Track & Facilities

Fowlerville Proving Ground’s test tracks are open year-round and meticulously maintained to ensure consistent, repeatable test results. Strategically located earth berms add to the aesthetic beauty of the facility while ensuring absolute privacy to all vehicles on the tracks or in testing areas. Parking areas, garages and offices can all be rented based on customer needs.

  • Road A - Straightaway
