The Rockstar Games blog mentioned, “Significant work went into creating this real world version of the 2013 model featured in Grand Theft Auto V. Utilizing state-of-the-art fabrication technologies, molds for the exterior were cut and machined piece-by-piece for the high performance base vehicle. With these molds each panel was laid out by hand to create an entirely new exterior resulting in a screen accurate reproduction of the Banshee.”
It is through the use of referencing both model and textures of the in-game car that the interior was specially handcrafted and stitched together, in order to capture the look and feel of its cockpit. Both seats have been upholstered and embroidered with the Banshee name and insignia to add that extra level of realism.
