i want flat floor and aero option for every car

[Brainhulk]

I dont get why people are opposed to it as an option. Put them on if you want, leave them off if you don't.

I just think it's annoying that it's inconsistent the way they have it now. I don't understand why some cars can get it while some cars can't.

The amount of Picard and children in this thread is too damn high.

Umm... Not every single known machine in the universe can have a wing or flat foor on it.

There is a REAL LIFE Toyota Prius Race CAR! If us humans could manage that......

Wings, flat floors, etc don't belong on a Classic Muscle Car. They didn't need them back then, why should they need them now. Look at the Donohue Camaros or the Sam Posey Challenger, they are trophy winning cars and they have stock spoilers and no flat floors.

They didn't have them is not the same as didn't need them.

It's not inconsistent since you just can't put a flat bottom on any street car. You guys have this belief that you can just bolt anything to a car and just drive. Many cars have shrouds attached to the bottom near the engine designed to channel air but street cars are designed with human comfort in mind not racing or aero grip. They have high ground clearance and this promotes air under the car to increase highway mileage. Flat bottoming a car requires repositioning of parts so they are flush with the chassis and then applying a flat bottom that will smooth out any air passing under the car, thing is you'll also need to install wide body kits with air flow channels so you can do something with the air that gets forced into the engine bay/front end. You'll need splitters and an air dam also time in the wind tunnel to figure out how much air you want going over, under and around the car at all speeds. Mind you that is assuming you got a flat bottom to apply to the car and it doesn't create drag or air pockets in places where air can't smoothly flow though.

That looks interesting but it would fail as a race car bulges everywhere and what on earth is that at the front lip is that funneling air beneath the already high car? Exposed tires this car probably disrupts air violently and probably requires a lot of power to go fast. I hope that chin is doing something but the front end height may say otherwise and I don't think a flat bottom would do much but make this car problematic unless they have underbody downforce. I would love to see that in a wind tunnel and watch how many pockets of air develop those exposed tires and the massive nose height difference from the ground. Many cars are simply show cars and that's about it, they usually look fast and go fast in straight lines. Nice to look at but wouldn't be much different from a street car with lots of power and better tires.

That's why it's a drift car.

@Exorcet I get where you're coming from but street cars generate lift at speed(gas mileage thing)

Lift is bad for mileage. The ideal in theory would be 0 lift. Lift and downforce are actually the exact same thing.

and the vast majority do not have air channels built into the bodywork just an opening for the radiator and air intake to get air and that's about the extent of air flow channeling on street cars.

This is a valid point when considering the design of an underbody. An open floor provides a really easy means of dumping hot air. A sealed floor doesn't. Still there are ways around this. One simple one is not having a completely sealed floor. You can also make more extensive modifications to the vehicle, which would go back to the idea of having more tuning options that was brought up earlier.

Now think of this putting a front splitter on a street car, so that is forces more air up towards the front end opening and over the hood/bonnet, just making the car a little more uneven and more than likely slowing it down as well since the air that rushes into the engine bay or front end has to find a way to get out which is usually under the car because there aren't many cars with vents coming from the engine bay that channel air along the car smoothly(I'm not even including brake ducts, nor canards).

This is a good example of why CFD has become so prevalent in aerodynamics and why in the old days, aero teams lived in wind tunnels. Flow (in reality) is a 3D thing. You say a splitter may force more air into the engine bay. This is fair to say. It may also force more air around the sides of the car. This tends to be a good thing because the air is accelerated even more and you get a suction effect on the front end of the car, which lowers drag.

In any case, extensive modifications to road cars has been done. You don't need to start with a race car to add aero to something.

http://hanchagroup.wordpress.com/author/paulwlucas/

Race cars channel air into the bay then to the sides and also up and over the windshield generating downforce and increased stability, can't get that with a street car. Now said street car has a spoiler on the rear and if the air coming over the roof meets the spoiler cleanly you can get a good amount of down force but if it's much greater than what's at the front you are going to have stability issues at high speeds and slow to non responsive steering.(That's my only guess to the relatively low downforce numbers for street spoilers also in conjunction with air not actually being clean).

This could go some way to explaining why PD have given us nearly useless rear wings. Take the average non car person off the street and ask them about rear wings (if they know about them) and they might speak as if the wing thrown on the back of the car makes everything alright by itself. If GT simulated stronger wings, many players might end up understeering into fences and flipping cars. Not to mention the front aero bits in GT Auto are useless so you couldn't balance a good wing even if you knew what you were doing.

I think this is a ridiculous reason to limit wing performance though. Firstly, the game could warn players about an imbalance. Secondly it just plain teaches people to think incorrectly.

But going back to what you said, I don't see a reason why a road car can't generate front downforce. A splitter is a non issue installation if you're leaving the rest of the underbody open. If for some reason you couldn't equip a splitter, there is this:

Some people will laugh, but this is a very good design strategy when it comes to raw downforce.

Fact GT needs to step up it's interface and take the kid gloves off. I want to use the wind tunnel and have control over the heights of spoilers and see where the air flow is the most disturbed on street cars and where is the optimal position for a rear spoiler.

It would be very nice. Placing the position of aero bits and dealing with balance is probably doable in a game like GT. Seeing the flow around the car isn't so easy. At best we could expect crude approximation.

