Alfa Romeo C39

A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter does not belong here.

Quite a weird mainplane.

Can't remember a mainplane with that profile before.

It's like they mounted it upside down...

But it seems like it's working.

Just like when McLaren mounted their suspension upside down and topped testing timerboards a few seasons ago.

What's the point of these oversized pylons? Are they trying to get more rear-end stability by using the pylons as tail-fin like (or shark-fin like) pieces? But wouldn't these larger pieces cut off airflow to the rear wing under yaw, reducing the rear downforce and stability?

It does seem that it is a shark-fin mimic, but I would think a single Sean neck integrated into the DRS mounting might give a better effect...

A closer look at Alfa Romeo's front end

A closer look at Alfa Romeo's front end

Alfa Romeo have maintained a similar front-end philosophy compared to what featured on its 2019 contender. While many other teams went for narrow noses, Alfa stuck with the regular, flat-top nose cone with apertures at the tip of the nose to feed the S-duct.

The picture shows how the new Alfa continues to feature a very wide S-duct outlet, almost the entire width of the nose cone and just a few centimeters in height.

Left and right of it are new winglets since the second test at Barcelona. It was actually Sauber that debuted this sort of winglets last year, but as other teams copied and optimised the design, Sauber's new winglets are now less aimed at extracting air out of the S-duct - like they previously did by pointing outward.

Also note the pins that extend forward out of the four corners of the tub. The nose cone will fit onto these four pins, and can then be attached with screws from the side to fix it.

I'm quite puzzeled by some of Sauber's/Alfa's aero features.
For example, the s-duct exit position. Most teams put the exit where the pressure is lowest and it's generally located more upstream, at the top of the ''7'' in that pic / at the blue area in the CFD image below, and most teams put those 'r' shaped winglets at the s-duct exit, indeed, to also enhance the air extraction from the s-duct by lowering the pressure at that area.

Even though the massive rule change delayed to 2022 there are still some changes to the technical regulations for 2021, with a new ban on floor slots and a triangular cutout from the maximum width at the rear face of the cockpit entry template, to 650mm from the car centreline at the rear axle line. The idea being to cut some downforce.

Nice illustration from F1.com - looks like Sauber provided a car.

There's also a 3kg increase in the minimum weight - on the power unit increasing from 147kg to 150kg. There is a change of definition making it explicit that 4 studs can be used for the gearbox mounting to the ICE, and a stipulation banning the DAS steering.

Is it just me, or does the AR look a bit "older" than its competition? Do not get me wrong, the fit/finish/attention to detail seems on par, rather it just seems I am looking at a Countach instead of a Huracan???

Exactly my thoughts, just didn’t know how to word it as well......
