Suppose it is the XO1's in the new truck.
The X01 motor is otherwise known as the Castle 1717. Very nice motor, no doubt about it. I have one in my SuperMaxx and it's missile fast - nearly uncontrollable unless you have a very light touch on the trigger.
That's an 11lb RTR truck.
You bump that up to 20lbs, make the tires 50% bigger and....eh, maybe not so impressive I think.
But, put the power setup I've got in my 5ive (12s MGM & Lerner = 20hp) in there and now we'd have something.
I'm eager to see this new Maxx, but I don't anticipate being overwhelmed by performance. How it's drivetrain holds up to 20hp will be interesting to see
