Why Did the Formula 1 Cost Cap Shrink Long-term Research?

Toto Wolff says the Formula 1 cost cap, about 200 and a bit million dollars a year, shrinks long-term lab work because every engineering resource counts against the cap.

A team has to choose between compute for a front wing that might race in three months and research that might help a later car. He still wants a balance, weighing the lap time a future car could gain against what the current car needs. He does not claim that every speculative project had to vanish. Wind-tunnel runs and CFD simulations are limited too, so the research money cannot be spent exactly as the team wants. Before the cap, unlimited budgets built ultra-sophisticated cars and let Mercedes, Ferrari, and Red Bull leapfrog the rest. Formula 1 wanted every team on the same budgets. Wolff opposed the cap because Mercedes had the resources, and he thought the realistic losses were to Ferrari or Red Bull, not to McLaren or Williams. Closer competition is the benefit he grants the rule.
