the 280e in a car struggles to get low twenties on the highway with mid to low teens around town. the G wagen is heavier and much more boxy.

my 87 mitsubishi montero is very comparable body wise and probably weight too and with its little 2.6 liter four and an automatic gets mid teens highway and probably not much worse around town. it will just do 75 if pushed on the highway.

I imagine with half again the horsepower a 280G would do 85 or maybe 90 in a pinch but get the mileage described above.....probably not more than mid teens highway and then only if staying around 65. I bet if you go 75 you will get low teens.
