I believe you mean 466. Those numbers... are kinda weird, and are also talking about top speed, not range.

For what it is worth...

I took the rules from GURPS VEHICLES, GURPS WORLD WAR II, and the expansion (GURPS VEHICLE BUILDER software had it baked in) - all in an effort to GURPSIFY some of the Vehicles from CYBERPUNK 2077. I used the Biofuel option for determining range of vehicle and all that fun stuff.

I was content with the end results, largely because it brought down the excessively HIGH speeds (determined by Horsepower of engine) down to more "real world" realistic (in my opinion).

I treated the CHOO2 as biofuel alternative.

At some point in time, I probably SHOULD compare/contrast the vehicles designed that way (GVB) - and a translation to 4e format via the pyramid article I picked up (but haven't really utilized). Seems like in theory, it SHOULD work - but I've yet to try it.

The Basic Set does address this topic, in a way. If you consult the Increased Consumption disadvantage, on p. B139, it says that each level of the disadvantage doubles the food or fuel consumption, or halves the endurance. One level gives an endurance of four hours. So a typical vehicle, without Increased Consumption, has fuel capacity for eight hours. (You can also apply levels of Reduced Consumption, p. B80, to get tankage for half a day, a full day, seven days, or thirty days. Or, beyond that, Doesn't Eat or Drink, p. B50.)

If you just want to do gamable approximation, you can set some volume, weight, and cost of fuel for an SM 0 vehicle, such as a TL7 heavy bike (which might be given Increased Consumption 1), and then adjust that for levels of increased or reduced consumption, for increased SM, and for requirements for higher grades of fuel.

They work out okay, though they're not the exact numbers I'd have used. But they do deal with range, because endurance is fixed, so the slower a vehicle goes, the less range it has.
