Despite increased government expenditures in England to fix the country’s potholes, Ford is eager to prove it still rigorously tests its cars for their ability to withstand big pavement gaps. According to Ford, its cars go through thousands of miles of tests across two proving grounds to make sure they won’t sustain damage when presented with uneven surfaces.

The Lommel Proving Ground in Belgium goes as far as to include an inch-by-inch recreation of a notoriously porous English road. More abusive road surfaces are simulated at Ford’s Dunton Proving Ground in Essex, England. Ford says that between the two test facilities, it tests every wheel and tire combination sold on its entire European vehicle portfolio.

The budget for this sort of testing is huge, as each test car is strapped with around $2.5 million worth of electronic gadgetry designed to register and record the effect of each pothole strike. Ford uses the data to improve its current suspension systems and design new ones, which will go on to be further refined at Lommel and Dunton.
