Raptor’s All-New Terrain Management System Enabled by Transfer Case

All-New 2017 F-150 Raptor

When the all-new F-150 Raptor first hit showrooms, few could foresee the extent of the innovations beyond its high-output engine and new skin. Along with all the power and agility gains comes the most advanced drive mode system in its class* – a cutting-edge Terrain Management System™. It is enabled by an all-new dual-mode transfer case that incorporates both all-wheel drive and four-wheel drive systems and electronic lockers to deliver the ultimate multi-terrain experience.


When combined with the non-sequential 10-speed transmission and high-output EcoBoost® engine, Raptor can deliver its 421 PS** and 678 Nm** of torque more efficiently for the ultimate driving experience – whether you’re on the road or way, way off.


“Raptor’s transfer case provides the best of both worlds, with the natural benefits from all-wheel drive, such as increased traction in rain and snow, as well as extreme off-road capability that comes with a mechanically locked system,” says Tony Greco, Ford F-150 Raptor programme manager.


Ford engineers sought to enhance the daily driving experience of Raptor while preserving its ultimate off-road performance. With the clutch-based feature of the transfer case, drivers can travel on-road using the 4×4 auto setting, which delivers the benefit of four-wheel drive without the repercussions of component damage or driveline binding – something that can occur when drivers try to use mechanically locked systems on high-traction surfaces like pavement.


When Raptor is operating off-road, its electronic shift-on-the-fly system is still available in the form of 4×4 high and 4×4 low – enabling drivers to navigate harsh terrain with confidence and added robustness. In mud/sand mode and Baja mode, the transfer case shifts into 4×4 high, making it optimal for tackling trails and loose or soft ground – as well as engaging in high-speed desert runs. In rock crawl mode, the transfer case employs 4×4 low, enabling intense off-road driving and rock climbing at low speeds, while using an additional gear reduction ratio to provide enhanced capability with improved powertrain response.


The system was performance-tested in approximately 4,000 kilometres of competition testing in the 2016 Best in the Desert series, completing the 1,368-km SCORE Baja 1000 to conclude the season. In the end, Greg Foutz Motorsports team members drove the truck another almost 650 km back to their headquarters in Arizona.
