Giotto Bizzarrini, the Italian engineer and designer who had a hand in the greatest Gran Turismos ever made, has passed away. He was 96.

Among many other sports and GT cars, Bizzarini was responsible for the development of the Ferrari 250 GTO, a racing and now collector car icon among the most sought-after objects in the collector world; he designed the V12 that would remarkably fit, among other places, transversely behind the seats and forward of the rear axle of the groundbreaking Lamborghini Miura; he created the Rivolta, Grifo A3/C, and Grifo Strada for Iso; and his own version of the Iso, the Bizzarrini GT Strada 5300 made by his own company.
