They should also add GTA IV TLAD vehicles in a different section. GTANet has to finish up the new list already (nothing in the aircraft section).
However, the Infernus does look like the fastest vehicle in the game, and it for surely looks faster than the Coquette. Maybe this list is more accurate, but it kills me to know that for a long time that everybody believed the Infernus was a bit faster than all other land vehicles (with faster acceleration) and now that is said to be wrong. On the old list, the Coquette I believe was said to go about 180-195 mph or something like that.
When they had that, the fastest vehicles in the game went up to 208 mph (the Comet goes basically 215 mph with the new list) with the Infernus having the fastest acceleration out of land vehicles. I remember on when they had the old vehicle list (drop-down list with pictures to go along).
