heavy-duty truck 3d model

A highly detailed, realistic 3D model of a modern heavy-duty semi-truck with a long cargo trailer (18-wheeler). The tractor unit (cab) features a sleek, aerodynamic design in metallic charcoal gray, with a detailed front grille, realistic headlights, and side mirrors. The trailer is a standard box/curtain-side model in a vibrant, deep purple color. The side panels of the trailer prominently display the 'accenture' logo in bold white lowercase letters, accompanied by the '>' symbol. The same branding is applied to the rear doors. The chassis is black with triple-axle wheels on the trailer and double-axle on the cab, featuring realistic silver rims and rubber tires. The geometry must be clean and optimized for industrial logistics visualization. High-fidelity textures with a professional finish. Ensure accurate proportions between the cab and the trailer length.
