Aston Martin AMR26

I don´t think it brings structur problems, otherwise they wouldn´t do it. For the rear wing it has 0 effect. I think they done it to lift the lower suspension arm and keep the kinematic. Another thing is they can alter this mounting point very easily if they like.

Putting the suspension arms high up makes easier geometrically speaking to achieve a roll center equivalent or above the CG, hugely limiting the body roll, and providing a stable aero platform.

Excessively high roll centers lead to excessive amounts of jacking. Jacking itself can increase roll as counterintuitive as that seems because too much of it means the CoM raises and the RC position changes leading to greater roll angles. I'd say most teams avoid extremes in this regard. They want controlled RC migration.

I love to learn something new every day. Now I feel compulsively in need of reading more about this phenomenon.

To achieve that you need a lot more than have one bar high up...
You need the whole suspension to be higher.

Roll centres don't matter much in Formula 1. There was an age old thread where we discussed roll centres exhaustingly and the conclusion was that for Formula 1 aerodynamics and "tyre patch control" holds precedence.

In the Williams car thread there is a clear front view of the car, and the upper rear leg of the front suspension is placed very similar to what we've seen in the AMR26, but such view has not been available for the Aston Martin car.

In the Williams is clear that the front pull rod, in front view, is obstructing the rear upper leg, so probably the same applies to the Aston Martin.

An unusual suspension layout that looks to have the aim of reducing drag (as per reduction of frontal surface), rather than redirecting flow.

Edit: But AMR26 has front push rod.

Those don't look like wing pylon mounted upper wishbones to me, doubtful it's this years car.

[MtthsMlw]

Yeah I'm not 100% confident it's this year's car. It's not fully assembled here either

[FNTC]

If that's the same car as in the bacelona shakedown then it just appeared to have the wishbones connected to the rear wing support, but it actually is like this and then the rear wing support goes over it. Not sure either if this is this is the same car or not.

Pic for comparison:

Very different car, not the generic show car by any means, but definitely not what they had in Barcelona either.

It was just a mockup for the livery, Newey said so in the stream, the real car is in or on its way to Bahrain.

As part of the team's launch programme, a concept car featuring the AMR26 livery was revealed, with the AMR26 set to appear during pre-season testing in Bahrain later this week.

Those were pictures of last year's car. The brake duct winglet must mount to diffuser in 2026, not the cake tin.

The lack of bodywork beneath the sidepods is remarkable. No other team has this. The width at the base of the sidepod is effectively the width of the fuel-cell/safety-cell/monocoque (note the vertical lines that descend directly from the halo mounts). Straight shot from the forward floor to the gap between the rear tyre and the diffuser. That gap can be seen from the front of the car. Straight groundline. I’ve highlighted it here.

A feat of packaging? Usually components are housed beneath the radiator ducting.

I wonder whether the advantage of creating a linear flow channel to the diffuser by moving several internal components as high as possible, thereby raising the center of gravity, outweighs placing most of the car's internal components as low as possible and, implicitly, a lower center of gravity ...

The smaller fuel tank (from 100+ kg to around 70kg) has increased the packaging space behind the driver.

This decrease in fuel mass/volume and, therefore, the increase in space behind the pilot does not explain why the space around him looks so bulky. Could the reason be that the new, larger air intakes create this bulky and tall volume in the pilot's area? And speaking of the enlarged air intake, it is said that this is because the new engines are more efficient and economical, as they need to consume 40kg less fuel per race, so the engines will have to run as lean as possible, i.e. with higher air ratios than the 2025 engines...
