Formula 1 has been at the forefront of motor car technology for decades – engineering, aerodynamics, and performance. The sport is now looking to face a new challenge — becoming net zero carbon by 2030. A major step towards this is introducing 100% sustainable fuels by 2026, something that could not just transform motorsport but the wider car industry.
The Demand for Sustainable Fuels
There are projected two billion cars on the road in 2030 and only a small percentage of those likely to be battery-electric vehicles (BEVs). Other solutions are necessary.
Electrification is a part of decarbonization, but it is not an all-solution, particularly in regions where electric infrastructure is still developing. This is where sustainable fuels come in—offering a drop-in solution that can be used in existing internal combustion engines without modification. F1 has been a testing ground for new motor technology for decades. Many of the advances in safety and performance, from carbon fibre chassis to hybrid engines, have ultimately found their way into mass-production cars. Sustainable fuels could be next. As Cleo Abram, video tech journalist, greatly summed it up in a YouTube documentary:
“Think of them as epic group science projects […] all working together to push technology to its limit.”
What Makes a Fuel Sustainable?
Unlike conventional fuels from crude oil, the manufacture of sustainable fuels incorporates carbon-neutral processes. This means that they do not introduce additional CO₂ into the environment. Instead, they employ available carbon in the environment, which is sourced from non-food biomass, direct air capture, or green hydrogen. These raw materials undergo complex chemical processes that yield synthetic fuels that are as effective as fossil-based petrol and diesel.
Formula One has taken great effort in designing its regulations to allow manufacturers some flexibility in developing alternative fuels. However, the prohibition on co-processing — the simultaneous processing of crude oil and renewable feedstocks — is a significant limitation. While this process is beneficial in terms of raising production volume, F1’s decision ensures that the fuel for its vehicles is totally sustainable.
The Science Behind the Fuel
Designing high-performance racing fuel that is efficient and sustainable is no simple feat. F1 Chief Technical Officer, Pat Symonds, has been leading this ambitious endeavor.
“At the time I was first talking to people about this, no one knew what I was talking about, and to be honest I’m not sure I did really, so I’ve done an awful lot of research into it,” Symonds admitted.
Teaming closely with FIA and fuel supplier ARAMCO, the crew has already put 39 separate surrogate blends through the pipes in a quest to get it just right. This testing is being performed on a single cylinder F1 power unit to ensure that the fuel measures up to the sport’s standards of high-performance.
The reach of these advancements could be well beyond the speedway, however, says Ross Brawn, F1’s Managing Director of Motorsports:
“We’re working on an E fuel where the carbon circle is completely neutral so the carbon utilised to produce that fuel is the same quantity as the carbon emitted from the internal combustion engine. It means that the engines do not add anything to the carbon dioxide in the atmosphere.”
Most significant of all, the new fuel will be backward compatible with today’s road cars, a practical solution for the billions of internal combustion engines already on the planet.
More Than Just Fuel: The 2026 Power Unit Regulations
F1’s sustainability drive goes beyond fuel technology. The 2026 regulations will focus even more on hybrid technology, with a three-fold level of electrical power provided by the MGU-K, the kinetic energy recovery system. In addition, cars will run on lower fuel loads, decreasing from 100kg in 2020 to just 70kg in 2026, reducing overall fuel consumption.
Cost is also an important factor. The removal of the MGU-H, a sophisticated and costly energy recovery system, will lower engine costs and enhance their application to road car technology.
The Bigger Picture
While a transition to sustainable fuels is a significant milestone, it is not the silver bullet that will transform F1 into a carbon-neutral sport. The fuel that actually goes into racing accounts for just 0.7% of the sport’s total carbon emissions. The biggest environmental challenge remains transferring the teams, kit, and people around the world for a record number of events. But F1’s commitment to green fuels sends a clear message to the motor industry. As Symonds put it:
“There’s going to be a lot of people wanting the product… but the many energy suppliers involved in Formula 1 are more than capable of producing what we need.”
Experience has shown that when F1 focuses on technology advancements, they often trickle down to mass-market cars. From turbo-hybrid engines to intelligent aerodynamics, the technology applied in motor sport tends to find its way into the ordinary car. As Brawn put it:
“If the objective is the best sustainable fuel, then manufacturers will pour millions into development to try and achieve that and then we get all the benefits for the wider society.”
F1’s switch to 100% sustainable fuels by 2026 is not just about making the racing better—it’s about shaping the future of mobility. Being a fan of the sport or not, its latest innovation may just find its way into powering your next car.
