What a machine. Styled by none other than Ian Callum, who now works for Jaguar...
Speaking of 90s endurance racers, and Lamborghini for that matter, meet the Konrad KM-011!
This was the result of a brief partnership between Konrad Motorsport and Lamborghini. Konrad were more accustomed to running privateer Porsche 962's, so its designer Franz Konrad essentially reworked that car to create this. It was then powered by a Lambo 3.5l V12, though powered figures are hard to come by, as are almost any other details about this car.
You can really see the similarities to the 962 here with the bubble cockpit and the gentle curve dip along the side of the car.
Sadly however, it didn't do well, and was plagued with a lack of competitiveness and reliability issues. Hence, it only appeared for the 1991 season of the World Sportscar Championship.
