Lamborghini Cabrera Rendered by AutoBild

We are all highly anticipating the arrival of the Gallardo successor which for the time being has been dubbed the Cabrera (still to be confirmed). The study model should show its face at IAA in Frankfurt and then the production model in Geneva next year. These latest renderings have been put together using the latest information and the latest spyshots. I am pretty confident the car will be a mix between the Gallardo, Sesto Elemento and the Aventador and thus I think the front of this rendering will be pretty close to what is produced. The rear on the other hand is not the prettiest sight I have seen and I highly doubt Lamborghini would do something so drastic to their biggest selling vehicle. What do you all think of these renderings?
