Axle hop usually occurs when the pinion angle rotates up due to some kind of deflection in the suspension. When the deflection ceases, the pinion snaps back to its normal position, which causes the tire to break traction and hop. It requires a large amount of torque to be suddenly applied. You usually see this on cars with leaf springs.
For your car, it's probably caused by too much traction or an over-assertive ESP. If the brakes are applied too hard during hard acceleration, axle wrap could occur and cause the pinion to rotate. Of course, this is just speculation on my part - I could be wrong.

My blown W210 did the same thing, but it was almost always because of some difference in the surface the tires crossed as they were spinning. Just the slightest hiccup out of ESP and the bounce would start. Perfectly smooth and even surfaces almost never caused wheel hop. If it happens often, keep an eye out for the triangle flash.

211 E55(sold) & 80cc shifter kart
i had axle hop bad and it was caused by a rear left shock that was blown, when i took it in they replaced both shocks cause the other one was leaking.
after new shocks no more hop.
after new shocks no more hop.

Hop is not right in these cars. As Grumps said, it would come from great traction or something broken. The rear suspension basically acts as a power soak when you punch it. It absorbs that power then transfers it to the ground. If shocks, etc were broken then you would definitely get the hop. Also any worn bushings, etc would do that. If all is right AND you simply have a modif9ied car with great traction (i.e. fat tires and LSD), then consider Toe Links.

I had hop and was freaking out, but it came down to me launching on a stretch of road with some ashpalt patching compound. Not sure what actually happened but have launched dozens of times since on other surfaces without a hitch.
You getting hop a lot or was it the one time. Pretty dramatic eh? Sounds like the rear is about to fall off. When you think of the torque required to do that with our boats, it is incredible.
