Refuelling in Formula 1 was once a pivotal strategy, enabling teams to run lighter cars for increased speed. However, in 2010, the FIA prohibited refuelling, compelling teams to adjust to racing with heavier cars full of fuel.
The practice of refuelling has fluctuated in Formula 1 since its inception in 1950, with several notable mishaps occurring over the decades…
The Absence of Mid-Race Refuelling in F1
Since 2010, Formula 1 has disallowed refuelling during races. Competing cars must start with enough fuel to complete the race.
Currently, F1 cars can carry up to 110kgs of fuel at race start, but must provide 1 litre of fuel for FIA examination post-race or face disqualification. In a notable instance, Sebastian Vettel was disqualified from the Hungarian Grand Prix for insufficient fuel, failing to offer a sample for FIA inspection.
Reasons Behind the F1 Refuelling Ban
The FIA’s decision to ban refuelling in 2010 stemmed from safety concerns and logistical costs. Previously, refuelling was challenging due to smaller fuel tanks. Post-2010, car designs accommodated larger fuel tanks, necessitating a strategic focus on fuel management. The ban also aimed to reduce costs associated with transporting fuel equipment globally.
Now, teams pre-fuel cars before races to guarantee completion.
Incidents Stemming from F1 Refuelling
Refuelling mishaps in F1 have led to fires and driver injuries. Kimi Raikkonen experienced minor burns at the 2009 Brazilian Grand Prix due to a fuel spill from Heikki Kovalainen’s car. In 1994, Jos Verstappen was engulfed in flames during a pitstop accident, causing significant burns to him and nearby mechanics.
Recalling the incident, Verstappen described the sudden engulfment in flames and the subsequent struggle to escape the car.
The Uncertain Future of F1 Refuelling
The return of refuelling to F1 is doubtful due to safety and cost concerns. Romain Grosjean and Lewis Hamilton have expressed interest in its return for performance reasons, but it remains unlikely.
F1 Car Refuelling Dynamics
F1 cars are fully fuelled pre-race. During qualifying, if refuelling is needed, cars return to the garage. Strategists must balance the desire for a lighter, faster car against the risk of insufficient fuel for qualifying laps.
Innovations in F1 Fuel Tanks
F1 fuel tanks are uniquely designed for flexibility and safety, resembling a bladder rather than a conventional tank. Positioned for optimal aerodynamics, they comply with FIA regulations and are essential for race strategy.
Refuelling’s History in F1
Refuelling in F1 has had a chequered history. It gained prominence in 1982 with the Brabham team’s strategy but was banned in 1984 for safety reasons, only to return in 1994. Notable incidents include Felipe Massa and Heikki Kovalainen’s pit lane accidents.
Refuelling in Other Motorsports
Unlike F1, series like IndyCar, NASCAR, and the World Endurance Championships still incorporate refuelling, with varying regulations and technology adaptations to enhance performance and sustainability.
