DPX Concept

[HDT Commodore]

4RR-HFC-DPX Concept:

4 Rotor Rotary-Hydrogen Fuel Cell-DualPower eXperimental

What if: You combined all the advanced performance technology from various models under the body of a single car? Not only that but a road car.

It uses:
My own "Dualpower" system, Rotar4 Rotary petrol engine + Hydrogen fuel cell
twin superchargers
Active aerodynamics (much like the hsr-ii)
no NOS
Guards to guide air around the wheels
Wheels designed to suck the available air into the brakes to cool them
Mid-engine, rear wheel drive
intelligent retractable rain-drop shaped headlights
intelligent windscreen wipers with cover

I would get 5 manufacturers to work on this: Nissan, apparently the r33 had highly advanced tech for its day and we all know how the gt-r doesn't make any sense, they could make the main mechanical system. TVR, they specialise on immensely powerful engines, who else makes an 800hp road car? Mitsubishi, two words: active aerodynamics. Also they specialise in awd systems. (maybe this would persuade them to an encore in performance cars) Mazda, this car uses basically a 787b engine and Honda, to make the most powerful hydrogen fuel cell they've ever put in a car.

DPX-II Concept:

The next evolution including:
My own "Dualpower" system, Rotar4 Rotary petrol engine + Hydrogen fuel cell
twin superchargers
Active aerodynamics (much like the hsr-ii)
Mid-engine
intelligent windscreen wipers with cover
twin air fans like on the 2J
Celicaas' AAAWD (Active Advanced All Wheel Drive, with fully customisable VCD (100%/0% to 0%/100% in 1% increments, controlled by touch screen computer in dash)
Active suspension
Pimp My Ride style interior, minus all the monitors (save weight) including sumbrownkid's Heated and Chilled Cup Holders
Clark's six wheel drive system (6D model only)

There are two versions: 4D and 6D. The D is for drive. They are designed to test the difference between 4 and 6 wheels. The fastest design would make it on the DPX-III.

DPX-III Concept:

Featuring:
engine under debate
Turbo + supercharger (high vs low rpm)
Active aerodynamics (much like the hsr-ii)
Mid-engine
intelligent windscreen wipers with cover
twin air fans like on the 2J
Celicaas and Luminis' AAAWD (Active Advanced All Wheel Drive, with fully customisable VCD (100%/0% to 0%/100% in 1% increments, and left/right torque controll, controlled by touch screen computer in dash)
Active suspension
Pimp My Ride style interior, minus all the monitors (save weight) including sumbrownkid's Heated and Chilled Cup Holders
Luminis' idea for petrol-rear/electric-front drive system
front wheel guards to guide air over wheels
front wheels designed to suck in air for brakes to cool
rear wheel covers with air scoops for brakes to cool
355 rear tires (Pirelli P Zero Rosso)

any ideas or constructive criticism is welcome. If more revision is needed, we'll design a DPX-III P1.

 

[Clark]

Sorry, couldn't resist.

 

[MatskiMonk]

All a man needs is an idea...

 

[Anna+Reece]

Needs more active suspension.

 

[sumbrownkid]

Heated and chilled cup holders.

 

[Celicaas]

Make it AAAWD Active Advanced all wheel drive With a button to make it RWD


and Without TCS

 

[Northstar]

I found a picture from the first test run.

Do you really need 4 Nos tanks? Seems a bit extreme considering Nos isn't road legal(at least in the US).

 

[HDT Commodore]

well, i didn't think it was either, but on pimp my ride they put it in a car that was underpowered, so i thought it must be.

picture is there.

Justin: The explosion picture you posted is gone already.

The ideas for DPX-II list has been updated.

 

[Glubags]

can you please make the DPX-III an airplane and a boat and a car (and maybe a truck) all at the same time please with extra NOS bottles in case it underpowered

that wood be so cool becasue you could use it for anything

 

[Clark]

Needs to have 2 sets of rear wheels like a March 2-4-0 for extra traction.

 

[Murcie_LP640]

but on pimp my ride they put it in a car that was underpowered

Does this look like the face of a man who can be trusted with nitrous oxide?

It's not road legal period.

 

[HDT Commodore]

^good point. NOS not for road version. A racer (like the ZondaR or Ferrari FXX ) could have it though.

