The Ford Mustang Mach-E in Rocket League Sideswipe is a vibrant, cartoonish 3D model that captures the essence of the iconic electric SUV with exaggerated proportions for a playful aesthetic. It features a sleek, aerodynamic body with smooth, polished surfaces, bold racing stripes, and glowing LED accents that highlight its electric nature. The wheels are large and stylized, with detailed rims and low-profile tires, while the interior is simplified but includes recognizable Mustang design cues like the galloping pony logo on the steering wheel.
