Track & Facilities

FTTA’s Fowlerville Proving Ground is open year-round, as tracks are meticulously maintained and cleared of snow and ice during the winter season 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 are all available based on customer needs.
