Williams aims to cut drag!👀

💡Here is how:

🔴 More streamlined and smaller engine cover (shark fin is larger).
🟡 Front wing: less mid-span load and less cambered scoop.

Also:
🟣 Switched to push-rod rear suspension!
⚪️ Updated floor edge
🟢 Overbite

Will they top the speed traps? 🤔

Remarkably, Mercedes had a pull-rod rear suspension in ‘23 but used a push-rod in ‘24 and will keep it for ‘25.

Williams kept the pull-rod for last year but is finally switching to the one (push-rod) provided by Mercedes.

Haas' new rear wing is unlike anything seen so far: the cut on the endplate is so extreme that it almost traverses the entire wing!

Other changes:
🔵 Cut behind the front wing endplate;
🟡 Underbite ➡️ overbite inlets;
🔴 Seemingly larger undercut.

'24: P7 in WCC
'25: ???

Ferrari's finally switched to Pull-Rod!💡

A risky change, but possibly worth it...

SF-24: Push-Rod (wheel pushes the rod, which acts on the spring/damper).

SF-25: Pull-Rod (wheel PULLS the rod).

Carbon fibre is more resistant to tension than compression➡️Lighter✅
Also, lower Centre of Mass✅

Its impact on aero is complex, though!

Many other interesting details:
- New front and rear wing
- Completely different mirror mounts
- Wing on the upper part of the sidepod
- Reworked engine cover, sidepods, floor...

A risky bet considering Ferrari’s strong season-end performance, but it was likely needed to maximize the car’s potential.

Who looks favorite for the title: McLaren, Ferrari, or RedBull? 👀

💡Ferrari boldy developed an almost WCC-winning car for the last year of regulations:

- Front suspension: switch to Pull-Rod, different wishbone attachments;
- Sidepods: larger undercut, complex design;
- Shrunk engine cover, sharkfin almost removed, new central outlets;
- Completely new rear wing: different V-shape and tips.

And these are only the most evident changes!

Will this big bet pay off? 👀

McLaren has a completely different upper wishbone compared to Ferrari! 😮

1️⃣ More vertical rotation axis:
- Upper wheel upright will move longitudinally (variable wheelbase);
- More anti-dive;
- Different airflow.

2️⃣ Wider wishbone angle➡️Resists better to longitudinal forces, worse to lateral ones.


Both concepts can work, but which one will have a higher performance ceiling? 👀

KEY Day 1 F1 TESTING STATS 🏎📊

- Driver laps: OCO most (88), STR least (42);
- Team laps: RacingBulls most (154), Aston least (88);
- Push lap: NOR/McL fastest (1:30.430, Mediums), HUL/Sauber slowest (+1.739s, Hards);
- Top Speed in best push lap: Sauber highest (319kmh), Aston lowest (309km/h);
- Perc. of time at full throttle in best push lap: RBR highest (63.5%), lowest Ferrari (59.3%).

Already 'just' 1.265s away from the best 2024 lap (LEC Q2)!

Haas didn't use DRS in their fastest lap as they didn't perform any proper push-laps!

LEC set his best time very early in the morning ➡️Less track grip ➡️Could not stay full-throttle as much as others.

The RB21 looks surprisingly similar to the RB20.

RACE SIMULATIONS - DAY 2

🟠NOR was quickest in all 3 stints, and his last one (on C2) was MONSTROUS!

🔴LEC and 🔵ANT were over 0.5s/lap slower over 54 laps. NOR's advantage in the last stint was above 1s/lap!

NOR was 2.128s/lap quicker than in his 2024 race! Different track conditions, sure, but expect the 2025 cars to have a much quicker pace than in 2024.

Looking at the telemetries of several laps, no car was gaining substantially over the others: power modes seem similar across the 3 teams.

Last year's race pace in Bahrain, for comparison.
