Yes, there are 4 classes in the current rules; and the DeltaWing was a fifth experimental class.
In the previous rules there were as many as 7 classes of cars on the track all at once, I think. In the past, there was as much as 100MPH difference in top speed, but now it is less than that. They introduced the chicanes in the Mulsanne Straight to slow the cars down after a few went airborne when they crested the rise... They were hitting speeds up to 380kph (236 mph) (the Longtail Porsche) and then the engines were limited. They were peaking at over 1,500HP...
The LMP1 are by far the fastest class -- they have LOTS of downforce and they can do the high speed turns at blinding speeds; though the GTP and GTA cars (the production based cars) have higher mechanical grip and are closer in speed in the slower turns.
