2026 F1 Pre-Season Testing, Bahrain, Week 1
Journalists, pundits, reporters, podcasters… They all have lots to say about F1 testing. But, how are you supposed to pick out the key insights without spending hours listening to podcasts or reading articles
That’s where we come in. Gathering sources and coming to somewhat logical conclusions. Take is as you may. Here’s our hot take all the information we could source.
The 2026 pre-season testing in Bahrain has functioned less like a traditional shakedown and more like a high-stakes engineering autopsy. We are officially in the era of "algorithmic racing," where the 50/50 power split between the internal combustion engine and the electric battery has turned every lap into a complex exercise in energy harvesting. As the dust settles in Sakhir, it is clear that the stability we once knew has been replaced by a chaotic scramble to master the energy harvesting limit.
The Breakdown: Evaluating All 11 Teams
Red Bull Racing: The Power Unit Pioneers
Red Bull has transitioned from a chassis constructor to a full power unit manufacturer, and the early returns are terrifying for the rest of the grid. They haven't just adapted; they’ve rewritten the playbook on how to charge a battery at 300km/h.
Energy Masterclass: Max Verstappen is utilizing an unorthodox downshifting strategy, dropping into 1st gear to spike engine RPMs specifically for maximum energy harvesting.
Straight-Line Superiority: GPS data suggests Red Bull is gaining roughly one second per lap on the straights alone, maintaining deployment long after rivals have started "clipping" or running out of boost.
Mechanical Robustness: Unlike other manufacturers, the Red Bull-Ford unit has shown a highly robust cooling and recovery architecture, allowing for aggressive harvesting over 10-lap stints without destabilizing the car's rear end.
Ferrari: The Reliability Juggernaut
Ferrari has taken a methodical approach, focusing on a "Spec-A" platform that prioritizes mileage and stability over experimental glory runs.
Relentless Mileage: The SF-26 has been exceptionally reliable, with Lewis Hamilton completing 150 laps in a single day—nearly three race distances—to verify fuel tank capacity and consumption data.
Innovative Rear Aero: The car features a diffuser extension that works in synergy with winglets near the rear impact structure to create a "blowing effect" that mimics historical downforce-generating wings.
Strategic Caution: While the car looks "planted," there are concerns that their conventional gear-shifting approach may be sacrificing the "savage" energy recovery seen at Red Bull.
Mercedes: The Tactical Hunters
Mercedes topped the final timesheets with Kimi Antonelli, but the team is spending its energy painting Red Bull as the clear benchmark to influence potential regulatory changes.
Outwash Optimization: The W17 features an aggressive front wing profile designed to push air around the tires more effectively than previous iterations.
Operating Window Struggles: Despite setting the benchmark lap time, the car is proving difficult to keep in its narrow performance window compared to the cooler Barcelona shakedown.
Power Unit "Niggles": Reliability remains a concern, with a suspension-related issue and power unit failures limiting their total mileage early on.
McLaren: The Defending Pragmatists
The defending champions are avoiding the experimental "chaos" and focusing on driver comfort and system mastery.
Tightest Packaging: The MCL40 is one of the tightest cars on the grid, particularly in the coke-bottle section, utilizing a "saddle" centerline cooling system to maximize aerodynamic flow to the diffuser.
Modular Philosophy: The car was designed to be highly modular, allowing the team to quickly integrate innovative ideas observed from rivals throughout the season.
Cognitive Load Focus: McLaren is prioritizing ensuring their drivers are instinctive with the new energy deployment buttons, viewing this as a key performance differentiator.
Aston Martin: The "Newey-ism" Nightmare
Despite the arrival of Adrian Newey, the AMR26 looks like a car in deep trouble, suffering from what observers call a "toxic combination" of unrefined mechanical platforms and power unit anomalies.
Massive Performance Gap: Estimates suggest the team is 4 to 4.5 seconds off the pace of the frontrunners, with the car looking stiff and awkward on track.
Cooling Crises: The engine cover is significantly tighter than rivals, leading to cooling issues even when running in limited power modes.
Mechanical Instability: The car is prone to massive front and rear lock-ups, particularly at Turn 10, suggesting the aerodynamic package is not yet harmonized with the new braking systems.
Alpine: The Strategic Dark Horse
Alpine's decision to halt development on their previous car early to focus on 2026 seems to be paying dividends in technical innovation.
Double-Decked Floor: The car features a complex "double-decked" rear floor section ahead of the rear wheels to maximize downforce.
Resource Allocation: By prioritizing 2026, Alpine maximized their wind tunnel and CFD resources, resulting in a car with unique rear wing concepts designed to optimize airflow attachment.
Podium Contention: Early synergy with the Mercedes power unit has led to predictions of podium contention in the opening rounds.
Audi: The Loudest Mystery
Audi has entered with a radical "zero-pod" concept and an engine described as the "meanest" sounding on the grid.
