A small black motorized car, featured non-offset steering, drive, openable bonnet and doors, with german sedan sport car looking.
After wining 100€ of lego thank to the April rebrickable contest. I choose to buy the following lego set : 42047, 42050, 42046, mainly for the part and the set. With the 42047 and 42046 I have consequently more black panels and lime rims. And I wanted to use it in a moc.
The car is motorized by a L motor with 36/12t and 20/diff gearing which offers good speed and torque. The steering is operated by a servo motor and a special linkage about steering. It uses a non offset steering which enables to rotate the wheel in a small room in the arch of the mudguard. Thanks to this, I have made small arch mudguard which is better for design of course. There is no suspension. The battery box is a lipo version in order to reduce the weight and room taken by it.
Regarding the design, I choose to make a sedan car inspired by german looking car like BMW or Volkswagen. With a sport racing looking, thanks to the lime color on the rims and lower side body, large arch with mudguard, and side panel with black color. The interior is also detailed with the bucket seat and red dashboard.
Also, the doors and bonnet can be opened to see steering mechanism of interior.
See it in video :
As usual I have taken some picture during the dismantling, to enable you to rebuild it.

Good car!
Hello, nope this is a problem of design, you will only have a small angle, because the gearing is 1/20*360 =18° but this is not a problem of handling for this speed.
Hello, after a quick build I realized that the virtual-pivot steering system (A.K.A the non-offset system in your article) with a 12-20 vertical gear mesh is not return-to-center. The vertical axle is always around 18° off with the input axle vertical. This can’t be fixed easily without adding another pair of gear (a 12-20 and a 16-16 one both work here). Do you have any easy way of fixing it? (Though it’s quite easy to add another pair, and there’s enough space inside the chassis for the modification.)
Regards.

Hey whats the length of those lime hoses?
This is the bricklink part 32017 and 32124 (black thin liftarm plate with 2 hole and cross).
What is that black piece connected to the gear for the steering?
The rebrickable link will be soon up for the bill fo material !
Many thank to you ! I have added to rebrickable database 🙂
@Eolindel
Here you can find the lxf file and import it to your private mocs in rebrickable to have a partlist

sorry no, but the part are widespread 🙂
Hi Nico,
Is there any chance that you have a part list ? It would make it easier to gather all the needed pieces.
But it looks great and I hope to be able to make it with my son. The steering mechanism looks especially great in such a small space.
