" You know those old jokes about American muscle being good for the straightline only? Well, Ford is reinforcing some of those stereotypes with a line lock as standard equipment. How Ford pulled off getting an electronic line lock fitted and approved with all the liability concerns these days is anyone's guess but it is things like this that make enthusiasts grin with approval.
The line lock is part of TrackApps suite which also includes launch control and performance monitoring functions like acceleration timers.
Ford states in the manual the feature is for off-road use only. That begs the question, will Ford record use of the feature and deny warranty claims if they see someone using their line lock daily? Not that anyone would... or would they?
Props to Ford for doing things like this and making the Mustang drag strip friendly right out of the box.