Clark: serious? did the march do any good with 4 rear wheels? i see how it would help though.

I would get 5 manufacturers to work on this: Nissan, apparently the r33 had highly advanced tech for its day and we all know how the gt-r doesn't make any sense, they could make the main mechanical system. TVR, they specialise on immensely powerful engines, who else makes an 800hp road car? Mitsubishi, two words: active aerodynamics. Also they specialise in awd systems.

[GranTurismo916]

4RRHFCDPX?

Try memorizing that.

 

[hawkeye122]

Why have a wing on the hood? Just use ground effect or a front splitter.

 

[Carlos]

Lol at NOS. Go KERS!

 

[Northstar]

TVR, they specialise on immensely powerful engines, who else makes an 800hp road car?

Nobody, not even TVR considering these days they use crate GM LS engines.

 

[Eric.]

Have you emailed your mockup to these companies yet?

 

[HDT Commodore]

There's no hood spoiler, that's the headlight. I know, looks stupid. Only bit I'm not happy about. The DPX-II does NOT have that.

I can remember the name by thinking of what stands for, but the next one will just use the DualPower eXperimental off the end in the name.

I won't bother contacting anyone important until at least the second third or fourth models. (not until we run out ideas)

By "who makes an 800 BHP road car?", I meant who has ever made one.

I don't want VW or Bugatti to help, they're the competition! This would be the fastest road car if it was made, so VW/Bugatti would fight back, and we would just keep going until someone gets killed. (Joking)

 

[HDT Commodore]

Updated!

 

[Luminis]

Wouldn't a piston engine make more sense with a hydrogen fuelcell? I mean, rotaries aren't known for their efficiency - which would seem important if you're going for a fuel cell. A twin turbo LS V8 would seem so much more reasonable. It's at least available.

Also, why not just use aan electric motor to power the front wheels with the energy provided by the hydrogen cells? Would net you AWD without the necessary differentials and stuff. Plus, individual torgue distribution between the wheels to potentially assisst the steering?

 

[HDT Commodore]

I've got the pictures there now. Your ideas are good ones, but I'm pretty set on rotary engines. It's not supposed to be efficient in full race mode. Perhaps all but one rotor could be shut down for road driving? The fuel cell was just the best idea I had for the boost from electric motors.

As for the DPX-III, the idea of using the petrol engine for the rear and electric in the front is an excellent idea! I remember how much trouble Ferrari had when they tried to make a 4WD. This should make things a lot simpler.

As for the individual torque distribution, do you mean left/right, front/rear or both. Celicaas already had the front/rear idea.

Where do we think we'll go with the 4 rear wheels. Will the weight be too much? It doesn't look like it'd turn too well. Clark, if you're there, do you think it's worth it? If I did use this idea, the rear wheels'd have to be closer to the fronts.

I think the DPX-III should be ready to go to the brands. It looks to me like we should have it sorted. Of course, I'll link to this thread, you guys all deserve a lot of credit for this.

 

[Clark]

I think maybe ditch the 4 rear wheels, and you can't really have wheel covers over the front wheels, unless you limit the car to have no lock whatsoever.

You need something to put down all your power if you're having it RWD. What section tyres are the rears?

 

[Luminis]

If you just want a performance boost, you might want to read up on the Audi R18 e-Tron quattro. It's KERS on roids, basically. A rotary still seems woefully inefficient, though... But, yeah, most important aspect is that a lot more manufacturers than mazda could potentially get involved for the a V8. hell, you could just purchase a bunch of Chevy V8s, given that you manage to get enough cash to start actual development 👍

As for the DPX-III, the idea of using the petrol engine for the rear and electric in the front is an excellent idea! I remember how much trouble Ferrari had when they tried to make a 4WD. This should make things a lot simpler.

Yeah, it's a pretty common thing with hybrid hyper cars, it seems. The 918 Spyder does that, too, I think. And, again, the R18 e-Tron quattro.

As for the individual torque distribution, do you mean left/right, front/rear or both. Celicaas already had the front/rear idea.

I meant left/right. You could individually assign more/less power and torque to either front wheel, potentially helping with the steering.

Where do we think we'll go with the 4 rear wheels. Will the weight be too much? It doesn't look like it'd turn too well. Clark, if you're there, do you think it's worth it? If I did use this idea, the rear wheels'd have to be closer to the fronts.

