Random Aerodynamic Oddity of the Day Thread

It reminds me the Fiat Coupé somehow.

Next-gen 911 GT3 secrets revealed! Race car aero and more variants

WHY A SWAN NECK?

Ever wondered why aircraft sling the engines under the wing instead of on top? That’s because on a plane, the top side of the wing is the important part, speeding the air, creating low pressure and thus lift. That area needs to be uninterrupted. Think of a racing car wing as an inverted aircraft wing and you begin to wonder why it took so long for items with unencumbered undersides to appear.

Swan neck, check.

Squiggle in rear diffuser - odd.

Shaping Up

The Porsche Exclusive Manufaktur shapes up the 911 with two aerodynamic and styling packages.

The new Aerokit has been engineered at Porsche’s development centre in Weissach where experts spent months optimizing the design and function. Prototypes were carefully honed in Porsche’s wind tunnel to ensure that the Aerokit fully delivers on its striking visual promise of reducing the uplift forces over both front and rear axle.

The rear engine layout seems to make things more challenging to some extent, but how could anyone not love the Porsche 911?

I think some of the magic is that under full brake load there is a near 50/50 weigh balance.

Stop and weight! A 50/50 weight distribution is not optimal

Having this weight in the back naturally uses all of the tires more efficiently during braking, instead of overloading the front tires which is what tends to happen in a front biased car.................

With more weight over the rear axle, its obvious that there is going to be more traction. Thus, the car can put down more power without spinning the tires..................

Fun cars that reward precision execution.

Some people like the challenge, and the engagement.

I was a rear-engine booster all my life until Mercedes had their blowover crashes at Le Mans. Then, I realized that any fast, light, streamlined vehicle should have a stable glide. Even if it won't get airborne, it could hit a patch of wet ice with a strong crosswind. It should only slide, not yaw.
The 911 is a triumph of engineering to adapt a VW bug for sport. I'd say that it looks distinctive handsome, but not beautiful.

...I found out you can set up a Beetle for terminal oversteer, just like a Porsche.

The ambler 500 signage is a nice touch.

Considering how the good old VW Beetle outperforms some modern SUVs while off-roading, I still appreciate the rear-engine layout. On a sidenote, due to the popularity of the Beetle in my country, I have already seen some front-engined cars rebuilt around Beetle frames, also becoming rear-engined in the process. Sometimes I still consider to do a similar hack into some Japanese econobox from the '90s or a compact SUV.

No doubt it's distinctively handsome, but I actually consider the 911 beautiful.

I added a hose starting from the fog lamp in the front bumper and ending inside the bumper in front of the oil cooler

with the magnehelic instrument connected and the high tube placed in front of the fog light and the low tube at the end of the tube the instrument showed 0 even at a speed of 80 km / h

I just changed the connection method and put the tubes upside down on the instrument and started showing a little bit

so either the air goes from to the oil cooler outside the front bumper opposing incoming air or something is wrong
