Aston Martin Red Bull Racing TAG Heuer RB14

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.

Increase in surface area, potentially less turbulence under the car.
How does it increase surface area and reduce turbulence?

Notice the changes. The area near the central section is slightly curved. It adds a small amout of surface area. It also smoothes the air flow along the central section.

if anything, then the shape of the new trailing edge would suggest reduction of the surface area immediately before it, not increase, that slight bow loses out to the straightened sharper bends it previously had in terms of the length of the edge, so it is probably more about the shape of the flow, not the surface area

Fine if you only look at the trailing edge, but a diffuser is more than just a trailing edge.

You're right; there's more surface area in the central section. And it seems the trade off with the trailing edge is minuscule. They added tiny vortex generating fins underneath too.

Those vortex generators have been there all the time. They are not visible above simply due to a different view angle.

Here is a question. How are those slots and gaps even legal. I know that just about every car has them but shouldn't they be illegal under the double diffuser rule?

The double diffuser rule forbids holes in the floor. Gurney tabs are perfectly allowed and have been around for I think a decade or so.

The double diffuser made use of a wording loop hole regarding the joining of the reference plane to the step plane. This loop hole has been removed.

The slotted gurney flaps on the top of the diffuser are in a space allowed by the rules. The top of the diffuser is 175mm above the reference plane and there must be no bodywork above 200mm above the reference plane. These flaps sit in the 25mm "gap".

Ferrari style mirrors, but it seems they just added additional housing around mirror that simulates Ferrari's set up.

I absolutely love this overly complex cooling air inlet. Because thats what the whole thing is meant to do. Now it also adds an improved rearwing inflow. Science - --- yeah! If it works we may see some new rearwing designs in the second half.

I don't think it's a cooling air inlet.

Always with the next level stuff, this team. Put a Merc or Ferrari engine in this chassis; we all know what the answer would be. When they aren't innovating something themselves, they're taking someone else's concept, and showing them what it will look like in two years...

I think he's talking about the radiator inlet in that photo, its shape, how it interacts with the mirror pylons. Then making a separate point about how the mirror will interact with the rear wing.

The slot on the pylon, though. Something going on there.

Looks like they've just made the very last part of it twin element - perhaps the fairing was showing some flow seperation where the pylon joined without it.
