When Lamborghini introduced the LP500 at the 1971 Geneva Motor Show, it set the automotive world on fire and redefined created the supercar category. Marcello Gandini's work would stand the test of time, and lay the groundwork for every Lamborghini to come. The original LP500 was sacrificed in a crash test before the LP400's 1974 production launch, and in 2017, a very important Lamborghini customer asked if the LP500 could be recreated, and the project was launched. Lamborghini started with collecting blueprints and the building platform chassis from scratch — the production LP400 used a tubular space frame. Parts were sourced from Lamborghini's storage, refurbished, or built new, including the handmade bodywork. Pirelli recreated the Cinturato CN12 tires with modern compounds, using original drawings. What engine powers the LP500 wasn't mentioned, although the concept car used a five-liter V12 instead of the production LP400's four-liter unit. In all, over 25,000 hours were spent reconstructing the car. Watch the LP500 in action here.
