Took my 04 G500 on its first extended road trip. Seattle to Santa Barbara via the coastal highways 101 and CA-1 utilizing public dispersed camping land for overnight stays. Averaged 14mpg and 35mph over 2,950 miles, guessing about ~35% of that was off pavement. Best mpg was 16 in moderate traffic feathering the throttle and using only the massive gravitational pull of the vehicle to slow itself.. a lot like driving an EV with brake regen
Spent the first night in the Tillamook State Forest with some heavy rains.. nice and spooky.
