This year marks the 50th anniversary of the Lamborghini Countach, the legendary supercar that inspired every current Lamborghini model. To celebrate, Lamborghini revived the Countach nameplate for a new limited-edition supercar based on the Aventador. Limited to only 112 examples, the reborn Countach combines vintage styling with hybrid tech borrowed from the Sian. But the celebrations aren't over yet.

Over the last few weeks, Lamborghini has been teasing a recreation of the original Countach LP 500 prototype that debuted at the 1971 Geneva Motor Show. 50 years later, the Countach LP 500 has returned.

The project started in 2017 when an "important Lamborghini customer" requested Lamborghini's Polo Storico restoration department to create a reconstruction of the Countach LP 500 prototype for the modern age.

After 25,000 hours of painstaking work, the reborn Countach LP 500 has debuted at the Concorso d'Eleganza Villa d'Este. To be clear, this is not a restoration of the original LP 500 prototype. After it stunned everyone at Geneva in 1971, the prototype was used in crash testing and was scrapped in 1973, so it couldn't be brought back from the dead. To recreate the LP 500 as accurately as possible, Polo Storico had to hunt down original photographs, documents, meeting reports, and original drawings.

The mechanical components were sourced from genuine spare parts and restored components, but some parts were completely rebuilt. Replicating the dimensions of the original LP 500 was also challenging. To achieve this, Polo Storico used a 3D scan of the original 1974 Countach LP 400 (chassis 001).

It then took 2,000 hours to painstakingly recreate the LP 400's striking wedge shape. The same technique was used to recreate the interior. The recreated LP 500 is finished in the same Giallo Fly Speciale yellow as the original prototype. Using images and materials provided by Pirelli, the team accurately replicated the Cinturato CN12 tires that were fitted to the original LP 500 in Geneva, sized 245/60R14 at the front and 265/60R14 at the rear. The tires even have the same tread pattern as the original 1971 car, updated with a modern compound and structure.

"The Countach reinvented high-performance cars and it became an icon in terms of stylistic language that even today, after decades, still inspires contemporary Lamborghinis," said Stephan Winkelmann, Chairman and CEO of Automobili Lamborghini.

"Bringing the reconstruction of the first Countach to the concept class of the Concorso d'Eleganza Villa d'Este, in the year we are celebrating the 50th anniversary of this model, is something extraordinary because it allows us to admire the legendary 1971 LP 500 in person for the first time in so many years."

No powertrain details have been released, but the original prototype was powered by a 12-cylinder 4971cc engine. The production Countach was underpinned by a tubular frame, but the prototype used a platform frame, which has also been recreated. Lamborghini hasn't said how much the collector paid to commission the reborn LP 500. But considering it's a one-off, we wouldn't be surprised if it cost even more than the $2.6-million modern-day Countach.
