Repeatable mechanically powered car — no electricity, only pure mechanical energy.
WATCH THE DEMONSTRATIONThis project explores the design and development of a car powered entirely through mechanical means. The car is engineered to store and release energy using springs, gears, and flywheels — achieving repeatable motion without any electrical components. The goal is to demonstrate efficient energy transfer, stability, and control purely through mechanical systems.
This challenge pushed the team to apply core principles of mechanical engineering, focusing heavily on friction reduction , optimal gear ratio , and chassis stabilisation under high strain, mirroring the real-world demands of high-performance automotive design.
The aesthetic and performance focus for our mechanical car is inspired by the iconic Porsche 911 930 Blackbird , emphasizing a low-drag profile and aggressive, functional bodywork, complemented by specialized BBS wheel geometry for minimal rotational resistance.

The prototype successfully demonstrated multiple repeatable runs powered purely by stored mechanical energy. Key performance indicators met or exceeded initial stability requirements.
Further optimizations in gear ratio selection and friction reduction are expected to improve the maximum achievable distance and energy efficiency in subsequent iterations.
