产品视觉 GPT Image 2 提示词：Futuristic Audi Tron Concept Coupe

A futuristic concept coupe based on an {argument name="car brand" default="Audi"}, shown in a low rear three-quarter side view facing right, isolated in a vast black studio with a dark matte floor and almost no background detail. The car has a sleek white body with a long fastback roofline, blacked-out windows, an ultra-low stance, wide body proportions, and smooth minimalist surfacing. The side features 1 large pale gray swoosh graphic across the door and rear quarter panel, resembling a sporty decal. The rear is partially transparent or cut away to expose the performance drivetrain: 1 visible battery pack mounted low behind the cabin, 1 exposed metallic motor or transmission assembly, and 3 thick silver exhaust or intake pipes curving through the rear mechanical bay. The tail includes a continuous thin LED light bar spanning the width, the Audi rings glowing at center, and the word “tron” illuminated beneath. The wheels are deep black multi-spoke performance rims with low-profile tires; both visible tires have glowing white sidewall lettering, with stylized Japanese characters and racing text. Add subtle illuminated branding near the side skirt and front wheel arch. Lighting is cinematic and moody with cool blue rim light, glossy reflections, soft bloom, and a faint cyberpunk halo around the illuminated elements.
