Brick Leon / Laoliang MOC 03 Showcase
Brick Leon / Laoliang MOC 03 uses a new third-generation gearbox layout with about 50% less volume than the 42172-style third-generation gearbox, while improving transmission efficiency and shifting reliability.
8-speed dual-clutch sequential transmission
Includes paddle and rotary shifting, hybrid/DNR simulation and a dynamic visible gear indicator.
Linked steering, engine and suspension motion
Driving motion links to the V8 engine, while steering can connect with suspension roll behavior.
Opening bodywork with strong shelf presence
Spring-assisted gullwing doors, opening covers and raised aero details create a high-impact creator visual.

MOC 03 / Product introduction
Mechanical and Build Highlights
The official introduction centers on the real third-generation gearbox, dual-clutch shifting, DNR simulation, kinetic-energy recovery simulation and linked suspension/aero behavior.
True third-generation gearbox
The third-generation gearbox was redesigned as a new solution. Compared with the third-generation gearbox used in 42172, the MOC 03 gearbox is reduced by more than 50% in volume while greatly improving transmission efficiency and shifting reliability.
8-speed dual-clutch + hybrid + DNR + energy recovery
The model recreates an eight-speed dual-clutch sequential gearbox concept, with simulated motor behavior, simulated electronic reverse and simulated kinetic-energy recovery.
Dual-channel shifting
In addition to active shift paddles, MOC 03 includes an extra shift control, giving creators more mechanical interaction points to demonstrate.
Dynamic navigator-style instrument panel
The dashboard works as a visible gear-position indicator, allowing the current gear state to be seen at any time.
Driving motion and V8 engine linkage
The driving motion links to the V8 engine, giving the model a clear mechanical relationship between wheel movement and engine behavior.
Steering wheel and suspension roll linkage
The steering system links to the cockpit steering wheel, while steering can also drive visible suspension side-tilt movement and roll-steering behavior.
Pushrod front suspension with rocker arms
The front suspension uses a pushrod layout with rocker arms, paired with a third horizontal shock absorber structure inspired by the real car.
Rear double-wishbone suspension
The rear suspension uses a double-wishbone concept inspired by the real car, adding strong technical interest for close-up review shots.
Independent front/rear ride-height adjustment
Front and rear suspension height can be adjusted independently, supporting a richer mechanical demonstration and more expressive display stance.
Front splitter and rear diffuser linkage
The front suspension lift links with the front underbody splitter, while the rear suspension lift links with the rear diffuser for an integrated chassis/aero effect.
Spring-assisted gullwing doors and opening covers
The model includes spring-assisted gullwing doors, opening front and rear covers and a fully removable engine cover for strong display and filming moments.
Large-module assembly and rigid body
MOC 03 is designed with easy-to-assemble large modules and a solid full-vehicle structure, making the build clearer, more reliable and easier to present.
