The Model X (photo via Ron Talain)
A Tesla Model X was just spotted on Monday (May 4th) by Ron Talain on Rt101 (near "the University exit") in California only a few miles from the Tesla Home Planet in Palo Alto. Ron described it as looking "... like a Model S with a pug nose."
New changes (visible) appear to be the rear bumper assembly and a more refined back window.
