Tech boosts Australian GP: Midfield attack | Car engine and sports

The Australian GP is not really a race for upgrades due to the distance to the teams’ base and its isolated position on the calendar. Three teams did not bring down any new areas. The show and tell sheet was blank at Ferrari, Haas and Aston Martin.

Opposite Alfa Romeo and Alfa Douri. In a tightly packed midfield, every tenth counts. Alfa again changed the nose and front wing. Even the old version is not old. It was only offered at GP Japan 2022. Chopped into the first flap with a shortened nose at that time.

Jan Monchaux’s design team changed this principle. The nose now flows back into the main leaf, its shape somewhat reminiscent of last year’s Ferrari model. The change necessitated a crash test. The shape of the four wing elements has also been completely redesigned.

Alpha Taurey fell. He is a Red Bull copy in parts. The rounded diffuser corners and the smooth transition of the middle section into the diffuser roof are reminiscent of the RB19’s base edges, which have an outlet and an indented indentation in the middle section. The front part of the floor, which now slopes down in a step, also features Red Bull components. Venturi tunnels, on the other hand, have completely independent entrances.

The rest of the teams came with minor changes. Red Bull on the front wing and rear brake vents, Mercedes on the underbelly edges, Alpine on the halo, Williams on the front wing and McLaren on the engine cover and venturi ducts. A slimmer fairing is said to reduce drag.

Here’s a rundown of updates for Australia:

Red bull

Forewing: The second and third folds have changed in shape and length.

Forewing endplate: The endplate is very curved.

Rear Brake Ventilation: New drum to improve cooling.

Mercedes

Underbody Edge: The mini-wing on the underbody edge is lined with vertical deflectors.

McLaren

Engine Cover: Reduced in size for lower drag.

Venturi channels: The shape of the front venturi channels has been improved.

Alpine

Halo: The fairing has been modified to improve flow to the stern.

Alfa Romeo

Front wing: The shape of the main blade and all three flaps have been changed.

Nose: The nose has been lengthened again and now ends at the main blade instead of the first element. For this, the car was again crash tested.

Rear-view mirror: Modified connection to side compartment and cockpit.

Alpha Dauri

Kilpakkam: The central area around the retaining wall is widened at two places. The climbing area in the front venturi channels received a new shape. The central part of the diffuser below the gearbox has a smooth transition to the rest of the body.

Underbody Edge: The rear of the front venturi channel has received completely new locations.

Venturi channels: Four venturi channels and separating baffles are modified in shape and angle.

Diffuser: The diffuser transitions from the ceiling to the vertical planes and is more rounded.

Williams

Front wing: The flap adjustment between the second and third flaps has been retouched. There is also a gurney flap if needed, requiring more contact pressure at the front to balance the car.

Rear wing endplate: A fin is added to the bottom of the endplate for better flow control.
