I guess the concept artist based his work on a morgan roadster but I don't find similar systems on their models.

So I'm asking if anyone know something about this car structure or even redirect me towards picture of the right model/drawings, I'd be glad because I'm hitting a wall on this work right now haha. I don't have enough car knowledge on those type of cars.

Many thank for your attention
