Off the blocks: LEGO and Formula 1 reunite for documentary on viral Miami Grand Prix stunt

LEGO’s ten life-size, drivable Formula 1 cars, which stunned fans at the Miami Grand Prix, are back in the spotlight in a new documentary revealing how engineers built them from nearly 400,000 bricks each

When ten full-scale LEGO Formula 1 cars rolled onto the circuit at the Miami Grand Prix in May, they became one of the most talked-about spectacles of the 2025 season. Built by 26 LEGO specialists over 22,000 hours, each car was assembled from almost 400,000 bricks, weighed 1,500 kg, and could reach 20 km/h.

The creations, produced in partnership with Formula 1 and all ten teams on the grid, were driven by all 20 F1 drivers during the official Drivers’ Parade, marking the first time LEGO had produced multiple drivable big builds simultaneously.

Now, that viral moment is the subject of a new 48-minute documentary — Bricks on Track: Building the LEGO® F1® Drivers’ Parade — taking fans behind the scenes of how the extraordinary project came together. The special, produced by the award-winning studio JustSo, features never-before-seen footage of the builds and interviews with the designers, engineers and drivers who brought them to life.

Released this week by the LEGO Group and Formula 1, the trailer reveals the scale of the challenge facing the company’s model-production team as they worked to deliver ten fully drivable cars for one of motorsport’s most-watched events.

The programme includes insights from LEGO Group Head of Design William Thorogood and Formula 1 presenter and former driver Naomi Schiff, who guide viewers through the technical and creative process behind the project.

From the intricate sponsor detailing to the authentic Pirelli slick tyres, the builds were almost exact 1:1 recreations of the sport’s real machines. Each car contained about a tonne of LEGO bricks and 500 kg of mechanical components, designed to be both functional and safe for the parade.

Jill Wilfert, Senior Vice President, Entertainment Partners and Content at the LEGO Group, said: “We are excited to take fans behind the scenes of this incredible journey to the iconic, one-of-a-kind LEGO moment at the Miami Grand Prix. This showcase highlights the creativity and innovation that went into crafting these unique cars, as well as the excitement felt by both drivers and fans. We hope this special inspires F1 and LEGO enthusiasts to build anything they can imagine.”

The documentary was directed by Marcus Liversedge and produced by Auriol Wyles, with Leo Birch as creative director and co-executive producer for JustSo. Executive producers include Jill Wilfert, Keith Malone, Brent Benedetti and Robert May for the LEGO Group, and Jonny Madderson, Jono Stevens and Matt Shaw for JustSo. Stephanie Freeman-Kuflik served as associate producer for the LEGO Group.

The Miami project was part of the broader, multi-year partnership between the LEGO Group and Formula 1 to engage families and younger audiences through creativity and play. Following the Grand Prix, the ten LEGO F1 big builds embarked on a global tour under the “Build the Thrill” initiative, allowing fans to experience them up close at races around the world.
