LEGO Turns Shanghai’s Subway Into a 4,104-Piece Celebration of Engineering

To launch the LEGO Technic Koenigsegg Sadair’s Spear, the brand transformed Shanghai Metro stations into immersive installations, displaying every single piece used to build the 1:8 scale hypercar

LEGO has taken over two of Shanghai’s busiest metro stations to launch its newest — and largest — Technic supercar, mounting all 4,104 individual pieces of the set inside subway lightboxes rather than relying on a single finished model to sell the story. The campaign, which spans West Nanjing Road Station and Lujiazui Station, was built around the idea of making engineering excellence visible and buildable rather than leaning on traditional advertising formats.

Piece by Piece, Not Just the Finished Build

The two stations tell the story differently. At West Nanjing Road Station, four sequential installations walk commuters through the engineering behind the car — starting with its 1,625-horsepower twin-turbo engine and Koenigsegg’s nine-speed Light Speed Transmission, moving through the Triplex suspension system and aerodynamic bodywork, before culminating in the completed model At Lujiazui Station, four large-scale installations lay out all 4,104 pieces alongside the finished build, giving riders a literal, physical inventory of everything that goes into the set before they ever see it assembled.

It’s an unusual choice for a toy launch — most car-set marketing shows off the finished product and lets the box count speak for itself. Displaying the raw components at station scale instead treats the parts list itself as the spectacle, leaning into what collectors already love about Technic builds: the sense that a working machine, not just a static model, has been engineered from scratch.

The Car Behind the Campaign

The set at the center of the campaign is 42232 Koenigsegg Sadair’s Spear, the sixth and largest entry yet in LEGO’s Ultimate Car Concept Series. <cite index=”26-1″>At 4,104 pieces, it is the biggest set the series has produced since the line launched in 2016, and LEGO describes it as the most advanced Technic build it has ever created. The model includes a working V8 piston engine driving a functional drivetrain, plus two firsts for the series: a nine-speed functional transmission with a rotating gear-indicator disc, and Triplex suspension front and rear It also features a working steering system, a removable roof, and measures 59 cm long, 28 cm wide and 15 cm tall once built.

The standout mechanism is what Koenigsegg calls Ghost Mode. A single motion simultaneously raises the rear clamshell, rotates the doors open, lifts the hood and folds in the mirrors — recreating the theatrical door sequence of the real car. In LEGO’s own build, lifting the model’s rear clam engages the same sequence, with the doors, hood and mirrors sweeping open in one smooth movement.

The real Koenigsegg Sadair’s Spear that inspired the set is itself vanishingly rare. Only 30 examples of the car exist in the world, and it’s a high-performance variant of the Koenigsegg Jesko, with its name honoring a horse that Christian von Koenigsegg’s father rode as a jockey The set follows LEGO’s biennial release pattern for its 1:8 Ultimate Car Concept line, arriving two years after 2024’s McLaren P1, and joins previous entries built around the Porsche 911, Bugatti Chiron, Lamborghini Sián and Ferrari Daytona.

A Life-Size Stunt to Match the Scale of the Campaign

The Shanghai installations weren’t LEGO’s only oversized gesture for the launch. To mark the release, the company built a full-scale, drivable version of the Sadair’s Spear entirely out of LEGO elements — 327,906 pieces in total, weighing roughly 1,800kg. Of that weight, about 400kg came from the LEGO elements themselves, and the build took more than 9,400 hours to develop and construct.

That car wasn’t just for display. Koenigsegg test driver Markus Lundh drove it down the Goodwood Hillclimb at 111km/h, more than doubling the previous LEGO Technic speed record of 50km/h set the year before. Reflecting on the run, Lundh said driving the life-size brick car felt like handling a real Koenigsegg.

Koenigsegg’s chief operating officer, Halldora von Koenigsegg, framed the partnership as a natural pairing of two engineering-obsessed brands, noting to The Race that both companies have people with an “obsession for innovation,”</cite> which she said made the collaboration a fitting match. She also pointed to a detail built into the real Sadair’s Spear —an inscription reading “when imagination meets innovation” as a fitting nod to the LEGO tie-in.

Availability and Pricing

The set goes to LEGO Insiders for early access starting July 1, 2026, with general release following on July 4. It’s priced at €449.99, £399.99 or $449.99, and is rated for builders 18 and up. Anyone who orders between July 1 and 6 will also receive the exclusive 40894 Koenigsegg Sadair’s Spear Steering Wheel as a gift with purchase, while supplies last.

Why It Matters

The Shanghai campaign is a reminder that LEGO’s marketing playbook for its flagship adult sets increasingly treats the build process itself as the product story, not just the finished object on a shelf. By scattering thousands of individually mounted pieces across two of the city’s transit hubs, the brand turned a routine commute into a piece-by-piece argument for why a 4,104-part hypercar model is worth the engineering obsession — before a single brick has been clicked into place.
