The quest for simplicity comes to life with this car. I wanted the 3D model to be so detailed that, if it were 3D printed, it could actually function. The project is still in progress, but it is already at a stage where the car could start and drive, only missing the body and a few additional features. 

My Thinking

To create a working car in CAD, it needed to be simple to design and build. My first step was planning the simplest engine possible, one with the fewest moving parts and the easiest concepts to understand. I concluded that a two-stroke engine was the best choice because it’s incredibly straightforward and easy to grasp. I also wanted the car to be powerful, since its target market is younger drivers. That meant adding more cylinders, and after comparing simplicity and power, I decided that two rows of three cylinders geared together would be ideal. From there, I kept the other major components just as simple. The engine is air-cooled with a basic fan, uses mechanical pumps, magneto ignition, a sequential transmission, and a helical differential. Each of these parts not only has minimal moving components but also serves a clear, understandable purpose. This makes the car easy to model accurately and to comprehend conceptually. Now any car enthusiast with basic mechanical knowledge could understand exactly how every part of their car works, something not seen since the Volkswagen Beetle. Repairs could take minutes, and reliability would be exceptional. 

ABOUT

Overall Design:
Classic rally car proportions with rugged, practical styling.

Layout:
Mid-engine, air-cooled 2.0L two-stroke “double three” engine paired with a five-speed sequential transmission. The drivetrain features full-time selectable 4WD, a locking center differential, and helical front and rear differentials.

Suspension:
Four-wheel independent double-wishbone suspension with equal-length half-shafts and coil-over shocks, accompanied by unassisted disc brakes.

Performance:
0–60 mph in four seconds, producing 220 horsepower, with near-zero electronics and minimal moving parts.

Cost:
Sold as a complete car in Europe for $30,000, or as a kit car in Europe and the U.S. for $28,000. Limited production of 200 units or fewer per year.
