Named for a Titan in Greek mythology, the Pininfarina-etched Hyperion from 2008 was designed to evoke memories of cars from the 1930s with its long majestic bonnet, short rear overhang and low rooflines. Based on the Rolls-Royce Drophead Coupe, the changes needed to create the Hyperion included the removal of the rear seats and a shift in driving position, which is now 400mm further back in the Hyperion than in the Drophead.

If this sounds appealing to you, the bespoke one-off vehicle is actually up for sale on luxury goods website Jameslist, but before you get too excited not that pricing will set you back a cool 4,500,000 euros. For that kind of money, however, you’re not just buying a car, you’re actually buying a piece of history, as well as a unique Girard-Perregaux wristwatch.

The Hyperion was designed by the Special Projects division of Pininfarina, which also created the one-off Ferrari P4/5 a couple of years ago for James Glickenhaus. The Hyperion was designed for Rolls-Royce collector Roland Hall, who made specific requests for the cars appearance and utility - including two compartments for small items such as hunting rifles, located in front of the windscreen.

The standard Drophead coupe features a 6.75-liter V-12 engine developing a peak output of 453hp (338kW) and 531lb-ft (720Nm) of torque, which is enough for an electronically limited top speed of 155mph and a 0-60mph sprint of just 5.6 seconds. No major mechanical changes have been installed for the Hyperion.

Delivery is scheduled for September.
