4. Cizeta-Moroder V16T (1991-1995)
The Cizeta-Moroder V16T stands as one of the most exotic supercars ever built. Developed by Claudio Zampolli and music producer Giorgio Moroder, this Italian rarity featured a unique transverse-mounted V16 engine—a world first. Its bold styling drew comparisons to the Lamborghini Diablo, but underneath, the V16T’s engineering was even more audacious. With just a handful ever produced, it remains a cult classic among collectors and enthusiasts.
