Lamborghini has published a new promo video for the 2012 Aventador called ‘Quality’ in which it presents a few scenes with what it takes to make the Murcielago replacement one of the best supercars on sale today.
The footage starts with a white drawing sheet and ends with two Aventador exemplars having fun on public roads.
We also get so see some in-between stages, like sketching the car, developing it using computer design tools, creating a small scale version of the car, choosing the right materials and components, fabricating body and engine components, assembling the interior and more.
