Yeah that's right because they are totally different vehicles, so it's not fair to compare. Their actual 0-100 time is more or less the same.
In real world, CL9 has much more power, but hampered by sluggish auto with "tall" gearing and peaky power delivery which means it's a slow starter. Vezel is opposite with much less power, but benefits from DCT and instant hybrid power which yield great results in start. Meaning Vezel has advantage in standing start and short races, but impromptu races are hardly standing start and hardly end at 100.
