For reasons beyond TopGear.com's comprehension, lots of hypercars congregated at the Shanghai F1 circuit recently. For this kind of occurrence, we don't require ‘reason'.

During the course of your watching/breathless panting/inexplicable heart palpitations, see if you can name all of the cars in the video. Winner gets... a hearty pat on the back from us, sent via Internet.
