Turn up the volume and watch as this elegant, yet monstrously powerful 1968 Sonny Levi “G.Cinquanta” G50 takes to the open water. The sensational “G. Cinquanta” was the product of the very latest in power boat engineering and design of its day. This example was commissioned by the much revered then President of Fiat, Alfa Romeo, Lancia and Ferrari, Gianni Agnelli, described by the press of his time as "the most elegant man on Earth". Federico Fellini wrote: "Put him on a horse and he will look like a king". With a brief that demanded the boat to be quick, reliable, and comfortable, and also able to negotiate mixed weather conditions, marine designer, Renato “Sonny” Levi, created the 37ft “G. Cinquanta” G50. Built to its exacting specification by Cantiere Delta, the craft features a luxurious cabin penned by Sergio Pininfarina, with power courtesy of four BPM 8.0-litre V-8 Vulcano engines, capable of taking the G50 to a top speed of 50 knots (92 km/h). There’s perhaps no more stylish way to arrive into the harbors of Monaco or Cannes.
