In 3 days Lamborghini will unveil something very unique at the 2012 Geneva Motor Show. This is their traditional release venue for new cars and concepts. They released the video clip below as a teaser with the tagline – Unica. This could simply come to be known as the Unica Concept or the Lamborghini Aventador J. There are some leaked images floating around of a topless Aventador that we believe to be the car. This will not be the production version but will reflect the spirit of the actual 2013 Lamborghini Aventador Roadster that we saw spy shots of recently. This is consistent with their strategy in unveiling the 2005 Lamborghini Gallardo Spyder concept in 2005, pictured below.
