This car was developed on three basic principles : design, building and features. I wish I managed. The car was equipped with a AWD drivetrain, with central 5+R gearbox (with removable top). The V10 engine is on the rear, it’s enable me to place the HOG system near the windscreen. The HOG drives the steering with a 20/12t bevel gear, the  steering wheel is connected do the steering with two u-join and 12/24t gear. A bout the suspension, the car is equipped with independent suspensions based on double wishbone suspensions from the 8145 set. As I said before, the car is the AWD with rear engine, therefore there is one differential on each axle and one central differential. The gearbox is connected after the gearbox and after the gearbox, the engine. The central differential avoid wheel slipping because of the difference of  speed during turning.



The next interesting features are the opened part of the car. First the doors can be opened with two damped shock absorbers. They are placed underneath the seats and are operated with a soft push on the connecting rods, as you can see, the doors are opened in the Lamborghini style. Then, the top is convertible, as mentioned in the name roadster. The top is operated by a damped shock absorber placed under the engine. It’s operated with a soft push on a part accessible in the center of  air-vents. The functioning is based on a parallelogram with a lock point. To finish, the spoiler can erupt, with the 4th damped shock absorbers, placed after the engine. This damped SA operated a connecting rod which lift the spoiler. The release is obtained with a push on a axle under the frame.



To conclude with the design : it was made with the new panel and flex system. It allows me to use light amount of red part and have homogeneous bodywork thanks to the curve of those panels. Therefore I decided to make the instructions.

    Can you please give lego part numbers and with the quantities for all the parts that are used. I want to buy all the parts seperatly and put it together but I want to make sure I get the right parts. Thanks.

    If you mean the 8070 supercar, no there are plenty of parts in addition : gearing, frame, flex system, wheel. With the 8070 you will have enought part to build the frame and the body including the axle but not the transmission neither the system of door and spoiler. Regards.


    On rebrickable, the shock absorber (32181c02) doesn’t appear, it’s a bug or a missing?


    I really like your blog.. very nice colors & theme. Did you create this website yourself or did you hire someone to do it for you? Plz reply as I’m looking to create my own blog and would like to know where u got this from. thanks

    I think it is impossible in lego. If you want a RC car fast and resistant, buy a toy or a pro-model toy of RC car.

    Hello! Great construction. I want make a question: when you need single LEGO parts, where do you buy them? ( websites )

    Thanks, Nicolas, for making these instructions! There are a lot of people who have been following this car’s evolution over many months.

    The building instructions are still in development, I will write a post as soon as they are ready. Regards.

    Great car.
    When are the building instructions ready (I think I have al the pieces to make this car 😉 )

    Yes the light are powered, these light are the kit Elife kit (check my videos youtube with keyword light). However, the battery is empty, I must change it.

    This car is very nice! Nico, are you still planning on creating Building Instructions for this Supercar, as indicated at the end of the video?

    Un très joli modèle !
    J’attends avec impatience les instructions de montage.

    Are the Lights powered? I never saw these lights before.
    The car is fantastic can’t wait for instructions 🙂
