Removed fixed assist from cars like the RX X1

PD Mighty fine job on the X2 I love it, but are the rear aero flaps working correctly? Looks like they are raising the wrong sides but could be something to do with the thrust vectoring, I dunno enough about the aero to know, any thoughts?

I wonder how long it will take all the geniuses at GTP To figure out the Infinity VGT Has a KERS Boost Button. Better use it guys and cut some lap times with it they wont understand lol


I have a few VGT to get started before I get to the Infinity, Im going to go through each and post up something to start and add more to them after. The Infinity surprised me with the 4.5L V8 I was expecting a VQ or VR variant V6.

No I think it is just wrong. It looks like they are reducing downforce on the inside and increasing on the outside further reducing the overall grip. Strange.

They are also not simulating the propulsion system. I am not familiar with the tech they are trying to simulate but it is obviously using thrust similar to a rocket, and not like a jet engine. The laser propulsion I am aware of does not have the laser mounted on the vehicle and provides heat from a land based station, the advantage is the vehicle not requiring to carry the mass of it's own fuel.

I removed all sources of drag expecting due to the nature of the propulsion the 2X would simply keep accelerating. It doesn't! It is rev limited! PDI claims they had to make adjustments for the propulsion system, they did by making it an arcade type system and not a simulation type system.

I would have been quite impressed if they had actually simulated it but I am quite surprised they went out of their way to imply that they did when no attempt was even made.

So Im not crazy lol. I wonder if they will hotfix it. Or justify it with Thrust Vectoring



Hmm maybe the adjustable transmission will work then, I gotta get home and try it out.

The "Trust Vectoring" Downforce from the Propulsion System seems like the throttle becomes an on off switch for the downforce on throttle its applied, and off throttle shuts it off.

I wonder if that has anything to do with it the "Thrust Vectoring" proving downforce different to the downforce from the active wings Possibly still on as long as Propulsion is being delivered directional thrust down on the car and directional thrust pushing it forward. Its possible the downward thrust is limiting the speed?

I wonder what it looks like in the specDB in CHASSIS where it displays the wing data and active wing details.

Ive seen the vids on the tech in testing where they are sending up the cones via a land based laser. Even the predicted use of the tech in the future seem to use a fixed position laser that is not attached to the vehicle so they have all the power they need on tap. I get the idea of fixing the laser to the car, but they must be seriously predicting much more power in future batteries to keep that thing running for a lap let alone a race. Im unaware how much draw it has, but I imagine its quite a bit.

You can change gears all day long and it makes no difference. It displays gears but there is no affect on acceleration or top speed. Even setting the top speed of the gear box lower does not lower the top speed.

All zeros. The car is simply an arcade game car placed inside gran turismo, it does not use the physics engine like the other cars do. It does have a cd of .188 but reducing that to zero only gives another 10-20 km to the top end to allow for dr

The land based laser is powerful enough to heat oxygen to the point of exploding. This is how that tech works. There is no way a car mounted laser is going to output that much energy let alone have the batteries supplying it on a car with a curb weight of 450kg

All zeros hmm the lil flaps are probably only visual lol

Is there anything spec about the trust that can be manipulated? Like directional change forward thrust pushing the car backwards instead or change the angle of the thrust.

Theoretically As they say and its purely off what they say. The cars thrust is pushing it forward and also down as downforce. Can we change the direction so that the downforce thrust pushes the car forward and what used to be forward thrust pushes up.

I figured its going to take a crap load of juice to power it if its making air plasma burst Im not sure whats more fantasy, the Propulsion system or the battery that's supplying it with power lol. Its almost like the Lazer Propulsion is Possible IF the batteries to power it existed, and the batteries are whats uber far fetched.

I believe Ive figured out the rear flaps are actually not wrong they are genius. Its a bit complicated to explain, but its really simple (weird) I thought they were wrong originally but maybe they are correct.

am calling them "The Revers Downforce Flaps" I'm also not an aerodynamics guy and I'm using a lot of common sense to put this together but I may be completely wrong about it so I'm going to call it a Theory until I can get more insight into my theory.

Also figured out how the thrust acts as downforce and this needs to be explained first

There is a flap in the middle directly below the thruster that raises and lowers Im calling this the "Thrust Flap"

The Thrust Flap stays flat anytime we are not on the brakes and allows full thrust to accelerate the 2X or help it maneuver with The Revers Downforce Flaps. On Brakes and ONLY on Brakes the flap raises up and this blocks the thrust from hitting The Reverse Downforce Flaps from underneath and the Thrust Flap redirects the thrust upwards as to provide downforce while braking. I check and its dropped flat as soon as we get off the brakes, so the thrust vectoring downforce is NOT whats helping it corner. On brakes the Thrust Flap generates downdorce and its only up while braking and this makes it HARD to rotate on the brakes.

