Haribo Mercedes seems to be a little wider in the front compared to other 1/43 Carrera cars. This is one of the features of it being based off the AMG.
I have one other 1/43 AMG Mercedes and what they have in common is the suction they maintain around the track. While they won’t fly off the track the suction kind of slows them down. I don’t know if it’s the magnet or the wing that creates the suction.
