What's the point of the chicane at the pit entrance? Doesn't the pitlane have speed limits?

Despite that I'm also confused, and that I haven't seen the documents yet, a think the chicane (that will require embankment work) may indicates that there won't be a speed limit on that point.

The design plan was based on FIA's appointments, it probably may have some reasons for those changes.
And again, remember this changes are not being made with (only) F1 in mind.

Another thread that I've left without updates for a while.
I've just seen the proposal presented by CBA to changes on the track, namely:
(1) (more) escape area;
(2) new wall;
(3) completely new pit entry.



However, AFAIK, there's no planing for when this changes should start to be made.

Might that need much work at all? Here's the current satellite picture.

Seems that they won't demolish the permanent grandstand, they'll just remove the barrier next to the track and use the area in front of the grandstand as runoff. As the runoff is marked with grey, it's possibly tarmac. The new runoff might possibly mean there isn't space for the temporary grandstand of Curva do Cafe.

The pit entry seems somewaht similar to '98 pit entry. (1:25) The only difference seems to be that in the proposal the pit lane starts before Curva do Cafe, in '98 the pitlane started just before the chicane, but there was the white line at Curva do Cafe. But the chicane already exists, anyway. But, I wonder if F1 will use that pit entry chicane.

The chicane already exists indeed, but it's entrance besides being prolonged is thought to be widened.
This is the main concern as this could mean dealing with the banking there.

That proposal picture doesn't show properly whether embankment work is needed.

If the pitlane will be made to start before Curva do Cafe, then embankment is obviously needed.

Another option might be to make the track's inside line the new, longer pitlane, narrowing the racing line. But I just wonder what's the purpose of the long pit entry. If the problem is the last corner, then have the entry between the last two corners and have a concrete barrier at the last corner preventing shortcutting.

At least I don't think the long pitlane has anything to do with bikes.

remove "Thread necromancy, I know." - now irrelevant

Today SPTuris, municipal company that manages the Interlagos circuit, presented a reform plan for the Sao Paulo circuit as part of the second phase of the project planned by the city.

The changes include the construction of a new pit area - exclusively for F1 - at the back straight (Reta Oposta), as well as a new section of stands, an arena for events and concerts behind the new pitlane, a new drag strip on the Retão straight (behind Reta Oposta) in the old circuit, new public access, a new Automotive Museum and skate park on the outside of Curva do Lago and several new sport facilities on the site.

About Curva do Café, a new chicane, not for F1 use, will be built at the outside of this turn for bikes and national competitions.

This changes are expected to be ready for the 2013 Brazilian Grand Prix.

if that means moving the starting grid to the back straight (I assume the one after the Senna-S) then no, thanks.

I second that!

Could F1 ever live with a pit/paddock complex that *wasn't* where the grid was - IndyCar does this at a few tracks, I believe (therefore I assume other series do as well), so why not F1.

We cannot lose the Senna "S" being T1, would completely change the character of the lap, and not in a good way.

Can understand why they want to move the pits - give the teams a pit/paddock complex worthy of F1, plus eliminate the rather marginal on safety pit entry we currently have.

How do you figure that?
A lap is still a lap, the only real difference would be the race start.

Personally, I think the opening sequence of corners at Interlagos (up until the Descida do Lago) is the best in F1 right now, with the possible exception of Spa-Francorchamps up to Les Combes.

nice work , would love the classic venues to have modern facilities and new look like silverstone

Right but the track layout isn't changing, just the location of the pits and S/F line.

Because it improves the racing how?

i didn't say it improves racing , i said the track layout stays the same (this is the classic part ) but improve the venue by building new facilities just like silverstone , i dont think my post was that hard to understand

I don't want to state the obvious, but surely with the red layout, anyone who has a brake failure there or anything is going to have the mother of all head-on crashes about half a second later? Unless of course that highway is being moved, which seems unlikely.

Improve the venue for who though?

Interlagos after track changes.


Two proposals for changes at Curva do Café .

...

They just need to build a second floor over the boxes and build some boxes before the first one.
That will give more room to the racing teams for hospitality.

The straight from the previous (fairly slow?) corner is very short though.

for teams , fans on the track , and tv spectators , because when the buildings and surroundings are good looking , they add to the place

I guess you don't know the track. If you get to go to the PPC you will see the teams like sardines in cans behind the garages. And it's not just office space, it's just too damn tight back there.
