Project 35B

PROJECT OVERVIEW

This 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.

DESIGN INSPIRATION

Inspired by the iconic Bugatti Type 35, our mechanical car aims to capture the essence of artistic engineering and meticulous detail for which the original is famous. The Type 35 was a sculpture of speed, and our focus is similarly dual: we are emphasizing a clean, low-drag profile alongside aggressive, functional bodywork where no detail is purely ornamental. From the sleek bonnet to the tapering rear, the design prioritizes aerodynamic efficiency and mechanical clarity, echoing the Bugatti tradition of making even the internal components—such as the engine-turned dashboard or the exquisitely shaped exhaust manifolds—a visible work of art.

PERFORMANCE RESULTS

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.
