Lotus E21 Renault

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

I think that the hole in the splitter is connected to a pipe that makes a loop and directs air into the vertical bent splitter support to cool the driver's ****

So the splitter support is a tube that allows air to flow between the nose and the floor. Since we can see all the way through the hole where the support meets the floor in the photo where they are carrying the floor, it is likely that the support tube does not connect to the other internal-floor tube we see in that photo. That tube probably goes to the vertical splitter hole visible in the photo with the crane.

I'm having trouble shaking the thought that the support tube may be related to the "fluidic switch" needed to run a passive drag-reduction device. I obviously don't know, and apologize for ignorant speculation based on no data, but I imagine that there would be a benefit to having a linkage between the somewhat "predictable" air at the front of the car, and whatever airbox/ears/etc. ductwork forms the fluidic switch elsewhere.

At any rate, it is an interesting feature, and I hope we eventually learn more about it.

I agree with ebw. There is one wire cable in it, but I still think it is for air. If it is sensor, that should just go through the cockpit.

Anyway, lots of new things on this car for this weekend.

Just so it's a bit more clear, I drew the path of the air and combined the two shots...

That's quite an interesting flow for the air there...

I wonder what the green and the yellow holes are for, though.

Yes there is a wire through it, a metal structure and on it's connection on the floor there is a metal plate. imo it is to prevent splitter flex, that's all.

Also their barge board received an update. Instead of 4 panels the last 2 panels now also are partially split up, as well as it's tips are raised. Imo this bargeboard shows that it was much more about the vortices these tips shed than "preventing bargeboard stall", which doesnt really happen anyways since everything behind the barge board follows the same direction.

The yellow holes are for sucking more air under the floor, they go into a small tunnel which exits just before the main floor begins. They're pretty common on almost all designs.

I don't believe the red hole does what you think it does, there's way too many bends there, and way more ways of cooling the driver. On the other hand, I have no idea what it is doing.

Green 'holes' are not holes. those are just reflections on the second laser pod.
Yellow holes are not new and they direct air under the floor.

If you check the floor photo and the original one it's quite clear that the splitter support is hollow and that it's connected to the hole highlighted in that photo.

That pipe is connected to the vertical splitter's hole which is used for cooling.