I'd stick with two rear wheels. Just make sure they're pretty darn wide. 355 or similar. That should provide plenty of mechanical grip.

I think the DPX-III should be ready to go to the brands. It looks to me like we should have it sorted. Of course, I'll link to this thread, you guys all deserve a lot of credit for this.

Keep us updated on how it's gonna work out

 

[HDT Commodore]

Luminis, you say rotary engines are inefficient, you say they use too much petrol? I hear that the 787B was banned for having too much power for too little weight (the engine not the body), if so, this would be ideal.

And yes, I'll ditch the 6wd.

I'm don't know a lot about tires. Luminis sounds like he knows what he's talking about with tires.

BTW, remember, I have no power, money or resources to make this. I just have to hope at least one of these brands will listen. Mazda, Honda, Nissan maybe, TVR i'm not sure, Mitsubishi however would take some persuading. They have supposed to have stopped with motorsport. Maybe they'll take the chance at one final encore?

 

[Clark]

The 787b only was like that because they sort of bent the rules, and made the car look not very fast. Then the ACO gave the car a break in the rules so it could run lighter and more powerful. For the most power you want forced induction. A twin turbo or V8 like in the M5 or Macca 12C would but better for power-to-weight.

 

[Luminis]

Luminis, you say rotary engines are inefficient, you say they use too much petrol? I hear that the 787B was banned for having too much power for too little weight (the engine not the body), if so, this would be ideal.

Rotaries tent to be very compact in terms of size and make good power for their size (and somewhat, weight), but they also tend to get relatively poor fuel economy compared to piston engines.

Then again, according to what I found on Google, it seems that the R26B four rotor from the 787B weighs in at about 180kg/396lbs. While naturally aspirated, of course. A naturally aspirated LS2 crate engine is supposed to weigh in at 170kg/375lbs - which is rughly the same as the LS7, supposedly. So, yeah, you could just as well fit the LS7, when it comes to weight. Sure, it doesn't make 690HP, but it's not a race engine, after all.

As such, I wouldn't really see a reason to go with a four rotor. Aside from the relatively small size, which shouldn't matter all that much when talking about a hyper car.

I'm don't know a lot about tires. Luminis sounds like he knows what he's talking about with tires.

I'm not that knowledgable. I'd just recommend to use some pretty darn wide tyres. The Viper ACR is running 345 tyres on the rear, so going a little wider than that should be providing plenty of grip. 355 is, to my knowledge, at least still somewhat common

BTW, remember, I have no power, money or resources to make this. I just have to hope at least one of these brands will listen. Mazda, Honda, Nissan maybe, TVR i'm not sure, Mitsubishi however would take some persuading. They have supposed to have stopped with motorsport. Maybe they'll take the chance at one final encore?

You'd be best off by designing the whole thing in a way that it can be carried out by a single manufacturer. It's going to be much harder to get them to colaborate on the whole thing.

 

[Tyger]

Perhaps focus on the specs of the Furai rather than 787B if they are available? It's more recent and I believe designed as a road car.

Good luck, I liked your sketches, reminded me of when I was a kid and used to invent/draw cars, though I was all about the aesthetics, didn't know a thing about the science underneath

 

[W3H5]

Something like...

 

[Luminis]

The Furai is a three rotor, though, so I still think that the R26B is the best comparison. The fact that it's quite old would probably be offset by the fact that you'd have to create a road going version.

 

[HDT Commodore]

OK! Thanks for all the support!

No front wheel covers for the DPX-III

355 tires (does Falken make these? they're my new fav tire brand, their cars look awesome)

I'm undecided about the engine. The 4RR (4 Rotor Rotary) was good for the DPX because the HFC (Hydrogen Fuel Cell was originally going to be in the back, along with the large fuel tank, with only the battery in the front. But the DPX-II'll have the tank & cell in the front, so there's room for a massive engine. Still undecided. I've always like rotary engines. My grandfather said they're good because pistons must keep changing direction, whereas rotarys just go around. Piston engines would be more avaliable too. Perhaps we could use 2 like the veyron?

I think I'll contact one company, if they decline, I'll move on to another. I doubt they'll listen.

I'm using 2 superchargers. Can that be done? Would turbos be better? I personally prefer superchargers.
