Based on the definition of longitudinal vs. transverse, I would have to agree with you that V6X would be the proper code on the plate of the car that is the center of this discussion. Maybe someone didn't tell Newark that though and they got it wrong on the fender tag of this car at least. As much as I would like to read the code as a 6 in the middle, it sure does look like an 8 instead. Note that there is a "6" digit in the VIN for this car for sale on its body code plate, and it doesn't look like the number in the center of the V _ X code on the plate. And there is an E85 code on the plate of this car and the "8" in that position does look like the center digit of the stripe code as best I can tell.
