brave-bmw System Requirements Document

Introduction

The "brave-bmw" project is a premium, high-fidelity full-stack web application dedicated to showcasing the entire history, present, and future of BMW. This application will feature an interactive virtual custom car garage, providing users with a sophisticated, minimalist luxury design experience. The design will incorporate a Deep Black, Dark Grey, and White color palette, accented with classic BMW M-Sport colors for interactive elements and state tracking.

System Overview

The brave-bmw application aims to engage BMW enthusiasts by offering a comprehensive platform that highlights BMW's legacy and future innovations. Users will be able to explore historical data, configure custom vehicles, and save their creations in a personalized garage. The application will be built with a focus on luxury, performance, and user interaction, reflecting BMW's brand values.

Functional Requirements

• As a User, I should be able to navigate seamlessly between the historical timeline, live showroom database, custom configurator, and my garage.
• As a User, I should be able to explore an A-to-Z historical database of BMW's eras, with real-time text filtering and category tabs.
• As a User, I should be able to configure a custom BMW using the "BMW Custom Studio" with options for model selection, exterior paint, wheel designs, interior upholstery, and performance packages.
• As a User, I should be able to save my custom-configured BMW to "My Saved Garage" and manage my saved configurations.
• As a User, I should experience a luxury-focused tone and subtle hover animations throughout the application.

User Personas

• Guest User: Can explore the historical database and use the configurator but cannot save configurations.
• Registered User: Can save and manage custom configurations in "My Saved Garage" and access personalized content.

Signature Design Concept

The brave-bmw homepage will feature an interactive 3D virtual showroom using @react-three/fiber and @react-three/drei. Users will navigate through a virtual BMW museum where each section represents a different era of BMW's history. As users scroll, the showroom dynamically transforms, showcasing iconic models in lifelike detail. Interactive elements will include clickable car models that reveal detailed specifications and history. The configurator will allow users to "build" their car in this virtual space, with real-time updates and animations.

Interaction Model & Motion Direction

The landing page will use a "parallax" interaction model, creating a layered depth effect as users scroll through the BMW timeline. Each section will have distinct interactive mechanics, such as 3D car models that rotate and animate on hover, and dynamic content reveals triggered by scroll position. Internal pages like the dashboard and settings will use a "static" model for clarity and ease of use.

Non-Functional Requirements

• The application must load within 3 seconds on a standard broadband connection.
• The system should handle up to 10,000 concurrent users without performance degradation.
• Ensure cross-browser compatibility for Chrome, Firefox, Safari, and Edge.

Tech Stack

• Frontend: React for Web
• Backend: Python, FastAPI
• Database: MySQL or MariaDB, with alembic for migrations
• AI Models: GPT 5.4 for user-friendly responses
• AI Tools: Litellm for LLM Routing
• Local Orchestration: Docker, docker-compose
• Server-side Orchestration: Kubernetes

Assumptions and Constraints

• The application will primarily target users in India, with localization for Indian English.
• The system will assume a standard user timezone of IST (Indian Standard Time).
• The application will be optimized for desktop and mobile web browsers.

Glossary

• BMW M-Sport Colors: A set of colors traditionally associated with BMW's motorsport division.
• Configurator: A tool that allows users to customize and build their own car model.
• Parallax: A scrolling technique that creates an illusion of depth by moving background images slower than foreground images.
