Please do the math for me, or provide stories of successes anf failures of climbing vehicles.

Thanks.

If 70k 18 wheelers can do it in the mountains why couldn’t a passenger van handle it? Where are you trying to drive?

In college and law school I taught rock climbing at a camp in NC, we took 12 kids (15-18 so pretty much adult sized) and 3 instructors plus several hundred pounds of climbing gear over some pretty steep mountain roads in a standard 15 passenger van. I would guess many of the grades were over 10% and quite a few over 20% for short stretches. After turning 21 I often drove and don't remember it being any real issue.

At 300 ft lbs of torque, assuming the avg passenger is 150 lbs and the van is full, a 15 passenger van can climb a maximum 67.4* rise at 58.9 mph.

You gotta really want it to be going 58 on a mountain.

ETA: backroads of mountains

Depends on how much the victim in the back of your van weighs.

Lot of variables to consider. Wheelbase, front bumper ground clearance, rear bumper ground clearance, surface material, stall speed, just to name a few.

Way to vague. If you get a 15 passenger with the Mercedes Diesel (SP-15), then you have shite-ton of torque (325 lb-ft @ 1,400 rpm) that will take you up any hill you need to climb.

As for incline...approach angle is 19 degrees and departure angle is 15 degrees...but that is unloaded.
