Test Tracks at Millbrook Proving Ground
At a glance
Millbrook Proving Ground is home to an iconic car test track in the UK, offering private track hire, event venues, and its own 5G network. First opened in 1970, the test tracks are still used for traditional vehicle testing, as well as simulated testing in a 1mm surface accuracy digital twin.
Millbrook is best known for its test tracks where it performs repeatable tests in a safe and secure environment. Custom-built to simulate the world’s toughest terrains, they provide an invaluable test, development and location resource at a single, secure and well supported site.
Millbrook's test tracks are available for hire by the hour (subject to training and track permit), for running test schedules using Millbrook's own teams of drivers and engineers, and for filming opportunities.
On-Road UK Test Tracks
The on-road tracks and features make up the majority of Millbrook Proving Ground, with more than 50km of varied surfaces and a range of technical features.
These UK test tracks include:
- Hill Route (aka alpine test track / circuit) – 6.5km of hilly roads with gradients from 6.5% to 26%.
- High Speed Circuit (aka high speed bowl) – 5 lanes of neutral steer, allowing test speeds in excess of 150mph (240km/h)
- City Course
- Outer Handling Circuit
- Steering Pad and Dynamics Pad
- Mile Straight
- Noise generating surfaces for NVH evaluation and an ISO 10844:2014 compliant facility for pass-by noise measurements of vehicles (maximum and minimum noise) and tyres
- Belgian Pavé
Millbrook Track Control assistance is available 24 hours a day.
The 5G network at Millbrook Proving Ground is used for real-time data acquisition and transfer
Millbrook Proving Ground has a 1mm surface accuracy digital twin, used for driver training, vehicle development, and Hardware-in-the-Loop (HIL) simulation
Millbrook's Belgian Pavé test track was built using 3,500 tonnes of granite blocks. It enables fast evaluation of NVH, durability and vehicle structures
The Hill Route is also known as the alpine circuit. It features the highest point at Millbrook Proving Ground
Millbrook's City Course is used for city driving emulation in a low-speed environment
There are four venues at Millbrook Proving Ground, all with direct access to the test tracks
Millbrook supplies its customers with buildings, office spaces and workshops to rent
Millbrook Proving Ground is the ideal location for driver training courses
Off-Road UK Test Tracks
Set in 100 acres of hilly countryside, the Millbrook off-road test tracks provide a comprehensive range of terrains for every type of vehicle from soft-roaders to full high-mobility military-specification vehicles.
These test tracks include:
- Off-road and severe off-road circuits
- One in one - 45º concrete slope
- Gravel hills with up to 35º gradient
- Sand hills with up to 34º gradient
- Gravel road simulating North American unpaved surfaces
- 60% gradient slopes
- 25º traverse
- Wading pond and trough
- Axle bumps
- Severe vehicle twists
- Concrete ditches and kerbs
- Log roll
- Offset sinusoidals
We find the facilities and staff very helpful at Millbrook. Other test sites don’t have an off-road course that accommodates our projects as well as Millbrook’s does.
The off-road test tracks offer a unique facility for the evaluation of powertrains, transmissions, dynamics, braking and active systems
The MAD 5K Challenge is a run raising money for Help for Heroes. It takes place at Millbrook Proving Ground – across the Hill Route and the Off-Road test tracks
Every other year, Millbrook hosts DVD - a military exhibition attended by professionals from across the defence acquisition and support sectors, and military and industry stakeholders
