Motorized V12 Supercar Engine Model STEM Building Block Set

Twelve cylinders. One unforgettable build. The KAIXING K96211 is a precision-engineered, motorised, app-controlled replica of the most legendary engine configuration in supercar history - the V12. Styled after the power plants found in the world's most exclusive supercars, this is not a box of blocks. It is a working mechanical masterpiece you assemble piece by piece, system by system, until it roars to life in front of you.

With 1,610 high-precision ABS pieces, you will construct every major component of a real internal combustion engine - the crankshaft and twelve pistons, the valve train, the timing chain, the intake and exhaust manifolds, and the drivetrain. The transparent cylinder head with its unique valve mechanism means nothing is hidden: watch the valves open and close in sequence, follow the pistons as they fire, and trace the simulated mechanical chain drive system as power flows through the engine exactly as it would in a real V12.

And this engine doesn't just sit there looking beautiful. Connect your phone via Bluetooth and take full command through the dedicated app - a live speed display, adjustable throttle, and a programmable interface whose layout you can customise for even more playability. Shift through the working three-speed transmission - first, second, third - while authentic engine audio swells with every gear change and fades naturally as you decelerate. Activate the LED lighting and the engine bay glows with a rich red light beneath the carbon-fibre-look covers. Then add water to the reservoir, fire up the spray module, and watch realistic vapour pulse from the side-mounted quad exhausts as the engine runs.

Finished in a striking race-inspired red, black and silver colour scheme with braided silver intake lines and a drilled brake-style flywheel disc, the K96211 is as much a display sculpture as it is a build project. Whether you are a young engineer discovering how engines work, a petrolhead who lives for mechanical detail, or a collector hunting a centrepiece with genuine presence - this is hands-on learning, engineering appreciation and show-stopping craftsmanship in one unforgettable package.

Key Selling Features:

1. 1,610 High-Precision ABS Pieces for a Premium Build Experience:

Every component is manufactured to a tight tolerance, delivering a perfect fit and a smooth, frustration-free building process where each completed stage brings a genuine sense of accomplishment. The full step-by-step instruction manual guides builders aged 6 and up through the entire assembly, with adult assistance recommended for younger enthusiasts.

2. Working Three-Speed Transmission:

Shift 1st, 2nd and 3rd gear from the app - Unlike simple motorised models, the K96211 simulates a real gearbox. Run through first, second and third gear via the app controls and feel the engine's character change with every shift - an extra layer of realism that engine lovers will genuinely appreciate.

3. Customisable Mobile Programming Module Interface:

The companion app's layout can be freely rearranged to create more playability. Set up the controls exactly how you like them - throttle, sound, lights, mist and gears - for a personalised command experience every time you run the engine.

4. Authentic Engine Sound that Responds to your Throttle Input:

The start-up sequence, idle note and acceleration roar are modelled on a real V12, and the sound gets louder and more intense as you accelerate - then decreases naturally as deceleration occurs. It is an immersive audio experience that puts you in the driver's seat of a supercar power plant.

5. Transparent Cylinder Head with a Unique Working Valve Mechanism:

Most engine models hide their internals. The K96211 celebrates them. The clear cylinder head lets you observe the unique valve mechanism operating in real time, offering an unmatched window into how a real V12 breathes.

6. Simulated Mechanical Chain Drive System with Moving Pistons and Gearing:

Power flows through the model exactly as it does in a real engine. The timing chain, crankshaft, pistons and gear trains all rotate and mesh in sequence, making the complete power delivery cycle visible and easy to understand - a hands-on engineering lesson built into every rev.

7. Realistic Exhaust Mist Effect:

Just add Water - Fill the built-in reservoir, activate the spray combination module and watch as fine vapour pulses from the quad side-mounted exhaust tips while the engine runs. It is the showpiece feature that transforms this model from a static display into a living, breathing machine.

8. LED Lighting Brings a Richer Visual Experience:

Integrated LED lights glow beneath the carbon-fibre-look engine covers and along the transparent block, illuminating the moving internals with a rich red light - especially dramatic in low light. A display piece that looks as impressive at night as it does during the day.

9. Motorised Master Control Box with Large-Capacity No. 5 (AA) Battery Power:

The included master control unit drives every function - motor, sound, lights and mist - from a single No. 5 (AA) battery box with large capacity and strong endurance, so you can enjoy extended running sessions without constant battery changes.

10. Race-Inspired Red, Black and Silver Finish with Authentic Supercar Detailing:

From the carbon-fibre-look covers and braided silver intake lines to the red coil springs, gold accents and drilled brake-style flywheel disc, every visual element replicates a genuine high-performance V12 - a collector-grade display piece that draws the eye from across the room.

11. High-Fidelity STEM Learning Disguised as Pure Fun:

By faithfully simulating the structure of an internal combustion engine - piston linkage, valve timing, gearing, transmission and chain drive - the K96211 teaches real mechanical principles through play. It builds problem-solving skills, patience, fine motor control and engineering curiosity, making it as valuable an educational tool as it is an entertaining build.

Why You Need This:

Some purchases you forget about within a week. This is not one of them.

The KAIXING K96211 V12 is an experience in three acts. Act One: The Build. Across hours of focused, satisfying assembly, you construct one of the most revered engine layouts in automotive history - piece by piece, system by system - with high-precision parts that fit together flawlessly. It is the kind of screen-free, hands-on project that builds patience, confidence and genuine mechanical understanding, whether you are 6 or 60.

Act Two: The Reveal. The moment you pair your phone, press start and hear that V12 wake up for the first time is genuinely spine-tingling. Shift into first, then second, then third - the sound swells with every gear change, the chain drive spins, the red LED glow ignites beneath the covers and vapour bursts from the quad exhausts. Guests will stop mid-sentence. Kids will fight over the throttle. It is part science demonstration, part magic trick.

Act Three: The Display. Long after the build is complete, the K96211 keeps earning its place in your home. With its race-red block, carbon-fibre-look covers, braided silver intake lines and unmistakable supercar presence, it looks like it was lifted straight from an exotic car workshop - a conversation-starting centrepiece for an office, study, man cave or collection shelf.

And when it comes to marking a special occasion - a birthday, Christmas, Father's Day, a graduation or a well-deserved treat for yourself - few things make a more memorable statement than a machine that must be built, understood and mastered before it can be enjoyed. The K96211 isn't just a model. It's hours of engagement, a lifetime of display value, and a story the recipient will tell every time someone asks, "Where did you get that?"
