Hypercar 2XV10

[Zerobricks]

It's been a long time since I made a supercar and I wanted to make something new and different,

I have been looking into Chiron's gearbox and found a way to use a single wave selector to actuate two independent gearboxes, this is the 4 speed gearbox:

I used a simillar technique to add another 2 speed gearbox, completing a double 8 speed gearbox:

This is the heart of the car, two double gearboxes forming a double 8 speed gearbox.

Now that I had 2 8 speed gearboxes, I decided to give the car 2 fake engines, each driven by the respective drive side - left wheels for left engine and right wheels for the right engine.

The idea is for the completed model to have the following functions:

• double engine drive system with 2 8+R gearboxes with central differentials
• new type of a paddle shift gearbox
• pushrod suspension on all wheels
• motorized front suspension lifting function
• motorized rear spoiler
• spring operated gullwing doors
• openable engine cover
• openable trunk with

This is the current progress:

Right now I'm already at 2500 pieces and the model is far from finished. I expect the final number of pieces to be around 3500-4000 pieces, rivaling Chiron in part numbers, but beating it in functionality.

It's one of the hardest builds I have taken upon, but so far I'm really proud of it. Of course, I'm also building several prototypes from real bricks in parallel to the digital model in order to improve on the design.

More photos from the real build coming soon.

So the UTE Supercar is dead? Thats sad to hear...

 

What the hell man, Is this a case of "I invented this thing thats kinda cool and kinda useless so I'll build something to give it some purpose?"  i cant really see the purpose of having 2 seperate drivetrains on a manual model.

But hey, if you have fun doing it and just enjoy the engineering challenge, go and do it. With your skill it will probably turn out nicely 

 

The front half looks nice, especially the gullwing doors. But the rear half that curves in so damn exteme...It reminds me of the Ford GT, and I dont like the Ford GT...

Very interesting WIP topic which I will be following for sure!  

I'd love to see more about this 'new type of a paddle shift system'. I am not a huge fan of the bodywork which looks a bit 'boxy', but you're priorities are clearly set in the mechanical field.

Btw, fully agreed here:

The UTE may be coming back after I finish this one.

A lot of my models actually start in such a way, I wanted to do something new that wasn't done before yet mechanically. Making a normal 8+R speed gearbox it's easy and boring IMO.

I wanted the car to have extreme curves in the back, to give it a very aerodynamic look. The narrow width would also not be possible with a gearbox design from Chiron which is much wider.

I will post the pictures of the build as it progresses.

Regarding the bodywork, I will try to play with more angles and such, though the door shape is limited because I can't go any deeper towards the center.

I like the idea for the gearbox concept. It has a lot of gears though which may cause some issues. Have you tried building and testing it?

[Jeroen Ottens]

Interesting mechanics, that's for sure. Was it not possible to have the odd gears on one gearbox and the even on the other side? that way you'd get some sort of double clutch gearbox.

The bodywork is pretty boxy as it is now, I'm curious how it will turn out in the end.

Of course, I built a real-life muck-up and it works fine. I plan to start on the final version in a couple of days.

Could you please elaborate on odd and even gears?

On one side 1 -3 -5 -7 and on the other 2-4-6-8

No idea is this even makes sense in your setup...

I'm using two sequential gearboxes for each drive side. The first, bigger one switches between 0,8, 1, 1,25 and 1,67 gear ratio. The second, smaller gearbox switches between 1 to 2,78 on every second pass, giving a total of 8 different gears. The entire setup is axially duplicated and mirrored to form 4 axial gearboxes. After the gearboxes there's another double gearbox for drive and reverse. Drive is driven by the before mentioned gearboxes, but the reverse is driven from FWD only.

[Zerobricks]

So I started to build the final version of the model IRL. It feels like building a Lego set.

First, in lime green is the secondary gearbox, which switches between 1:1 and 1:2,77 gear ratios:

Joining in blue is the main 4 speed gearbox:

Adding on is a third gearbox in yellow - N/D/R selector:

Built mostly out of panels and beams are the floor halves:

Some additional work on on the rear module:

Rear suspension is installed along with the two central differentials:

Front module is prepared for installation of the gearbox:

Gearbox is installed into the front module, the double V10 engines are also added:

Both modules are now ready to be mated. This is quite a difficult process, as there are a lot of axles which have to be properly aligned:

Successful marriage:

And now the rolling chassis is complete:

 

[Zerobricks]

The model is now more or less finished:

Headlights are functional:

Engine bay can be opened to reveal the two V10 engines:

Spolier in the back can be raised:

A view with everything opened up:

And the most important photo with any technic model:

I plan to take better outdoor photos tomorrow along with a video. Stay tuned for more info.

I am gonna be blunt here, I think the front looks ugly. It reminds me of early Nissan 350 Z. The rear looks very hypercar worthy, I like it a lot better. 

I am intrested to see more of the gearbox on the inside, I am always looking to improve my own designs, and your gearbox madness might give me some new ideas for manual transmissions as well 

I just hope these many universal joints ane not part of the drivetrain, otherwhise this will go against my design philosophy

I also dislike the front end.. Looks really rushed and unfinished. I'd redesign the front end completely.

The U joints are for FWD, they are not needed, but I did not want axles going above the floor.

Interesting, some people dislike it, others say it looks good. I can't change much, because there is the battery box, LEDs motor, switching mechanism and lifting mechanism packed under there. But I will try better next time!

Have you tried a muscle car look for the front end? Just make it straight instead of a ball shape.

That's the idea for the next model

[astyanax]

I think the look is very effective for a "hypercar", in the sense that it gives you that "shock" when first seeing it!

How much resistance is in the drivetrain? I recently completed a 4WD chassis with center diff inside a 6speed manual transmission, and even though I simplified everything as far as possible there is of course a little bit more resistance compared to the RWD counterpart.

Depends on the gear. But it runs smoother than the Chiron in my experience.

Found a nice spot to take pictures and video of the finished model:

Also made a couple of gifs of the motorized functions:

More details in the video:

Overall I'm quite pleased with the finished car. Even though it's not perfect it is miles ahead of my last supercar.

It has a few aesthetic issues, such as the front end and blocky look at certain spots. Having said but I'm going to keep as it is and use it as a reference for my next supercar.

I'm thinking of a large scale muscle car UTE, or an updated version of 8466 - 8466 Neo.

If you're looking for a nickname for this car, I'd suggest "Lophius"...
