The Lamborghini Concept S is a concept car designed by Luc Donckerwolke, using the Lamborghini Gallardo's floorplan. Shown at the 2005 Geneva Motor Show. It was intended to be a modern interpretation of the single-seat roadsters of the past. Utilizing a 'saute-vent' (French for 'change wind') instead of a traditional windscreen, and dividing the interior into two distinct compartments by continuing the bodywork between the seats, which also serves as an air inlet feeding the mid-mounted 5 L V10 engine, gives the car a distinctly futuristic look. This is also to increase aerodynamic flow. The rear-view mirror is even electronically retractable to allow the driver to see behind, when necessary, or hide it when not in use. Though considered more of a styling exercise than a working production vehicle, the final working show car only had to be modified slightly from the original computer-aided designs. Lamborghini had rumored to be building 100 for customers, but decided to keep it as a styling exercise. Only 2 models were ever made: the high-window prototype sits in the Lamborghini museum with no engine, while the running low-window prototype featured at Pebble Beach is rumored to remain elsewhere in the factory.
