The prompt
Create a complete 3D CAD assembly of a compact front-engine, front-wheel-drive passenger car for an electric vehicle retrofit study. Include the full vehicle chassis, floor pan, front and rear suspension, wheels, steering, engine bay, passenger cabin, and underbody. Make the following components separate removable parts: 1. Petrol engine 2. Manual transmission/gearbox 3. Radiator 4. Fuel tank 5. Exhaust system 6. Front suspension 7. Rear suspension 8. Battery tray areas 9. Body panels and bonnet The engine bay must have enough geometric detail and clearance to allow the petrol engine to be removed and replaced with an electric motor and inverter. The chassis and floor should remain visible when the body panels are removed. Use realistic automotive proportions and mechanical mounting points. The goal is to use this assembly as a base model for designing a petrol-to-EV conversion, so prioritize the chassis, engine bay, drivetrain and underbody over exterior styling.
