The Diatto GT Ottovù may not have topped our list of hottest concept cars at the Geneva auto show this past year, but those who can see past a few dated swoops of the pen will soon be able to snag one of 99 units to be produced. The revival of the Diatto brand is a milestone for Italian motoring — that brand being one of the country's oldest — and Zagato's design plays it to the hilt. The metallic-green Diatto GT Ottovù prototype was unveiled in Geneva and subsequently at the Villa d'Este Concorso d'Eleganza (gesundheit). Power comes from a Ford-sourced 4.6-liter V8 jointly tuned by Roush and Cosworth. It produces 530 hp in base form, but a few undisclosed tweaks will bring it to 650 hp. The new Diatto is building a dealer network in the US and Europe. No word on price, but there's no doubt the usual suspects will step up, checkbook in hand. [Italiaspeed via AutoBlog]
