> I've made a sport (a demented sport admittedly) out of asking folks with them what "Rubicon" means. I've not yet found a correct answer.

Did any of the "incorrect" answers include "it's named after an off-roading trail"? Because it's named after an off-roading trail used by Jeep as a testing/proving ground[0].

Most of their trail rated / trailhawk models contain some sort of nod to off roading trails. E.g., their "Renegade" contains maps of popular trails embossed into various bits of plastic.[1]

Never got that answer either. It's kinda interesting. and thanks for explaining that more modern use, as i'd not seen it myself, despite having had a Jeep and living not far from there for years, but not being an off roading sort in a vehicle other than a mountain bike.

Rubicon is also a reference to the Rubicon trial, a popular 4x4 trial running from Sacramento to Lake Tahoe. The trial was named in 1840, and may itself be a reference to caesar's crossing.

very cool...had not known that modern trail, and lived not far from it for years. thank you

on a jeep it refers to the fact that the particular trim level is able to successfully navigate the famous rubicon trail - a offroading trail. no wonder people are confused by your question

thanks for citing it: i hadn't known of it, and we had a 2014 Jeep Cherokee and had driven from Tahoe to the Bay Area before, ignorant of the more current use of the name!

Pretty sure the Jeeps are named after the Rubicon Trail in California. Why it's called that, I have no idea.

Thanks for citing that, as we had a modern Jeep Cherokee and didn't know that trail, despite having driven right by there before.
