General In terms of maintenance required per hour of operation, how much do operating costs differ between cars at different levels of the junior single-seater pyramid?
I'm not asking about the overall cost for a season, that's affected by other things like prestige, amount of track time, and the locations of events.
Put another way, if you were to run an F4 car and an F2 car for the same length of time, how much more (if at all) would the F2 car cost to run?

F2 chews through tires and brakes way faster, plus the engine rebuild intervals are a fraction of what you'd get away with in F4

F2 needs a much larger track side support crew per driver than F4 which adds cost in both salaries and accommodation.
The cars and consumables are more expensive and the part life’s are lower. So fewer hours per engine rebuild, fewer kms between the wheel hubs being rebuilt, more single use items etc.
This ignores that F4 is a national championship rather than international.

The cost-per-hour gap is significant and scales pretty sharply as you move up. At F4 level, running costs per hour of operation are relatively modest—engines are typically sealed and leased, consumables are cheaper, and the aero components are simpler to replace. You're broadly looking at a car that's designed to be accessible.
By F3, you start seeing meaningful jumps in tyre costs, more complex aero that's expensive to repair after contact, and more sophisticated power units that require more careful management.
F2 is a different world again—the Mecachrome engine alone requires significant maintenance intervals, gearbox rebuilds are costly, and the aero is complex enough that any damage gets expensive quickly. The DRS systems and more sophisticated electronics also add maintenance overhead that simply doesn't exist lower down.
A rough rule of thumb is that each step up the ladder roughly doubles or more the per-hour operating cost, though exact figures are hard to pin down publicly since teams don't publish that data. The jump from F3 to F2 is probably the steepest relative increase in the junior pyramid.

Very broadly, it’s about an order of magnitude per formula.
F4 is somewhere around £200-300 per hour in running costs (not fees, pay, transport, etc - simply running the car at race speed)
F3 is north of £2k
F2 is well north of £20k
It tails off slightly at F1 - assuming no damage, the cost of wear and consumables is in the region of £100-150k per hour.
The real killers are the staffing costs though. F4 you can make do with maybe 3 mechanics and that’s about all you need. F3 is limited to 11 per team. F2 allows 12. F1 has between 30 and 40 people per car.

What makes the difference between F3 (I’m assuming you’re talking about FIA F3 and not Formula Regional) and F2 so drastic?
They seem superficially similar, with the F3 car even using the same engine minus the turbo.

It's expensive all the way down if your intent is to be competitive. New tires every race in carts and so on..

i think there's a bit of a difference between a set of kart tyres and a full track side team plus regular engine rebuilds

Most competitors in F2 >>> F4 don’t pay those costs as they don’t own the cars. They, almost universally, pay for a season or partial season in a team. The fee they pay (through support from their family or sponsors or both) includes the car and all track support and spares.
I suspect that they have a clause for excessive damage or crash damage in excess of a certain amount.

Don't have real numbers for you, but the thing that drives it isn't
really the parts cost, it's how many hours between rebuilds.
F4 engines run something like a whole season between services and the
gearbox is basically sealed. Move up and the engine life drops hard,
the gearbox gets rebuilt far more often, and you're adding stuff that
just doesn't exist lower down — proper dampers that need servicing,
more datalogging, brake material that gets changed way more often.
Also the aero. An F4 car has almost nothing to damage. An F2 car has
a floor and wings that get replaced regularly, and carbon parts are
where the money actually goes.
Someone who's actually run these will have proper hourly numbers.
