How much is the car worth, and how much the driver? 600 simulated seasons

It is the argument that never ends, in the pub and online: does the driver win, or does the car? Everyone has an opinion and almost nobody has a number. We had a simulation engine sitting idle and an afternoon to spare, so we did the one thing that settles an argument like this: take the best drivers from five different eras, put them in the worst car on their own grid, and see where they finish.

The result confirms one thing everybody suspected and turns up another we did not see coming at all. First, how it was built — without that, the numbers mean nothing.

The experiment

We picked five seasons spread deliberately far apart — 1994, 2004, 2011, 2016 and 2023 — so that no conclusion would hinge on one particular set of regulations. In each we identified four things: the highest-rated driver on the grid, the lowest, the fastest car and the slowest.

Then we swapped them. Every season ran in two arrangements: the natural one, best driver in the best car and worst in the worst; and the crossed one, exactly the reverse. Sixty full-season simulations of each arrangement, against that year's real grid. In total, 600 seasons and 11,400 races.

The gap between the two arrangements is, quite literally, what the car is worth. Everything else — rivals, circuits, weather, reliability, retirements — stays the same.

The numbers

Average championship position in each situation. Lower is better.

The car is worth about eight places

There is the first answer, and it is blunt. Take the best driver on the grid and sit him in the worst car and he falls from an average of P1.24 to P9.07: nearly eight championship places gone without him doing a single thing worse.

Going the other way the swing is even bigger. The slowest driver on the grid goes from P16.91 to P3.67 on a change of machinery alone — thirteen places. A driver nobody would sign lands in the podium fight because someone handed him the good car.

If you have ever thought Alonso was short of a car rather than short of talent, the numbers back you without qualification. In 2011, in the HRT — the worst machine in the whole experiment, an 8 out of 100 — he finishes ninth on average. Which is roughly where anybody would.

But the car does not hand you the title

Here is the twist that changes the whole reading. Yes, the worst driver on the grid averages fourth in the best car of the year. But he wins the championship in 0.4% of seasons. The best driver, in that same car, wins it 76% of the time.

Same machine. Change only who is inside it, and the title goes from a statistical curiosity to the default outcome. The car puts you on the podium; the driver wins the championship.

It makes sense when you think about how a title is actually won. You do not need to be fastest on any given Sunday: you need to score on all twenty-two, not throw away qualifying, not make the expensive mistake in the wet, not put the car in a wall while running third. The chassis does not do any of that for you.

The one we did not expect: the driver matters more in a bad car

This is the finding that sent us back to recheck the maths.

Compare the two drivers inside the same car. In the best machine of the year the gap between the best driver and the worst is 2.4 places (P1.24 against P3.67). In the worst machine, that same gap explodes to 7.8 places (P9.07 against P16.91).

Talent pays more than three times as much when the equipment is poor. And it is logical once you see it: a dominant car does much of the work by itself, compresses the differences and leaves little room to make a difference — you are leading anyway. A bad car is an open problem every Sunday: you have to invent the overtakes, exploit the chaos, pull the impossible lap out in qualifying, defend positions without the pace to do it. That is where the good ones cash in.

It is exactly what fans have said for decades when they talk about someone "dragging" a car. The simulation, knowing nothing of that conversation, arrives at the same place.

An outlier: 1994

Seasons do not all behave alike, and Schumacher in 1994 is the interesting exception. With the best car he takes the title only 27% of the time, against 100% in 2004 or 2023. Not because he drove any worse: that grid was far tighter at the front, and the Benetton never had the margin a 2004 Ferrari or a 2023 Red Bull enjoyed.

Put differently: the more dominant the leading car, the less anything else matters. Eras of crushing dominance are, in fact, the eras in which it matters least who is driving.

What this experiment cannot tell you

The limits deserve honesty. The two drivers we tested use their real attributes, but the rest of the grid is derived from a form index rather than a full profile: the rivals are a reasonable approximation, not a replica. And the engine does not simulate internal politics, team orders, an off weekend for no clear reason, or the pressure of arriving in Abu Dhabi level on points.

Nor does it measure what a great driver does to a team outside the car: the development work, the benchmark he sets for everyone else, the effect of having him in the other garage. None of that lives in a formula, and it is probably a huge part of the real answer.

What it can tell you, with 11,400 races behind it, is how much the machinery weighs when everything else is held constant. It weighs a lot: about eight places. But not enough to make a champion out of someone who isn't one.

Try it yourself

Every one of these swaps can be built by hand. In What If? you pick driver, car and season and the engine runs the full year against the real grid; if you would rather start from something prepared, there are more than forty ready-made scenarios with the verdict already calculated. And if you want to know what is under the bonnet, we explain it in how the simulator works.

Our suggestion, if you want one: put Hamilton in the worst car of 2016 and watch less where he finishes the championship and more how often he still scores. That is where you see the driver.
