Someone Built A Miniature Audi 100 With A Working Engine And It Rips

The world of remote-controlled cars isn’t just for casual backyard fun anymore. Thanks to advancements in miniature engineering and obsessive craftsmanship, RC cars have become an entirely different breed—especially when someone goes as far as building a complete drivetrain from scratch. One recent YouTube build took this to the extreme, recreating a fully functional, scale-sized Audi 100 Coupé S that not only runs but also features a working clutch, transmission, suspension, and even power steering.
In a step-by-step showcase that feels more like a watchmaker assembling a Swiss timepiece than someone fiddling with toys, the builder behind Makerium walks viewers through every part of the process. This isn’t a plastic shell with a battery pack—it’s a tiny, high-revving tribute to mechanical purity, dyno-tested and track-ready in 1:10 scale.

This RC Audi Build Starts With A Real Engine

The project kicks off with the careful assembly of a working miniature internal combustion engine. That includes a starter motor, flywheel, pressure plate, and even a custom-built clutch disc. This isn’t just a model that looks good—it cranks over and fires up like a proper performance motor, even if it’s smaller than your fist.
From there, the builder moves to the transmission, grinding and installing every gear manually for perfect fit and meshing. The gears are installed on main and countershafts, then sealed in a housing with precision bearings and gaskets. An electronic servo system is added to shift gears remotely, just like paddle shifters in a full-sized performance car. And yes, the entire powertrain is dyno tested for power delivery and responsiveness.

This Tiny Audi Hot Hatch Was Faster Than A Nissan GT-R

A rare Audi hatch once outpaced a GT-R on track. Small in size, big on performance – this forgotten gem proved speed isn’t just about horsepower.

Why This Tiny Audi Has Real Suspension, Brakes, And Power Steering

To make this scale replica perform like a true enthusiast’s car, the builder didn’t stop at just the drivetrain.
Highlights Of The RC Build

The RC Audi gets a fully functional independent suspension setup front and rear.

Real control arms, knuckles, subframes, and dampers ensure smooth motion over surfaces.

Hydraulic-style brakes are installed with fluid lines, brake supports, and bleed points.

The car even features electronic power steering for precise control and less effort.

High-performance RC tires and hubs are tested for grip and cornering stability.

Audi’s Hottest New EV Isn’t Coming To America — And That’s What Makes It So Tempting

Audi’s newest EV isn’t just about power and range — it’s a sharp-looking, China-exclusive fastback that kicks off a bold new chapter for the brand.

All of this is installed and then fine-tuned through functional testing. Steering, suspension, and braking mechanisms are checked for full articulation and response. The final touch? A flawless body finish mimicking the original 1969 Audi 100 Coupé S—complete with primer, paint, and a polished look that mirrors the car’s vintage character.
