Aspid GT-21 Invictus revealed – sort of

Aspid – the Spanish supercar maker which was IFR Aspid – has revealed the first images, and video, of the new Aspid GT-21 Invictus. IFR Aspid made the Caterham-esque – and rather bonkers – Aspid SuperSport, but after a change of name to just ‘Aspid’ they teased a new car back in May, which looked to be more mainstream. That tease arrives as the Aspid GT-21 Invictus, which takes the starting point of the very ‘open’ SuperSport and clothes it in a new body that turns it in to more of a GT car – even if it still gets open front wheels.
