The Colani L’Aiglon was a concept car built by Colani in 1976.

It was Colani's first roadster with a retrodesign.

It used the front axle from a Rolls-Royce Silver Cloud and the V8 engine (including the camshaft) from an Opel Diplomat. A Rolls Royce radiator and Opel GT roof were applied, and in 1976 a white example was shown at the Geneva Motorshow.

The car looks a lot like a flattened and lengthen Auburn Boat-tail Speedster with the exhaust pipes coming out of the side on the engine bay and large flared wheel arches. A luxurious interior helped to compliment the wild looks of the car.
