Bricks and Octane is the showroom for official LEGO® cars and racing vehicles — and the fan builds inspired by them. This guide is the two-minute tour: what you'll find, how it's organised, and how to put your own build on the grid.
What you'll find here
Every car we cover is either an official LEGO set or a fan-made model built from genuine LEGO parts. We curate the best of both, sort them by the kind of machine they are, and link straight back to the source — the retailer for a set, the builder's own page for a MOC. We don't sell anything, and we never rehost instructions.
Official sets vs. MOCs
- MOC
- Short for “my own creation” — a model designed by a fan rather than released as an official set. The whole point of a MOC is that someone built it themselves, so we always link back to the creator and their instructions.
An official set comes in a box with a number (like the Technic Porsche 911 GT3 RS, 42056) and step-by-step instructions from the LEGO Group. A MOC is a custom design a fan shares as a parts list plus instructions you buy or download elsewhere. Both are welcome here; each card is tagged so you always know which is which.

How the nine bays work
We sort by the kind of machine first, so you can walk the showroom the way you'd walk a real one — straight to the cars you care about.
- Sports & Supercars — Ferrari, Lamborghini, McLaren and the rest of the exotics
- Classic & Vintage — hot rods, air-cooled icons, and pre-war shapes
- Muscle & Hot Rods — American V8s and street machines
- Race Cars — F1, endurance, touring and rally competition cars
- Off-Road & 4x4 — trucks, trophy racers and trail rigs
- Monster Trucks — Grave Digger, El Toro Loco and the Technic crush crew
- Motorcycles — sportbikes, cruisers and race machines
- Go-Karts — the small-but-mighty corner of the taxonomy
- Movie & Franchise — the DeLorean, the Batmobile and other screen legends
Browse every bay, filter by official sets or MOCs, and sort by what the community is voting up this week.
Open the showroom →Share your own build
Built something? Put it on the grid. You can share four kinds of thing: your own build photos, a link to a MOC you published elsewhere, a review of an official set, or a video. Here's how it goes:
- Create a free account — you'll confirm you're 13 or older.
- Pick a build type and add the car, the brand, and which bay it belongs in.
- Confirm it's an official LEGO subject and credit the original builder if it isn't yours.
- Your first few posts get a quick moderator look; after three approvals you're a Trusted member and publish instantly.
New members are pre-moderated so the showroom stays clean and all-ages. Once three of your submissions are approved, your role flips to Trusted and your posts go live the moment you hit submit.
How we credit builders
Attribution is this community's currency. Every third-party build shows its creator and links back to the source; we use official YouTube, Flickr and Instagram embeds rather than copying anyone's files. If you're a builder and something here isn't credited the way you'd like, tell us and we'll fix it fast.
- Deep links to the source — never rehosted instructions or hotlinked images
- Official embeds for video and photos, with visible credit
- Official LEGO sets and genuine parts only — no clone or knockoff brands
- A non-commercial fan community, unaffiliated with the LEGO Group
