IAD (International Automotive Design), a design consultancy based in the UK, introduced the Alien concept at the 1986 Turin Motor Show. The IAD Alien was a highly futuristic proposal for an advanced mid-engine supercar. The design highlighted the company's radical styling ideas and showcased innovative and unusual engineering solutions. Unfortunately, the car was a non-running prototype, so many were purely theoretical.
One of the more interesting ideas, if perhaps a bit over-complicated, was the modular construction method which meant that the rear-mounted engine of the car could be swapped out quickly and easily for upgrades, maintenance, or to suit the driver or different occasions! To access the interior traditional doors were dropped in favor of a one-piece canopy that tilted forward and provided almost unhindered entry and exit. Thanks to an integrated roll cage and sturdy side-impact bars, the passenger compartment was well-protected.
