Engine 2.4 litre V6
The Peugeot Nautilus concept by Pininfarina was based on a Peugeot 605. Pininfarina have designed other Peugeot vehicles, the best know is probably the Peugeot 406 coupefrom 1997.
The Peugeot Nautilus was not intended for production, more as a display of Pininfarina's ability to create a stunning four door luxury passenger car.
The Nautilus, designed by Ken Okuyama, used the sea for inspiration. The most obvious design elements to use this influence were the fin-like wheels and nautilus-shell shaped steering wheel center. Other interesting features included door handles hidden in the window frames and cameras instead of wing mirrors. http://www.diseno-art.com/encyclopedia/concept_cars/peugeot_nautilus.html
