The gallery provides a glimpse into the process that begins with a rough sketch and eventually creates a full-scale mockup.

The secret design process that led to Tesla's new Roadster has been revealed in a series of images.

The Imgur gallery, spotted by BGR, starts with a rough sketch signed by Tesla's design chief, Franz von Holzhausen. It is unclear if the drawing represents an early idea that led to the final design, or perhaps simply an artistic reflection penned after the project was finished.

In any case, the sketch is an extremely close approximation of the full-size clay models used for a realistic mockup.

The Roadster's styling is certainly intended to attract attention, however its bold performance claims -- zero-to-60 mph in 1.9 seconds -- were the most amazing details presented at Tesla's semi unveiling.

The electric supercar is not expected to arrive in showrooms until 2020, with a price tag starting north of $200,000.
