F1 2026: Red Bull and Aston Martin Lead the Cooling Revolution
The upcoming 2026 Formula 1 season marks a significant regulatory reset, impacting both chassis and power unit designs. A key change – the abolition of variable geometry trombettes – has unlocked novel possibilities for packaging the power unit, prompting innovative solutions from teams like Red Bull and Aston Martin.
Rethinking Intercooler Placement for Performance
With the new regulations, teams are reimagining the placement of components like the intercooler. Both Red Bull and Aston Martin have moved the air-to-air intercooler, previously located in the sidepod, to a position under the water and oil radiators, directly above the six-cylinder engine. This unconventional approach is creating unique aerodynamic opportunities.
Red Bull’s implementation is particularly noticeable, featuring distinctive “ears” in the airbox of the RB22. These openings facilitate short connection ducts to the compressor, potentially saving weight and offering further aerodynamic development options. This design allows for more efficient airflow management.
Aerodynamic Refinement and the Pursuit of Efficiency
Aston Martin is also adapting to the new regulations, with Pierre Waché opting for sidepods that feature a ramp towards the floor, creating a significant “Coca-Cola” area. Yet, Aston Martin hasn’t yet fully exploited the undercut in the area below the radiator inlets. It’s anticipated that Red Bull will reduce the size of these forms in preparation for the second test session in Bahrain, potentially freeing up space previously occupied by the heat exchanger.
The initial focus for Red Bull appears to be ensuring adequate cooling, a historical weakness. The team likely prioritized verifying the RBPT-Ford DM01 power unit’s ability to handle the heat in Sakhir, following positive indications from the Barcelona shakedown.
The Red Bull Powertrains Advantage: Reliability and Performance
The Red Bull powertrains engine, developed by Ben Hodgkinson, is emerging as a surprise success. Early testing data reveals impressive reliability, and competitiveness. The RBPT-Ford DM01 has covered 2,609 km, second only to Ferrari’s 2,858 km, and ahead of Mercedes with 2,476 km.
Mercedes’ Toto Wolff has highlighted the Red Bull power unit’s ability to harvest more energy throughout a lap, utilizing unique battery charging strategies. Red Bull drivers, including Max Verstappen and Isack Hadjar, are reportedly shifting up a gear earlier than necessary to increase engine RPM and generate electrical energy.
A New Driving Style and Potential Risks
This aggressive energy recovery method, whereas promising, isn’t without risk. It could potentially strain the transmission connecting the MGU-K to the engine, leading to failures. The gearbox itself is also being subjected to increased stress, particularly in lower gears.
The Red Bull RB22 is still in a developmental phase, and its true potential remains to be seen. The team may reveal more of its capabilities during the final test session in Sakhir or at the season opener in Melbourne.
