Whatever Elio Motors considers it to be is what it is... They would know. I doubt they pulled P4, and all the other model #'s, out of their @55
it appears you've noticed that some of our newer members with an axe to grind consider themselves to experts on the inner workings of EM .... as such they believe they know more about everything Elio than the folks do who run the company ....
.... while in high school I found I enjoyed English Literature (kind of odd for a fellow who became a PE major in college
) .... when I read some of their rants in which they twist things to suit their purpose, I can't help but think back to one of my favorite quotes from the Bard in Macbeth (Act 5, Scene 5, lines 17-28)
"Life's but a walking shadow, a poor player
That struts and frets his hour upon the stage
And then is heard no more. It is a tale
Told by an id**t, full of sound and fury
Signifying nothing."
