We are converting a '72 M710 to all electric drive. We plan to use a twin AC brushless motor system that is manufactured here in the US. The battery will be taken from a salvaged Tesla.
Our first off road build was in 2013 when we entered the Mexican 1000 in an all electric off road class 10 car. Here's a photo of that build at the race: https://www.instagram.com/p/cnGGApgXCO/
What really drove us to this project was the capability of the Pinzgauer off road, and to know how much improved the vehicle will be with regards to trails, steep grades, rock crawling, etc.. Our peak torque will be available at 0 RPM, and will be approximately 260 ft/lbs, more than double of the gas engine. When we watch videos of Pinzgauers climbing obstacles, it seems like their only hinderance is a lack of torque, requiring the driver to slip the clutch so much you can practically smell it through the internet.
We'll be keeping it stock (to begin with) from the transmission back. We've had a lot of good luck with ZF transmissions over the years, so we'll give this guy a shot. We'll also be converting to 12 Volt, and a more 'civilian' electrical system. Sure stealth mode is great, but unnecessarily complicates things, as well as the 24 Volt system. We'll be able to keep the 12 Volt system well topped off by charging it from the main EV battery.
We do have a ton of parts from the vehicle that are available, so if you're looking for a used part from the 24 volt system, let us know. The gas engine is also available, as well as the dog house, and center cover since we'll be eliminating the engine cover and positioning a 3rd passenger seat up front.
Here's some pictures of the 710, and we didn't waste any time getting started. Engine and trans are already out, and we're getting ready to take the body off for paint. Thank you Vince and Real 4x4's for offering this place for us to share our build.
