It's interesting, but to be honest it doesn't quite appeal to me, partially because of the difficulty in enforcement.
My latest thinking on what would be an interesting approach is based on an assumption that an overall team-level spending cap is basically unenforceable. But a price cap for a system or sub-system that is bought in *is* enforceable provided that every team (or even several teams) are guaranteed to have access to it at that price.
So my latest thinking is a milkshake of price-cap/customer cars/technical partnerships. It goes like this:
Designate some number of systems or sub-systems that are believed to be performance critical and specify for each a maximum system/subsystem cost. For sake of illustration, let's say:
- Power Unit - $10M /year
- Gearbox - $4M /year
- Front Wing Assembly - $50k / each
- Rear Wing Assembly - $50k / each
Then you stipulate that these 4 systems must be made available to X number of teams at those costs and that customer units must not be more than Y design revisions behind the 'works' design.
The teams remain responsible for the design/construction/sourcing of those items that aren't on the list, but are guaranteed the ability to purchase at a non-exorbitant cost those other key elements if they choose. Of course, the purchasing team must work out whether their pretty new Red Bull FW will work with their car, but in a way that helps to enforce some of the design responsibility of a constructor that many fans want to retain.
So Mercedes can spend whatever they want, but any team (up to X) can buy in elements of the Mercedes technology at a known (somewhat affordable) cost.
So you maintain F1 as a constructor series, with technical latitude, but put an effective cap on what is needed to buy in the major technologies of the front runners.
I think it's brilliant.
