It seems like a single cylinder 200cc big bore engine, cos would need quite a bit of torque to move with 4 people. It probably was a good choice as if it was a twin cylinder, it might not have been that torquey, anyway, it lasted for 10 years!!!
But apparently it is still in one piece and is being restored (The original blog where i got the story from, says "The car is in pieces now, as it is in the initial stages of being restored by AO & KO. The color is going to Ferrari red, as it used to be when originally made."
