Thanks for all of your replies and suggestions. Here is a little update. I have completely rebuilt the chassis and the front axle, while staying true to the mcpherson suspension. I used smaller shocks in order to achieve smaller strut towers, so I can build a realistic bonnet. The new chassis:

Hey everyone. As for the first update, I will not continue this moc in it's current form. I spent the weekend reevaluating the whole idea. After a few tests, the front axle showed to be quite flimsy and the front strut towers won't clear the bonnet line unless the car will be a small crossover/SUV. This strongly interferes with my wish for this model so I decided to take some time and remove the drivetrain, build a new front axle and chassis. It'll then be a lot easier to find a suitable car to build. Stay tuned, it'll certainly get interesting!

That's actually my biggest concern for now... guess I'll have to build a car with a steep/high bonnet/bulky front around the chassis. Talk Hyundai i30/Veloster, Ford fiesta etc.

This is amazing. A true masterpiece. I especially like how you've used all different kinds of panels to capture sleek the line of the bodywork.

Hi everyone. This will be my first MOC on this website. The supercars that are uploaded here are of course amazing and much engineering and time went into those remarkable models, but for me it got a bit boring, and I wished to see more ordinary engineering solutions replicated with lego technic, so I decided to build a modern fwd-hatchback. The exact model was not yet determined, thats why I'm waiting for your suggestions in the comments below. I want the model to be as accurate as possible so it will will feature: -Mcpherson front suspension/torsion beam rear suspension -drive via 2 coupled l-motors/steering -detailed ex- and interior -81,6mm tires from 42110/roughly 1:8 scale -detailed engine bay This is the chassis that I came up with after a day of work: The front Mcpherson suspension was built with the guidance of Nicjasnos suspension-tutorials: The rear torsion-beam suspension was taken from Sheepos website: I'm now open for any suggestions concerning the exact car manufacteurer (for example Honda,Toyota,VW etc.) and model that I will then try to replicate as accurately as possible. More progress is to come as soon as I have decided on that. Comments questions or critique are wanted and appreciated.

Thanks a lot for your suggestions, however I've decided to use Nicjasno's Mcpherson front-suspension. It is compact, works well and it doesn't have any geometry issues.

Yea thats one of the major issues of this design. Yes, the pivot points are off... guess I will dump this whole setup and think of a different approach to a front axle. Thanks for your answers.

Yes you are right, the cv-joints swing just a bit when the hub rotates. However I decided to ignore this for my purposes because it was just a very small effect. What do you mean by "making the whole axle rotate"? Thanks for your answers so far Yup, figured that out. Do you have any part suggestions to fix this issue?

I sincerely apologize for showing interest in this users model. Next time, I will try to keep my excitement in. I always thought it would be too intrusive to show interest in other peoples creations on the internet.

Hey everyone, this is a driven front axle design that I came up with. I want to use it in an upcoming moc of mine, an rc front-wheel-drive hatchback in lego technic form. I want to make the model as close to real fwd hatchbacks as possible. As you can see, it features a Mcpherson suspension design and a transverse 3-cylinder-engine. The issue that I ran into was the steering. I tried to implement several different steering setups into this axle, (I used different steering links and racks) but I ended up with a lot of unwanted bumpsteer and a significant toe out. Here you can see the geometry issue of this setup. The toe out only increases when the springs are compressed. I'm grateful for every idea that you leave below because unfortunately I'm not able to continue this MOC if the front axle doesn't work well.

instantly recognizable! I love how you captured the details of the real car. Would it convenient for you to show further pictures of the suspension and gearbox?

I recommend implementing the ability to add 1 more yellow shock absorber per side. If you really want to build a sturdy and stiff frame and body, then the weight of will drastically affect your ride height. Adding another shock absorber and mounting the shocks vertically will help.
