Back to the Fuel Rig: What Formula 1 Could Look Like if Refueling Returns

Formula 1 has not seen refueling in its pit stops since 2010, when the FIA banned it due to safety concerns, high costs, and a desire to create closer racing between drivers. For many fans, that era carries a sense of nostalgia, marked by lighter cars, daring strategies, and pit stops that could completely reshape the outcome of a race. Others, however, remember the dangers, from dramatic fuel fires to chaotic pit lane accidents that defined some of the sport’s most frightening moments. Now, with Formula 1 pushing toward sustainability and the introduction of fully synthetic fuels, an intriguing question emerges: what would the sport look like if refueling made a return?

First, pit stops would change dramatically. Today's record-breaking pit stops are completed in less than two seconds, with the fastest ever being 1.80 seconds by McLaren in the 2023 season. During today's stops, pit crews are mainly focused on changing tires and making small adjustments to help with performance and grip. Adding fuel would extend pit times from two to three seconds to 10 to 12 seconds, even with the most efficient rigs. This longer stop duration would shift the emphasis of pit stops back to strategic planning rather than just execution speed. Teams would once again need to balance fuel loads and tire wear, trading off car pace for track position.

What occurs on the track would also change. In today's races, drivers' cars do not get refueled, so they start the race with the cars loaded to the brim. This leads to more weight in the early laps and slower lap times overall. By reintroducing refueling midrace, teams could choose lighter starting fuel loads, making cars faster and more agile at the start. This could produce more overtaking opportunities in the early stages, as well as dramatic changes in pace.

However, with the reintroduction of refueling, safety would become a major concern. The sport has largely moved on from the days of fuel fires and pit lane accidents, but bringing back refueling would demand strict rules and regulations. Advanced fireproofing and standardized fueling systems would be necessary to protect crews and drivers. In addition, regulated flow rates could help reduce the risk of dangerous accidents that were very common in the 1990s and 2000s.

Overall, the biggest argument in favor of refueling would be sustainability. Formula 1 has committed to running on 100% sustainable fuels by 2026. Allowing refueling during the races could help to highlight these green technologies, showing their efficiency under intense racing conditions. Rather than being seen as a step backward, refueling could become a major platform to showcase F1’s push toward a carbon-neutral future. 

While nothing has been confirmed, the prospect of reintroducing fuel rigs is a fascinating one. Longer pit stops would not only add tension to races but could also bring the field closer together at the finish. More importantly, it would shift the spotlight back onto strategic decisions, turning pit stops into high-stakes moments filled with drama and unpredictability. At the same time, Formula 1 could use refueling as a platform to showcase its commitment to sustainability by demonstrating the performance and viability of fully synthetic fuels on the world stage.
