Auto Transfer of Power Front to Back

  • From all of us at Scout Motors, welcome to the Scout Community! We created this community to provide Scout vehicle owners, enthusiasts, and curiosity seekers with a place to engage in discussion, suggestions, stories, and connections. Supportive communities are sometimes hard to find, but we're determined to turn this into one.

    Additionally, Scout Motors wants to hear your feedback and speak directly to the rabid community of owners as unique as America. We'll use the Scout Community to deliver news and information on events and launch updates directly to the group. Although the start of production is anticipated in 2026, many new developments and milestones will occur in the interim. We plan to share them with you on this site and look for your feedback and suggestions.

    How will the Scout Community be run? Think of it this way: this place is your favorite local hangout. We want you to enjoy the atmosphere, talk to people who share similar interests, request and receive advice, and generally have an enjoyable time. The Scout Community should be a highlight of your day. We want you to tell stories, share photos, spread your knowledge, and tell us how Scout can deliver great products and experiences. Along the way, Scout Motors will share our journey to production with you.

    Scout is all about respect. We respect our heritage. We respect the land and outdoors. We respect each other. Every person should feel safe, included, and welcomed in the Scout Community. Being kind and courteous to the other forum members is non-negotiable. Friendly debates are welcomed and often produce great outcomes, but we don't want things to get too rowdy. Please take a moment to consider what you post, especially if you think it may insult others. We'll do our best to encourage friendly discourse and to keep the discussions flowing.

    So, welcome to the Scout Community! We encourage you to check back regularly as we plan to engage our members, share teasers, and participate in discussions. The world needs Scouts™. Let's get going.


    We are Scout Motors.

When the back tires have traction but the front tires want to spin, I would like for the system to transfer power to where it makes sense. Almost like Anti-Lock brakes, but more of an Anti-Spin Management System.

There are many times when I find myself in a situation (climbing an off-camber trail) where my back tires have plenty for grab (weight shifting back on a climb) but my front tires are struggling for traction. Sometimes, this can be in a spot where I'm more concerned about my front tires directing than I am about pulling. If they begin to spin, they can become worthless in terms of directing my path of travel. Even in a hard turn, if they spin, the front of the vehicle can "walk" in the wrong direction.

I think it would be great if the Anti-Spin Management System could sense tire spin and reduce power to that axle. This might need to be one of those cool toggle switches you're planning and it could be engaged only when needed.

The marketing would read, "The New Scout with 'Spin Guard'". We would have to talk with Bill, but maybe, "The New Scout - The Spin Stops Here!" *grin*

Most EVs can do traction control at about 500 to 1000 times per second compared with 10-15 Hz for most ABS systems.

Check out this video. It's related to 0-60 and quarter mile times, but the details about traction control for EVs are important not just for the speed off the line, but also for traction in low speed applications such as offroading. I hope Scout Motors will do a whole lot of testing and tweaking of their traction control so they can eliminate wheel spin in low speed, high-torque applications. The capability is there, it just requires a lot of detailed programming.


Warning, Hagerty Media is a rabbit hole of fantastic videos about fantastic cars and you may not resurface for some time....
