[PORSCHE] 918 HS (solar supercar)

[braker23]

Hey guys, let me introduce you to my latest MOC, I really want to know what you think of it.

Now this is my first Supercar, cause I usually build trial trucks and tanks. The source of my inspiration was the amazing Porsche 918 Spyder, which I wanted to convert to a solar-electric hybrid car.

First of all, I tried to keep the proportions and details of the real model. Then, I struggled to integrate the solar panel and make it work and look good, thus becoming the first Lego Technic solar supercar to date.

I’ve built it in the 1:10 scale, fully RC, driven by 2 L motors, has a motorized 4-speed sequential gearbox, advanced suspension geometry on both axles. Doors and hood open, has an adjustable spoiler, matching trolley, wiper, mirrors, head lamps, tail lights, brake calipers, and also a detailed interior featuring a working steering wheel, central console with GPS, gauges and pedals, the works :)

Full specs:

Weight: 1950g

Size: 50 x 22 x 13 cm

Transmission: 2 L motors (AWD)

Steering: M motor (working steering wheel)

Gearbox: M motor

Solar acceleration: M motor

Control: 2 IR receivers

Power: 2 AAA battery boxes + solar panel

Front axle suspension: double wishbone

Back axle suspension: multi-link suspension

Manual functions: hood, doors, wiper, spoiler

Features: brake calipers, mirrors, head lamps, tail lights

Stickers: custom-made

But enough talk, I will let the photos and video speak for themselves.

Sorry for the poor quality video, this is my first time I actually did any editing :)

If you want to see the rest of the photos (93 in total), please see my Flickr album: https://www.flickr.c...57668871336033/

Thanks for your time, have a great day :)

Woah!!! That is a very cool car!

I was thinking solar panel actually the source of a power. Now I see there are two battery boxes. How does solar panel actually help?

[Leonardo da Bricki]

Awesome! That is a winner for the innovation category for sure! And the colors are great! (lime is my favorite)

[Alex Ilea]

Awesome model :D

[Lox Lego]

The front end photo with the hood open is my favorite. Nice contrast with colours

Thanks for you kind words, I really appreciate it :)

Well, the solar panel cannot provide more than 7V of power, under direct sunlight, so that's really low for a car of this size and weight.

But this was not my intention, anyway. The car has enough power from the 2 L motors, each connected to one BB and receiver.

The solar panel is there merely to provide a boost in speed, if the sun is shining or if you place it under a desk lamp (see video).

The panel powers an M motor that is connected to the transmission by the 3rd differential (see bottom view photo).

Oh, so it is a hybrid, interesting idea!

[Zerobricks]

Nice to see a hybrid. Very interesting idea with teh solar panel and a nice color choice. I we both know how much you like lime, Braker

Also very interesting position of the central diff, all the way back.

[braker23]

Thanks a lot my friend, I really appreciate your feedback. But that's not the central diff, it's the diff that connects the solar-powered M motor to the drive-train.

NIce to see a hybrid in this Porsche competition. Very nice job on your first super car. The colors are bold and make it stand out.

I like the stroller as a nice nod to the bag in the original Porsche set.

Really good model ! The shapes are quite blocky and probably too many straight lines for a Porsche. The idea with the solar panel is great and unique in the contest, so it would deserve a higher ranking. If you only would have made a detailed description how you made it work / connected it to PF (??)....
