Sports|The Second Life of Formula 1 Cars

Formula 1 teams spend millions of dollars annually designing, manufacturing and developing inch-perfect machinery, chasing thousandths of a second in performance gains.

The cars, which usually debut in February, are typically retired just nine months later, replaced by the next model. After the final race of the year, the model becomes a heritage car.

That means a Formula 1 team usually has two operational cars, and a spare, that will no longer be raced. What happens to them?

“All of the cars have been prepared for either T.P.C. running,” or the Testing of Previous Cars program, “or a pit-top practice car,” Jim Barker, the heritage and legacy specialist at Williams, said about this year’s cars in an interview last month. “That’s so we can practice pit stops at the factory; we have a complete car ballasted up to a suitable race weight, so it replicates race conditions pretty well.”

T.P.C.s are private test programs for cars that are two or more years old — which for 2026 has been changed to allow one-year-old cars — often to help young drivers, reserve drivers or for race drivers to train during the winter.

“T.P.C. is a very good grounding for teaching people about modern F1 cars,” Neil Oatley, a technical consultant for McLaren Racing, said. “We probably have two or three people a year going from the T.P.C. project to a modern F1 team, building a car, assembling a car, and graduate on to the race team; it’s a good grounding for producing young people to getting used to working on an F1 car.”
