About Bricks & Octane

The basics on who we are and what you'll find here.

What is Bricks & Octane?

Bricks & Octane is an independent fan site about LEGO cars, supercars and motorsports — a place to discover official LEGO racing sets, standout fan builds, and guides for building your own. We are enthusiasts, not the LEGO Group.

Are you affiliated with the LEGO Group?

No. Bricks & Octane is an independent, unofficial fan site and is not affiliated with, endorsed by, or sponsored by the LEGO Group. LEGO is a trademark of the LEGO Group, which does not sponsor, authorise or endorse this site.

Does it cost anything to use the site?

No. Browsing Bricks & Octane is free. Some outbound links to shops or building-instruction sites may be affiliate links, which are always clearly marked and open in a new tab.

LEGO cars & racing sets

Finding, comparing and understanding official LEGO car and racing sets.

What kinds of LEGO cars does the site cover?

We cover the full range of LEGO car and racing themes — from LEGO Technic supercars and Speed Champions race cars to City vehicles and licensed motorsport models. Each entry links out to the official set reference so you can check parts, price history and availability.

How do I tell a LEGO Technic supercar from a Speed Champions car?

LEGO Technic supercars are larger, function-heavy models built with beams, gears and working steering or suspension, aimed at older builders. Speed Champions cars are smaller minifigure-scale race cars with simpler builds and licensed liveries. We tag every model so you can filter by theme.

Where can I check whether a LEGO set is retired or still available?

We deep-link every set out to its reference page on Brickset and its marketplace listing on BrickLink, where you can see the release year, retirement status and current pricing. We never rehost that data — always check the source for the latest.

Building & fan MOCs

MOC stands for 'My Own Creation' — an original fan-designed build that isn't an official set.

What is a MOC?

A MOC (My Own Creation) is an original model designed by a fan rather than sold as an official LEGO set. Bricks & Octane showcases standout LEGO car MOCs and links out to the creator's own page and building instructions — we never rehost their images or files.

Where do I get building instructions for a fan car?

Instructions belong to the builder, so we always deep-link out to where the creator publishes them — most often Rebrickable. Follow the source link on any MOC to reach the creator's official page, where you can view, buy or download their instructions directly.

Can I submit my own LEGO car build?

We're building out community submissions. In the meantime, keep your original photos and instructions on your own hosting or a site like Rebrickable and we can link out to them — we credit and deep-link to creators rather than rehosting their work.

Racing & motorsports

The motorsport side — liveries, licensed teams and race-inspired builds.

Do LEGO sets cover real motorsport teams and cars?

Yes. Licensed LEGO Technic and Speed Champions sets recreate real-world supercars and race cars, including liveries from well-known motorsport marques. We note the real-world car behind each licensed model so you can follow its story.

What's the best LEGO car set for a display shelf?

For display, larger LEGO Technic flagship supercars make a statement, while Speed Champions cars are great for building a compact grid of liveries. Our guides compare size, part count and price so you can pick what fits your shelf and budget.

Age & privacy

Who the site is for and how we handle your data.

What's the minimum age?

You need to be 13 or older to create an account. Before you sign up we ask which age group you're in — 18 or older, 13 to 17, or under 13 — and an under-13 answer stops the sign-up, with nothing about the attempt kept. Browsing doesn't require an account or an age. If a visitor tells us they are under 13, or that they are 13 to 17, we switch off analytics, ads and personalisation for that visit, and anything a 13-to-17 member submits is reviewed before it appears.

What data do you collect, and can I opt out?

We store only the age group you pick (never a birth date) and your privacy choices, plus usage analytics only if you press Accept on the cookie bar. You can change or withdraw consent at any time from the Cookie preferences link in the footer, and use our privacy request form to access, export or delete your data.

Using the site

Getting around, searching and staying up to date.

How do I search the site?

Use the search box at the top of any page (or on our search page). Search is typo-tolerant, so a near-miss spelling of a set or theme will still surface the right results.
