again-around 3 times the total torque at the tires in high gear with a 4.5ish rear gear 700+ lb.ft.v-8 engine at the wheels. 700x4.5=3150 lb.ft. Something to think about.
I know everyone thinks they put on a lot of miles in the dunes but don't really . I only put on about 200 odometer miles in 8 hours non stop driving last week. If I had been with our group it might have topped 300.

Once the wheels spin with an electric motor the amp draw will actually drop until traction is regained enough to require more power to keep spinning. With the weight of the batteries something like this will never be suitable in the dunes as much lighter machines are. That's a given.

That's a given.i shouldn't even meantion it in miles as there site does cause diff terrain will drain it faster or slower anyway. your right, once traction breaks there be less amp draw but still an amp draw eating power fasterand a gas engine will use more fuel. Ultimately it's a trade off especially since most sxs's have pretty dinky gas tanks and likely have no more run distance. The issue will come down to recharge time and getting the battery weight down. i agree these werent designed for the dunes and yes once the tech gets better and cheaper the real builds will start. until then 5300 lbs in a utv is just too much.
