This E23/RS16 in 2017 specs render which seems to come from Enstone, got a wider nose...

Wouldn't they want more air going underneath the car towards the bigger diffusor; thus keeping the thumb-noses we currently see on most cars?
Also, where does it say that the render comes from Enstone? :wtf:

You need to be able to balance out the downforce. Currently the balance is more forward in terms of ease to create downforce, while around 2008 this balance was more rearward.

The 2017 rules will shift this balance further back due to the bigger wing and bigger diffuser, which means it has to be balanced out. How this will be done is anyones guess, but the wider nose is a fairly plausible answer.

It seems like the biggest differences to aero are coming from everything behind the front wheels on the floor. One thing I don't get is why would teams make wider side pods? I get that the floor is wider, but we're still using the same engines with the same cooling requirements as this year. The fuel tank is only increasing by 5%, so aside from the side crash structures, why make wider sidepods? A more aggressive undercut isn't necessary with the much bigger barge boards. Perhaps a slim car has less drag as well.

The ironic thing about the changes next year - less overtaking.

According to FI's Andy Green, the cars will be slower in the straights because of drag and quicker in the corners because of grip. That means shorter braking distances which means overtaking is even harder.

Great, even worse racing than today. Way to go F1!

The shift is going to the floor, an area much harder to disturb by following another car. LMP1 cars don't have a problem following each other.

You really think it's as simple as that? For one, the rear wing is bigger, meaning the DRS can shed a bigger drag percentage. So even if it means that top speeds will be lower (top speeds are this season higher than ever anyways but did that result in more overtaking?) the speed difference between DRS and non-DRS cars should be bigger.
Second, next years cars have a bigger part of the downforce from the floor. That means the downforce is less disturbed by the car in front. The bigger barge boards also means you dont have to use the front wing as much as a flow managing device for the whole car, so it can be more focused on producing more downright downforce. So the cars in general should be less sensitive to dirty air. Dont forget the big increase en mechanical grip too.
Third, next years cars will be much harder to drive, which should cause more mistakes, and that alone could improve racing. And also because the cars will be so much harder to drive, fatigue will begin to play a role in the end of the races.

So I believe in better racing next year, and I am very excited about the new cars :-)

That's one of the reasons the new rules are dumb.
Gordon Murray even wanted thinner tires for those reasons...

And I thought f1 wanted to reduce fuel consumption and increase efficiency, to reduce drag and the reliance on the wings, keep the costs under control and let the team performances converge... but what do we get? heavier and draggier cars, new unnecessary costs, bigger wings and not enough tire testing...
The cars will be heavier than a golf 1!
They only wanted these tires/rules for superficial reasons: make the cars less ugly and faster...
We should have let Pirelli do proper testing before the start of the season with well-known tires (keep the same dimensions) so Pirelli and the teams can tame theme rapidly ant efficiently. Every one agrees the is still much potential in todays tires...
So we can concentrate on the aero; enhancing the racing... many engineers/insiders agree the the new rules have been rushed and the research not sufficient...

Not enough. the new cars still rely too much on that stupid fugly superlarge flat front wing.

Or, the cars will be able to stay much closer to eachother in the corners and have a better ability to attack on the straights 8)

I think it all depends on how teams use their front wings.

If flow structures (and downforce) from the front to the back of the car are still heavily depending on clean air hitting the front wing then we'll still see cars struggling to follow in the corners.

I can't remember where I read it but someone said that the aero concept (ie, how they generate their downforce) for next year's cars is broadly similar to what we have now. Based on that we're likely to see much of the same, the cars will just be going quicker.

The part I am interested in is whether or not the new Pirellis will allow for sustained higher cornering speeds during the race. If they do, it'll put more of a strain on the drivers and we'll probably see more mistakes being made.

Thank goodness for the wider tyres !!! now they will look like a proper race car again !!!

That is the point of the bigger barge boards, it shifts more of the flow directing from the FW .

Nope. Big front wings running in dirty air from big rear wings coupled to a big diffuser means big problems following.

F1 has been here before and the racing was dull.

How much shorter?

Considering the braking force of F1 cars some km/h slower top speed and some km/h faster corner speed entry will not change braking distance significantly. I don´t think this will affect overtaking sincerely, what they can or cannot do on a 100m braking will remain on a 90-95m braking

A lot of subjectivity here :P

Unnecessary costs, or a necessary change to keep fans interest as we all get bored easily when a domination period go beyond 2-3 seasons

And superficial reason, or returning F1 back to its former condition of blistering fast cars, unlike currently when several drivers have complaint about how easy this cars are to drive. Easy to drive and F1 car should never be in same sentence if not ironically
Blackout wrote:We should have let Pirelli do proper testing before the start of the season
I couldn´t agree more on this one. To me this is a great example of how bad cost control can go if not applied with some common sense. Testing can be very expensive, agree, but it´s also necessary. You can´t start a F1 season without extensive testing on the tires all cars will use, to me this looks like a parody #-o
