I don't know how much that is actually true to be honest. There's often a little bit of a difference as they try to get wheels and tolerances right, but I doubt it makes such a huge difference as we think, especially if the ride is well designed.
However, I completely disagree with Ethan and think the ride looks plenty fast enough. It looks faster than, say, a B&M mega but not quite as fast as an Intamin airtime machine. That's probably a good balance to be honest for this kind of "family" coaster Mack are producing. It will be "fun", which is sometimes all you need and I'll bet it's the kind of ride you can go on again and again without really getting bored, or struggle to deal with the extreme forces.
