it, but plenty of truck owners signed on because it made offroad driving easier. We’ll see more of this down the road.