In the demo video they try to show us here is the thrust downforce, but notice the red flap at the center, its not clear but the image is to show that red flap controlling the thrust to generate downforce

And it says "Aerodynamic Control Surfaces Laser Propulsion System. Downforce Thrust Vectoring"

It also states in the "Car Info" tab

The variable positions of the thrust cone veins serve to create propulsion and downforce by the simultaneous of this multi-vane adjustability and and a lower Thrust Vectoring Panel and continues to say the downforce created by the multiple techniques actually presses the cars tires contact patch onto the road.

Here is when on Brakes and the ONLY time the flap rises up

This brings us to The Reverse Downforce Flaps Front and Rear (2 sets of flaps at the front only one of them Reverse Downforce Flaps)

On the Rear
The Thrust Flap dropped flat shoots thrust under the laser where its sort of a wing under the rear of the car, the inside flap drops to drag as the thrust is sent under it not over it. The air above it is kind blocked from the flaps and the thrust sent right at them but from under neath very low and far to the rear.

On the Front
We have 2 sets We will call the forward set at the nose the "Front Flaps"

You must login or register to view this content.

The Front Flaps are regular stuff just like a front lip air goes over them and they allow air into the triangular opening that channels air to the front Reverse Downforce Flap behind the drivers arms.

The front Reverse Downforce flaps also do not get much if any airflow from above as they are not really in the air stream.

Picture a jet fighter flying upside down inches above the ground. what happens if he pulls back on the controls

Its not the Flaps UP that are active its the flaps that drop, because we are using the aiflow underneath not over the top. Its like a upside downn jet pulling back on the controls as aposed to them moving the controls to the side because ONLY the side that is dropped is active (Its like pulling back) where both sides would need to be active for it to be like moving the control to the side and it would have to raise up a lot because the air flow is somewhat bloced from hitting the top surface.

Thats whats going on here with the 2x Its hard to explain but the pivot or rotation point ends up pushing the wheels into the ground and my theory is more pressure from this ends up on the front tires vs the rear helping cornering when when give thrust.

My Theory is the inside Reverse Downforce Flaps drop to provide a kinda reverse downforce on the inside to combat lift or roll & aide maneuverability on thrust.

Thrust Cone

You must login or register to view this content.

The thrust cone also gets smaller to give a bigger area in the main cone area where the burst occurs to increase thrust, & the thrust cone gets bigger to make the main cone area smaller to reduce thrust. in addition to speeding up and slowing down the pulses. The size of the Thrust Cone Decreases as Speed increases

Top Speed

I think the RPM reading for the 2X is more about the Pulse Per Min or PPM as the PPM increases speed does too & as speed increases the thrust cone shrinks for the largest burst in rapid fire.

Could the fact its a pulse engine and not a steady thrust engine contribute to why when all drag is eliminated it still has a top speed, this and maybe the small amount of rolling resistance contributing.

The Laser also has a Power On Indicator like computers and stuff

In addition to the KERS system on the brakes the 2X also has solar panels on the rear end that I believe must contribute to the energy recovery.


The wheels use frictionless magnetic bearing wheels

Braking is combination of Brembo magnetic re-gen calipers and the thrust vectoring control surface deploying working as a type of AeroBrake

The integral Body Frame is using unique "layup style" that allows the entire structure to act in unison with the 2X suspension. The main body also incorporates the super rigid propulsion structure which ensures absolute accuracy of the thrust parabola to the laser pulse cone.


I believe the flaps help put grip on the front wheels that are the main wheels steering the vehicle (more so than the rear) for added maneuverability, and very much so when on thrust.

This and the Thrust Vectoring Flap are why the car has some of its cornering characteristics. The common practice of adding grip to the front and removing some from the rear to help rotation or increase oversteer. The 2X achieves with cleaver use of its aerodynamics, thrust vectoring & 4 wheel steering with no driven wheels.

For example when on the brakes the speed reduces incredibly fast as the trust vectoring pushes the car hard into the track working with the magnetic brakes (I believe work similar to roller coaster brakes), the car is extremely stable and also very difficult to rotate. Many have complained the car handles like a bus and understeers, but this is if we use trail braking techniques AS WE DO on regular cars, with the X2 we use trail braking to reduce rotation or excessive oversteer. Its important to scrub off most speed before entering the corner. Trail braking is a braking technique that's used when applicable & to varying levels with different cars, its not a technique that work well with the 2X aside from being used to reduce rotation or excessive oversteer on entry.

Keep in mind as we slow down the thrust is reduced and so the closer to stopped we get the closer to zero downforce from thrust vectoring again similar to traditional downforce on deceleration although no thrust vectoring downforce holding back acceleration.

Then when off throttle, there is NO more thrust vectoring downforce reducing our ability to rotate, the car rotates sharply, and seems to rotate even more when you give throttle while rotating out of the corner sorta oversteering on throttle dynamic like RWD oversteer on throttle but without the driven wheels. I belive the flaps contribute to the increased ability to rotate.

Controlled understeer in and controlled oversteer out. Many race car drivers find this type of set up ideal for the real world racing environment

I will be honest the 2X as theoretically fictional as it is its quite an interesting vehicle and trying to figure it out has been quite fun.

The Whistle found some txt in there that confirms what the name suggest I wonder if this next maintenance will have a gift
