Here's my closer look at the @redbullracing#RB19
Very much a RB18+ with lots of evolution of the 2022 car. No bad thing given its success and the aero testing limits for RBR this year. #F1#F1Tech#F12023
Suspension follows last season, which has seen other teams follow its raked wishbone set up and low steering rack/trackrod position. #F1#f1tech#F12023
The front wing is heavily loaded in the middle, despite being higher off the ground. Plus, a simpler take on the wing/endplate tricks adopted by Merc and others. #F1#f1tech#F12023
Aero around the floor is aggressive, with a large underfloor inlet, scalloped tunnels and this elegant floor edge flap.
Cleverly twisted in shape to create winglets over the scrolled floor edge. Then running nearly the length of the rest of the floor edge. #F1#f1tech#F12023
The wide sidepod helps push the front tyre wake away from the car. The deep undercut helps feed the rear aero, while still allowing a strong floor edge vortex. #F1#f1tech#F12023
The vivid livery belies the fact only the top half of the car appears to be painted.
Less paint saves weight.
The car is believed to be at the minimum weight limit this year. #F1#f1tech#F12023

I've given a short delay to respect the hard working @WilliamsRacing staff.
But their excellent video on the post-brazil rebuild shows some nice details, we rarely get to see.
Some analysis into the #MV33 brake failure & fire at the #AustralianGP.
RBR said the right rear caliper was stuck on, which would have been detectable by pressure sensors.
So, it wasn't a blocked brake duct (my initial guess).

The heat from the brake being constantly on, set the brake duct on fire.
However, the brake disc did not explode when entering the pits. As the disc was still visible & intact in the pits.
The blast was probably the wheel/tyre failing releasing the air & blowing debris everywhere
So, where does the brake system split to isolate the RR caliper and what parts might be responsible?
The brake system is split front and rear.
The front shares the same pedal and tandem master cylinder with the rear, so we can exclude those parts.
It's been exactly 3 years since Romain Grosjean's huge accident in Bahrain.
The monocoque was on at the @F1Exhibition in Madrid this summer.
I took some time to look over the tub and noted the damage, which included elements I wasnt aware of...

Summarising the crash
The car went intact into the barriers at 197kph, at an angle on it's right hand side. This was the biggest deceleration, 67g.
The car jammed in the barrier and flicked around to the left, breaking apart in doing so, the survival cell remaining in the barrier
2)With the initial frontal hit to the barriers, the nose box wasnt evident on the car or track in the post crash pics.
But some of the nose is still attached to the right, but little remains on the left.
Most of the length of the nose appears to be used in absorbing the impact.
Williams are another team bringing a big update to their car.
The FW45 has had a thorough aero review, with one set of bodywork readied for #AA22 at the #CanadianGP. #F1#F1Tech
The floor is the key change. Mostly the underside, but the inlet fences, floor edge and diffuser are more visible changes. The rear brake ducts are reworked accordingly. #F1#F1Tech
Also the sidepods, feature new inlets and a deeper scallop to the waterslide. Directing more flow to the diffuser. #F1#F1Tech
The first big update to the AMR23.
Heavily revised sidepods, floor edge and cooling outlets. #F1#F1Tech#CanadaGP
The waterslide is narrowed and starts with a distinct edge. This may be to contain the rotating airflow, which marries up with the revised undercut, to create more load over the diffuser. #F1#F1Tech#CanadaGP
The undercut feeds into the floor edge further back and with more more load.
The floor edge has been revised, but not in a substantially different way.
The rear tyre temperature sensor is embedded in the floor (red) #F1#F1Tech#CanadaGP
Corner entry deceleration issues for RBR persist. #F1 cars 'brake' in several ways. There's the hydraulic brakes, hybrid braking and engine braking. All affect how the car slows & rotates into a turn. From inputs at the pedals, calculated by the ECU. #F1Tech#AustralianGP
Simply lifting off the throttle gives engine braking. This map can be varied from the steering wheel button (EB or Torque). Altering the throttle/fuelling at that moment.
More EB (up to a point) gives stability/understeer. Less EB gives more rotation.
Confusing things more are the differential settings, that gave a similar balancing effect on corner entry.
