Formula 1 launches new era with biggest technical changes in history
Formula 1 teams have arrived in Australia for the start of the new season facing the sport’s most significant technical overhaul regarding engines, chassis and fuel.
While the single-seaters appearing at Albert Park may superficially resemble their predecessors, the machines have been completely reimagined over the winter.
Every major component including the power unit, aerodynamics, tyres and fuel composition has been subjected to fresh regulations.
A revolution under the bonnet
The 1.6-litre V6 turbo hybrids remain, but the division between internal combustion and electrical output has shifted dramatically to a near 50-50 split.
Electrical output has tripled to approximately 350kw (470bhp), drastically altering how power is delivered compared to the previous 80-20 ratio.
The complex MGU-H component has been removed to reduce costs, a move instrumental in attracting manufacturers like Audi, General Motors and Ford to the grid.
However, this simplification leaves the vehicles “energy starved”, requiring drivers to manage battery levels constantly as full power becomes impossible to sustain.
Aerodynamic shift and driver comfort
The sport has abandoned the “ground effect” philosophy utilised between 2022 and 2025 which relied on curved venturi tunnels to generate downforce.
Teams must now adopt a “step-plane” design featuring a flat underside, with the central chassis sitting lower than the surrounding floor area.
This regulatory pivot effectively eliminates the stiff suspension setups that previously caused significant back issues for the grid’s competitors.
To further aid racing, the new challengers have been constructed to be narrower, smaller in dimensions and approximately 30kg lighter than the 2025 generation.
Sustainable fuel introduction
The championship has also mandated the switch to fully sustainable carbon-neutral fuels derived from waste biomass or synthetic industrial processes.
Smaller tyres complete the package of changes designed to create a more competitive and environmentally conscious series.
