Giotto Bizzarrini was a former Ferrari executive and freelance designer. In addition, Bizzarrini worked with Lamborghini, designing their legendary V12 engine, and for Iso, where he developed motorbikes and cars. Among his first projects was to design the Grifo, based on a shortened Iso Rivolta chassis, retaining the original car’s running gear. Bizzarrini saw potential in the Grifo and obtained permission from Iso chairman, Renzo Rivolta, to manufacture a high-performance version under his own name. This was suitably named the Bizzarrini 5300 GT Strada, and was available to the public from 1964.
One of my favorite cars of all time!
