In Indycar, aero setup is even crazier than #F1!🛠

Example: ‘17 HONDA
Top: Low-Drag Spec (speedways)
Bottom: High-Downf. (road courses)

For the latter, rules allow ~100hp more: despite that, the terminal speed gets SEVENTY km/h lower!

Drag doubles: (675/575)(390/320)^3 = 210%!

THE CRAZIEST F1 PHOTO YOU'LL SEE TODAY!🔥

Cornering produces huge🔵Lateral forces (➡️Fy), equal to the🟢Inertial Force (-m*ay)

The resulting lateral load transfer increases the outer tyre🟣Load (⬆️Fz)

The rear left rim pokes out of the tyre, and the front right lifts!🤯

LATERAL LOAD TRANSFER

Corner to the right➡️The load transfers from the right-hand tyres to the left-hand tyres.

LONGITUDINAL LOAD TRANSFER

Exiting the corner➡️The load transfers from the front to the rear tyres.

Most loaded tyre: Rear Left
Least loaded: Front Right

The consequences are clear:

- The huge lateral force on the rear-left wheel shifts the tyre to the right compared to the rim. Static waves appear, too!
- The inertial force makes the chassis roll to the left.
- The unloaded front-right tyre lifts.
- The suspension becomes asymmetric.

There are also other consequences (Camber, Toe variation, ...?) which are clearly visible from the image.

Comment if you find them!👀

NEW MCL39 ANALYSIS 🧐

Key points:

🟡 Much more aggressive anti-dive suspension design➡️Aim is to stabilise aero under braking
🔴 Vertical side inlets
🔵 Larger, oval airbox inlet
⚫️ New nose?


- Reworked engine cover outlet (not shown)
- Epic livery🔥

Looks like a solid step already!

Consider that, as we approach the last year with this ruleset, visual changes will be smaller (as teams by know all have a working concept, and simply refine it).

Even more so for a WCC-winning team, that has a lot to lose and not as much to gain from a total overhaul

McL is playing mind games already: this photo depicts the OLD car, wrapped in the new testing livery.

The sidepods are vertical indeed.

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: ???
