Envision a highly detailed fusion between a Maserati Quattroporte and a Siberian tiger, titled 'Tigerati Supreme'. The vehicle should have the Maserati's sleek body but with the muscular build and powerful limbs of the tiger. It should be adorned with a fur-textured hood and sides, mimicking the tiger’s striped pattern. The wheels should resemble the paws, with the rims reflecting the intricate design of the tiger's print. The headlights are the tiger's eyes, luminous and piercing. This fusion is in motion, charging through a Siberian landscape that blurs around it, emphasizing the blend of speed and predatory grace.
