Ford’s recent patent filing indicates the exploration of a line lock for all-wheel-drive vehicles, aiming to adapt the feature commonly used in rear-wheel-drive vehicles for burnouts.
Ford’s patent suggests a method for implementing line lock in all-wheel-drive vehicles by alternating brake control.
The new system may brake wheels individually or by axle, enabling burnouts with flexibility.
While the patent doesn’t guarantee production, it could enhance performance in vehicles like the Mustang Mach-E GT and the upcoming Mach-E Rally.
MotorAuthority.com has revealed a Ford patent application that delves into the possibility of integrating a line lock system into all-wheel-drive vehicles. This feature, which was introduced in the 2015 Mustang model, is predominantly found in rear-wheel-drive vehicles. It functions by locking the front brakes, allowing the rear wheels to spin freely while the car is stationary. Such a mechanism is primarily beneficial in drag racing, where warming up the tires through burnouts before the race commences is crucial.
The challenge lies in the fact that the traditional line lock mechanism, which focuses on locking brakes on one axle, isn’t straightforward to adapt for all-wheel-drive systems. However, Ford’s recently disclosed patent, dated Sep. 26, 2023, proposes an innovative solution. Instead of spinning all wheels simultaneously, the patent describes using a controller to intermittently brake certain wheels, ensuring each tire gets warmed up in the process. This can be achieved by either braking both wheels on a single axle or targeting individual wheels.
Furthermore, for vehicles equipped with mechanical all-wheel-drive systems, the patent suggests the possibility of disconnecting wheels from the drivetrain when they’re not spinning. The patent also alludes to both conventional and electric-powered vehicles. While the patent’s existence doesn’t confirm its implementation, its introduction could potentially benefit performance vehicles in Ford’s lineup, such as the Mustang Mach-E GT and the teased F-150 Lightning performance concept.
