Well its real life physics, ill try my best to explain. The car behind gains the benefits of reduced air resistance and decreased drag. This results in better fuel economy (not sure if thats in forza but it might be due to some races i have run where the spec cars ran out of gas at different times) and also increased speed. The car ahead gains minor drag benefits and does infact gain some speed however, the air resistance is still present which is why the car in tow is faster. Well, that and there is an interesting pulling motion that the air around the lead car creates. The air leaves a small vacuum where the car in tow can position itself, the direction of the air then pushes the car down and forward. Race car physics are very interesting.

How does the lead car gain a benefit?

The lead car does not have any drag. Drag is the air that is pushed around the car by the car. It pulls the car hence "drag". The rear car takes the drag resistance while the lead car takes the air resistance. Think of it this way. You are pushing a boulder while someone is pulling on your shit from behind. You have two forces to deal with, pushing and pulling. When two cars work together the lead car pushes, and the rear car pulls.

So in layman's terms, the rear car cancels the drag caused by the lead car?

Yes.

And the range that you can draft at increases with speed?

Indeed, i assume its some kind of hyperbola-like graph, maybe exponential.

Who knows? Google it,

Basically when you draft the air is hitting the front of the car in front of you and is hitting the front of your car less. The air is like an elastic cord that onky letting you get to for example 160mph then with less hair hitting the front of your car as you go along its like the elastic is legging slackened to let you go faster, the closer you follow the car in front the faster you go

I've had races where I snagged a slipstream at 190 MPH and then went flying past the lead car at 220 MPH on Sarthe. AThe car was quite some distance away. maybe 19-20 car lengths.

goooooood luck with that search. the mess of graphs would be mind boggling. but we digress.

So...any of you guys have PBs in the 4:40s with C class?

This should section of this post should be split, moved, and renamed the science of drafting.   

whats offlimits for c class? as in leaderboard?

I think whatever everyone in the top 10 uses lol
Also no forza aero

i never even looked lol ill make a few and hope at least one isnt a lb car

Try the VW Corrado.

4:38.488 in the MR-S

I can't believe I was asleep during the whole drafting conversation but Sainted did a good job to explain it.

It's unnoticeable on Kaido but on Nurburg or Le Mans the lead car can gain 2-3mph if someone is drafting close behind on a straight. Air resistance is a funny little bugger.

Take a look at the LB, Like B class, 90% of the top 100 is lotus elises. I think the Elan is big in C class

^D class. It's a D-class thing. the Spark is LB in F-E.

The Lotus Elan IS the LB car of C class.

Well, I'm not entirely wrong then. XD

4:42 C-class AE86

._. that's impressive

ill just go ahead and sell that elan then (there goes my cuppaccinno...)
