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.
