Analysis
A reserve driver can spend a season learning everything about a Formula 1 team except what it feels like to race its car on Sunday. Leonardo Fornaroli’s new McLaren arrangement addresses that uncomfortable gap, while creating a different challenge: making two demanding jobs fit into one driver’s working week.
McLaren announced on October 19 that Fornaroli will race its MCL-HY in the 2027 World Endurance Championship, including Le Mans, while remaining its F1 reserve. The consequential part is the combination. Regular competition could keep his racing judgment active, but the F1 value will depend on how McLaren protects preparation time and handles competing demands.
A racing seat changes the bargain
There is a distinction between being close to an F1 cockpit and having a substantial racing programme. The first brings access to engineers, procedures and technical discussion. The second puts decisions under competitive pressure, with rivals who do not cooperate with the test plan. Neither experience automatically replaces the other.
Fornaroli made that personal in an interview with Autosport, saying he had missed racing during his reserve season. That is relevant evidence about his motivation, not proof of what the new arrangement will achieve. An enthusiastic driver still needs a programme that gives him enough time to prepare, recover and understand what each team expects.
TENS’s reading is that McLaren is buying two different kinds of readiness. Its reserve needs to be prepared for an unexpected F1 call. Its Hypercar driver needs to deliver repeatedly across a scheduled campaign. One job rewards availability; the other creates commitments. The organisation must reconcile those obligations before a busy weekend makes the decision for it.
The useful comparison is already inside McLaren
This is not the first time McLaren has combined a racing programme elsewhere with F1 reserve responsibilities. In its January 15 announcement, the team named Pato O’Ward as a continuing reserve alongside his Arrow McLaren IndyCar campaign. That same announcement placed Fornaroli in reserve, testing and development duties.
The comparison establishes an organisational precedent, not a guarantee that the arrangements are interchangeable. Different race calendars, travel demands and preparation needs can change the practical cost of the same job title. O’Ward’s listed roles show that McLaren accepts the principle of a competing reserve; they do not reveal the priority rules it will apply to Fornaroli in 2027.
Those rules matter even without a direct race-date clash. A test, a simulator assignment and a long journey can compete for the days around an event. The sensible question is therefore broader than whether two Grands Prix and endurance races fall on the same Sunday: how much useful preparation remains on either side?
Keep the evidence from each car separate
There is already a practical F1 reference point. Formula 1’s October 19 report says Fornaroli’s next practice appearances are planned for Mexico City and São Paulo. It also describes almost 350 kilometres of preparation at Paul Ricard in the previous-generation MCL39, including longer runs intended to simulate FP1 work.
That sequence illustrates why mileage needs a description. A prepared test programme, a current-car practice session and an endurance race answer different questions. Adding their kilometres together would produce an impressive total while concealing what the driver actually learned. For assessing an F1 reserve, the useful detail is how quickly he can apply current procedures and supply feedback the race engineers can act on.
Endurance competition could exercise judgment under traffic and repeated changes in race circumstances. That is a plausible benefit, not a measured improvement in Fornaroli’s F1 performance. A strong Hypercar stint would deserve recognition on its own terms; it would not establish that he can immediately reproduce the same advantage in a different cockpit.
Equally, an early endurance mistake should not become a sweeping verdict on his single-seater ability. The relevant comparison would be his progress within the new assignment, alongside evidence from F1 work. Keeping those assessments separate prevents one conspicuous result from overwhelming the rest of his development.
What would make the arrangement convincing?
Three things would strengthen the case over time: sustained competitive running, continued preparation with the F1 team, and clear coverage when obligations overlap. These are TENS’s proposed measures, not claims that McLaren has disclosed its internal targets. Public announcements confirm the roles; they do not provide a complete operating plan.
The risk is that each programme assumes the other is supplying the missing experience. Endurance racing cannot maintain every current F1 procedure, while simulator work cannot supply every pressure of wheel-to-wheel competition. Someone must own the gaps between the two schedules, rather than simply count the opportunities on each.
For Fornaroli, a full racing season has value without being sold as a promise of an F1 promotion. For McLaren, the opportunity is to keep a reserve competitively engaged while retaining his connection to the Grand Prix operation. The strongest version of this deal will be visible in the quality of that connection when he returns to an F1 garage: prepared, current and able to contribute.
