Renault R30

[Blackout]

What is this ? A normal splindle/arch ?

[Neno]

Blackout, thanks you for many details of R30. Amazing progress in Enstone in the last year, when you compare it the front wing I almost fell from his chair. I believe that the new administration contributed to the development and that next year it will make a winning car. There are rumors that Kubica will certainly stay at Renault, just amazed at the progress in the development of the car.

I love that photos too. Thanks a lot!

I wonder what would be the required changes to make their exhaust layout 'redbullish'. I don't see any space left there.

It's not the first time Renault have used a brace from engine back to the chassis bulkhead. I believe Renault are unique in doing this - I wonder whether their engine has less stiffness than other designs? Deliberate or otherwise. As they are repeating the exercise, I would guess a deliberate trade-off between engine stiffness and the weight/space cost of the strut.

[Blackout]

Ok, thanks.

Yes, the R25 had a similar one... but not the R28 and 29

[volarchico]

yes. the upper one

That picture seems to show they have a lot more ability to change the angle of that flap than is allowed by the regulations!

It may be limited by controlled software and I think it is recorded in data stream which is known to FIA. Btw. what regulations says about flap regulation?

3.18 Driver adjustable bodywork :
A single closed section situated each side of car centre line in the volume bounded by :
- lines 450mm and 800mm in front of the front wheel centre line ;
- a vertical plane which intersects these lines at a distance 250mm from the car centre line ;
- and the inboard face of the bodywork described in Article 3.7.5 ;
is allowed to change incidence while the vehicle is in motion within a maximum range of 6 degrees, provided any such change maintains compliance with all of the bodywork dimensional regulations.
Alteration of the incidence of these sections must be made simultaneously and may only be commanded by direct driver input and controlled using the control electronics specified in Article 8.2. Except when the car is in the pit lane, a maximum of two adjustments may be made within any single lap of a circuit.

I guess they can "zero" the wing at different absolute angles before the race, and adjust it from there. Looks like about 20 degrees rights there to me.

This link is to aid torsional rigidity . Apart from Renault , Williams FW31 had it last year and F1 cars since the Seventies .

So it's staggered to one side?
If it's symmetrical about the longitudinal axis it could be aimed at taking bending loads along the chassis.

Exactly.

Agreed - located that way it would look like it's designed to reduce bending loads

"In terms of aero, Montreal will see the cars running with the lowest levels of downforce so far this year. “It’s only Monza where we will run less downforce,” confirms Vitaly’s race engineer Mark Slade. “We will therefore bring different wings that haven’t been used before to ensure good straight-line speed."

So new wings for Canada. Low DF rear wing was obvious but maybe they will come with new low DF front wing? FW from Turkey seems to be too sophisticated

In Renault podcast from Turkey it was mentioned about new rear and front wing for Canada. Probably tomorrow we will see first paddock photos.
