What "class" would that be? Small car class?
Exactly what facts are you talking about?
There's variations is sizes amongst cars in the *same* class in just about every class you look at, and while you might see a significant difference at the top and bottom ends of that class it doesn't mean the largest car is in a totally different class. Is the Prius bigger than a Corolla? Sure it is, but it sure as shit ain't *that* much bigger that it jumps up a whole class size.
I've spent time in both a Prius and a Camry, and if you think those two vehicles are both in the same class with regard to size then you're kidding yourself.