Thermal Scorch Marks: The car has shown signs of thermal issues, including visible scorch marks on the rear bodywork and a burning smell after several runs.
Slotted Floor Innovation: Audi has implemented a "clever interpretation" of the floor's leading edge, creating a "slotted floor" effect to maximize underbody airflow.
Unstable Harvesting: Drivers are visibly wrestling with the rear end during aggressive energy-harvesting phases, indicating a steep learning curve for the new chassis.
Williams: The Mileage Workhorses
Williams achieved the highest mileage of any team (2,245 km), successfully overcoming their missed Barcelona shakedown.
The "Monolith": The car features a unique vertical aerodynamic element on the inner edge of the bargeboard section that no other team has exploited.
Weight Management: James Vowles admitted the car is currently overweight, and the team is focused on a "diet" to shed mass as the season progresses.
Pull-Rod Front End: Williams continues to use a pull-rod front suspension layout, packaging internal components at the bottom of the chassis for center-of-gravity benefits.
Haas: The Midfield Surprise
Haas has emerged as a surprisingly stable platform, capitalizing on the struggles of much larger teams.
Reliability Leaders: The team logged nearly 400 laps, signaling a stable and predictable platform for the new era.
Specialized Cooling: Technical analysis highlighted their "center-line cooling" strategy, visible through an A-shaped roll hoop intake.
Rookie Ready: The car’s stability has allowed Ollie Bearman to set competitive times, suggesting they enter the season with a solid foundation.
Cadillac: The Polished Newcomers
Cadillac has avoided the "back-marker" tag, appearing as a fully realized and professional outfit from day one.
Detailed Aerodynamics: Unlike many new entries, the car features intricate "mouse holes" and double-decked elements in the rear floor to seal the diffuser from tire turbulence.
Steering Precision: The CA01 features a high-mounted steering track rod designed to maintain constant geometry and provide a linear feel for the driver.
Mechanical Integrity: The team reported a faultless first day of running and logged over 100 laps daily, confirming they are a mechanically sound mid-field contender.
Racing Bulls (RB): The Active Aero Lab
The RB squad is focusing on complex aerodynamic management to navigate the power unit transition.
Dual Actuators: RB is utilizing two front wing actuators to manage adjustable aerodynamics, allowing both upper elements of the wing to move.
Unstable Platform: Telemetry suggests the car is sensitive to the "savage" downshifts used for harvesting, causing the rear end to become light during deceleration.
New Leadership: The team is positioning Liam Lawson as a leader alongside rookie Arvid Lindblad as they navigate power unit "teething" problems.
The Predicted Pecking Order for Melbourne
Position/Team | Status | Reason |
1 - Red Bull | Benchmark | Mastery of the harvesting limit and 1-second straight-line advantage. |
2 - Ferrari | Contender | Relentless reliability and a "vice-less" chassis that completed the most laps. |
3 - Mercedes | Contender | Raw pace is there, but power unit "niggles" and energy algorithms are still unrefined. |
4 - McLaren | Midfield Leader | Stability and system mastery are their strengths, though they currently trail by 0.5s per lap. |
5 - Haas | Midfield Elite | Surprising stability and cooling efficiency have them punching above their weight. |
6 - Alpine | Dark Horse | Innovation and synergy with the Mercedes PU suggest they are podium threats. |
7 - Williams | Midfield | High mileage provides a great data set, but they must shed weight to move up. |
8 - Cadillac | Midfield | A very professional entry that is "safe and competent" but lacks peak downforce. |
9 - Audi | Rebuilding | Extreme design and "savage" harvesting but crippled by thermal issues and instability. |
10 - RB | Struggling | Complexity in active aero is currently overshadowed by an unstable rear end. |
11 - Aston Martin | Crisis | 4 seconds off the pace with a car that is visually undriveable and unreliable. |
The Takeaways
The 10-Second Launch Danger: The new start procedure requires a 10-second turbo spooling sequence. Several drivers fumbled practice starts, leading to fears of a "parking lot" scenario in Melbourne if cars fail to launch on a live grid.
The "Double Prep" Qualifying: Drivers cannot get tires to temperature while also charging the battery to 100% in a single out-lap. Expect traffic in Q1 as teams are forced to run double preparation laps.
The Sound of Raw Power: The removal of the MGU-H means the "muffling" effect is gone. These engines are significantly louder, with Audi and Red Bull described as the "meanest" sounding units.
The "Clipping" Reality: If you see a car's rear lights blinking mid-straight, they have run out of electrical boost. Red Bull is currently the only team consistently deploying for the full length of the straight.
The 2026 season is going to be a brutal development war where the budget cap meets exponential learning curves. Red Bull has the "silver bullet" for now, but in this algorithmic era, a single development update could flip the grid overnight.
