Renault R30

[manchild]

I wonder if they could exploit this idea a bit more. Make openings in vertical zone of stepped floor, on each side in the area below the engine, and than either guide air to upper deck, or reshape exhaust cover/outlet to work as diffuser.

There's more than enough space for flow/tunnel near the engine sump, and it seams legal to me.

too late lol, to still build something like that in would take complete redesign, and with next year banning of the multi-deckers it isnt worth it

A hacksaw and some glue...

neater pic, not animated, looks reasonable

I'm a very visual person so you guys have to tell me with a picture or explain in more detail. I don't follow words just like that. In other words I am not buying those explanations that easily!

You aren't allowed to see any bodywork when looking from directly below, so those curved profiles help achieve that.

I have to press you on this one. The airfoil profile? I would still see bodywork from below. So it must be some other reasoning.

Flip the car upside down and look directly down on it, I bet you that the you can barely see through those holes and anything you can see through them is thin air - otherwise yes they would be in breach of the regulations.

I think n smikle's question is why aren't those curved profiles considered bodywork. And the only answer I can come up with is that they must lie on the step plane, and their curvature must be within allowed tolerances for that area.

3.12.4 The boundaries of the surfaces lying on the reference and step planes may be curved upwards with maximum radii of 25mm and 50mm respectively. Where the vertical transition meets the surfaces on the step plane a radius, no greater than 25mm, is permitted.

As has been noted, it's a loophole within a loophole.

I want a more detailed picture of the splitter!!
Looks way different than from the last race and the pics from when the car was in the air.
The center part looks raised and it almost looks like a brawn or williams snow plow, but less pronounced.

[Blackout]

Thank you very much. Very interesting new splitter

[meves]

The new splitter appears to lead to a channel that runs right around under the edge side pods, see below.

[Blackout]

I think this splitter has 3 channels. Two little channels on each side and a big one in the centre.

Not to mention those two top vents in the Malaysia pictures, which some say are cooling vents for under the engine cover, but my gut says those upper cones stem from 2 more holes under the car (I am only 50% sure)...

The top holes are either fed by hot air from radiators, or their purpose is to accelerate air in the coke bottle region. You can see the curve at the bottom. It could be that perhaps hot air from water rad. reached the exhaust manifold and exits after coaling it through slit around exhaust pipe, and that air from oil radiators is fed directly in this top deck.
So, definitely not for louvers-wings.

The upper hole is fed from the underfloor region where the step plane curves inwards towards the gearbox. This thing is a triple deck diffuser.

NOTE: no barge boards here.

The splitter is pretty close to ground,and it looks like the left front is already
lifting off in the corners.

[manchild]

It looks like a double deck splitter.

[BreezyRacer]

I cannot prove it but I believe you'll find that there's another inlet along the front of the splitter to produce a charge along the plank shelf, back to the inlet along the side of the plank.

The inlet/exits you can see are designed to deflect airflow outwards towards the sides to build low pressure in the large flat floor area.

This is in keeping with designs from Mercedes and RB to name a few.

[Blackout]

I totaly agree with you. I bet that the R30 so the Williams hae a central channel in their splitter.

After looking at a couple of images I came to the conclusion, that the revamped Renault is quite a sexy beast. And, as all the sexy beasts in the world, it deserves its own wallpaper.

Would anyone be so kind as to post a hi-res photo of R30 during/after the Malaysian GP? I just need a clear, side-ish picture of the car as a whole, instead of its details/diffusers/etc. Thanks in advance
