All Terrain Progress Control (ATPC) Retrofit for Land Rover & Jaguar
Take command of steep descents, loose gravel, and rutted tracks—engineered for JLR vehicles, verified against your VIN, and activated through JLR-approved diagnostic pathways.
Off-Road Cruising at Your Chosen Pace
All Terrain Progress Control works like cruise control for difficult ground. You select a target speed between 1.8 km/h and 30 km/h, and the vehicle maintains that pace regardless of the gradient, the surface, or the resistance beneath the wheels. On a steep descent the system applies measured braking to hold your chosen speed. On loose gravel or wet grass it modulates torque delivery to preserve traction. Through ruts and cross-axle terrain it distributes drive across every wheel to keep the vehicle moving forward.
You concentrate entirely on steering and reading the ground ahead. The system handles throttle and braking continuously, which means you keep both hands on the wheel and both eyes on the route. JLR engineers developed All Terrain Progress Control to work alongside Terrain Response and Hill Descent Control, drawing on data from the ABS and ESC modules, the transmission, and the engine management system. You gain genuine composure on terrain where manual pedal control demands constant, tiring adjustment.
Key Features
- Selectable crawl speed spans 1.8 km/h to 30 km/h for gradients from steep descents to fast gravel tracks.
- Automatic speed holding maintains your chosen pace on any slope or surface.
- Progressive take-off pulls the vehicle smoothly away from a standstill on loose ground.
- Brake modulation applies measured deceleration on descents without pedal input.
- Traction preservation reduces torque when the system detects wheel slip.
- Terrain Response integration coordinates with your selected terrain programme.
- Hill Descent Control coordination hands over seamlessly when you exceed its speed range.
- Steering wheel control adjusts the target speed through the existing cruise switch pack.
- Instrument cluster display shows the active set speed and system status clearly.
- Driver override at any time lets you take control instantly through the pedals.
- Low range compatibility works in high and low range where your transfer case offers both.

Installation & System Integrity
Our authorised installation partners follow a meticulous, vehicle-specific procedure. They confirm your existing hardware inventory, fit the control module or switch pack where required, route factory-style wiring harnesses, and activate the All Terrain Progress Control menu through proprietary JLR-compatible software. Our technicians then calibrate the system and complete an off-road test across gradient, gravel, and rutted surfaces to confirm correct speed holding and traction behaviour. This approach ensures the system performs with the same reliability and refinement as a factory-fitted option.
Every component meets or exceeds original equipment standards for off-road durability and long-term reliability. The system undergoes rigorous testing for vibration, water ingress, thermal cycling, and electrical load stability, which guarantees consistent performance across thousands of kilometres of demanding terrain.
Transform Every Off-Road Journey
Upgrade your vehicle with a retrofit that embodies the technical excellence expected of the Jaguar and Land Rover brands. This All Terrain Progress Control system delivers genuine composure and control on challenging ground while preserving the integrity and capability of your vehicle.