That picture is a great example of what we need in GT, that wind tunnel would go great so we could maximize settings on race cars per course and many of the adjustable super cars as well. Might seem tedious on street cars but would definitely be a great tool for those who are up for learning about aerodynamics and how it comes into play. Flat bottoming street cars and adding diffusers and watching the results. Not sure if PD would give us that now, but GT7 needs to take those gloves off and lose the pacifier, I want to actually do something a little deeper with my cars and tune until it's how I want it. There will be limits but for the known cars that do support the modifications I would greatly enjoy having more hands on to it if only to learn and put into practice. Simulation needs to simulate and well we need to be able to get more hands on with it at least, feels like we went backwards a bit and then stagnated. RM should come back but better, we should see a wide body kit that channels air for maximum speed or one that is set for optimum control choosing which you prefer, then applying it to the chassis built to minimize underbody airflow ahead of the front wheels and channel air out the rear and up towards the rear duct work for cooling purposes. We need more, hell I crave more but I love having GT's breadth of cars. I hope PD can finally start adulterating the game cars are real and learning about them from a game that pushes the boundaries would be a nice way to introduce anyone to the passion of cars, the correct way.

Well said.

Wings, flat floors, etc don't belong on a Classic Muscle Car. They didn't need them back then, why should they need them now.

Trust me, aerodynamics have not gone backwards since the 70's.

Look at the Donohue Camaros or the Sam Posey Challenger, they are trophy winning cars and they have stock spoilers and no flat floors.

They would be last place cars in a field with updated aero.

 

[Giygas]

The SLS Stealth actually manages to come with a flat floor option.

It's rubbish and only useful for Laguna Seca type tracks.

 

[ProjectWHaT]

Most cars don't need downforce. I always laugh when I see a family sedan with an option to put on a small spoiler. The weight would probably help more than the actual downforce that's produced

Some of those spoilers aren't meant for downforce, but to reduce drag through improved airflow and improve gas mileage. You can see that most hybrid cars will have a small decklid spoiler for that purpose.

I think you could. I've worked on a few dozen cars and can't say I remember being under one that looked like it couldn't have a flat floor "installed".
The side rails running along the bottom of every car, where you have the 4 jacking points, are usually the lowest, non moving underbody parts of the car.
When you put a flat floor on a car, you don't cover EVERYTHING, you can do as little or as much as is needed to get the needed effect.
We don't know to what extent flat floors are taken in GT6, unless someone has rolled a flat floor equipped car?

 

[Awong124]

I think on my car, the catalytic converter is actually the lowest part of the car. That's the part that always gets scraped.

 

[eSZee]

Muffler would probably be lower but that's why I said MOVING..
If you can put on a flat floor, you can make adjustments to your exhaust.

 

[ProjectWHaT]

This is the bottom of a GT-R. As you can see the whole exhaust is visible. And it doesn't look like you'll be able to move that.

 

[eSZee]

Thanks for backing my point.

 

[Tenacious D]

(piccie snip)

Are you saying that the GT-R has 80 to 90% of a flat floor? Because that's what it looks like to me.

You guys have this belief that you can just bolt anything to a car and just drive. Many cars have shrouds attached to the bottom near the engine designed to channel air but street cars are designed with human comfort in mind not racing or aero grip.

This is true. I'm coming from the angle of wanting Race Mod for a good number of cars, and making tuners of them too. Hand in hand with a Livery Editor but that's a whole nuther thread.

At the same time, I really want the freedom to tinker, make good looking racers and snap pics of them. I'd like to wax a lot more and persuasively on this topic but I'm just about dead. Maybe tamale.

 

[ace004]

I just had a beatrush aluminum underpanel installed on my evo. It's just like the one on @Exorcet post. I also have a flat aluminum piece at the rear jdm bumper. Im currently waiting for a person on the evo forums to complete the full underbody and start production. And my car is a street car, guess I'm just crazy like that.

 

[Th3Juggernaut]

curious as to what they made it look like so i did photos, 07 Miata before/after flat floor install

 

[Brainhulk]

Think of the pixels they'll save by not having to render every underbody detail. The game will run smoother...

Practicality guys, practicality

And then people will rage about blank underbodies. PD can't win.

 

[pudgiecat]

I know that cars that I have out flat floors on have always handled better afterwards.....

 

[Th3Juggernaut]

I just got my opinion on them lol. I had them on both the Scirocco and NSX-R and did the new seasonals and got silvers after a few laps. Took them off to get the PP back and add more power and semi-easily got golds on first attempt. I'll admit I'm only an average racer though probably someone with more skill could make better use of them if they indeed make the in-game handling better.

 

[TenEightyOne]

There should be exterior mods for almost every car. And multiple exterior options that go beyond what you are asking for. I have said this in other threads. PD comes out with this shiny new aerodynamics model and only gives us a couple of aero options? That's embarrassing. We should have tons of aero options like real cars do.

There should, there should. But there aren't... and if PD are embarrassed then I really don't know why. They shouldn't be.

OP, there shouldn't be flat floors for every car in game, but I agree with the overall consensus that it would be good to make more options available on more cars.

I don't understand the standards gripe though, when you're racing another car you can rarely tell it's standard unless you're right on its jacksie, and even in GT6 replays they're not as horrible as they were. When you're driving them you don't see the car anyway and the lack of a cockpit is pretty meaningless when you're hurtling down The Mountain as the sun comes up.

Didn't mean to go that far off-topic... so yes, more car options please but not that ability to bolt every one onto every car.

 

[Th3Juggernaut]

wanted to see if the 'new new' models were any better, nope lol. kinda makes me wonder why they even bothered wasting time on the flat images like on the Viper, should've just made it blank and spent time on other more appealing stuff.

Anniversary Huayra, FT-1, '13 Viper
