El Camino Real was a man-made feature. The name is Spanish for the royal highway. It started in the 18th century as a foot path from Mexico City to San Francisco.
Now you’re really going to kick yourself:
Jeep Wrangler Sahara
One of the original names of Mt. Rainier among the local indigenous people was “Tahoma”. From that name came the city of Tacoma, and (I assume) the Toyota Tacoma.
And Jeep Gladiator Mojave.
Fairly sure the truck was named for the city. And there’s dozens of vehicles (most of them pickups and SUVs) named for cities. But the OP excludes those.
Addition: Subaru Baja
This topic overlaps somewhat with a thread I started on the old site:
Unfortunately, Discourse doesn’t support the lists from the old board, so my list looks really funky. Also, I somehow missed Toyota Sequoia on my list.
