Mini Formula Race Car


Last Updated . Click "Updates" above to see the latest.

This is a small scale formula race car built with stud-less Technic pieces.

The core of this concept is the possibility of using Technic curved panels to build a really small formula race car with functioning steering wheel and a mini V10 piston engine connected to the wheels with a full size differential while having smaller wheels than the differential frame gear.


The curved Technic panels enable making complex shapes without many holes in the bodywork of the car, and this is another example of how small you can go with it while maintaining some mechanical functionality inside.

The model is designed to be made with red body elements where possible. Design with coloured pieces was checked for the pieces availability in red colour (whether the pieces are manufactured in red colour). Physical prototype was made mostly with black pieces.


Apart from the mandatory steering knob in the middle, the steering axle is also connected to a racing style steering wheel which turns while steering with a knob. It could be used for steering, but the wheel is in a tight spot so it's hard to use - but it works!

Mini V10 Engine

At the back you will find a fully functional Technic V10 piston engine which is connected to the rear axle with a differential regardless of the fact that wheels are even smaller than the differential frame gear.

This is achieved by shifting differential one stud up over the axle.

Obviously to achieve this, the engine frame had to be constructed from ground up with multiple tricks in order to fit inside such a small build along the differential and attachment points to the chassis and bodywork, to a point that his Mini V10 takes similar amount of space as Mini V6 built on a small Technic frame. This is almost the same construction as seen in my previous model, the Cyber Cruiser, but with slight modifications made to attach a differently shaped body.

Instructions available on Rebrickable

Step-by-step instructions for the main model in red colour variant are available for free on Rebrickable:

Potential features that could be added by LEGO in the final kit if Ideas Team accepts it:

- Stickers on the body work with fictional brand names from the Lego universe
- Minifigure driver head with a helmet in the cockpit
(with torso if steering knob connection were to be angled with gears instead of joints)
