Interesting video regarding vehicle range extenders

  • 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.

Discussion on hybrid vs range extender. But he also talks about law restrictions with respect to range extenders. He didn't say if those laws have changed over time, but essentially in the US, the vehicle has to be able to go further on electric power than it can when the range extender is engaged. Don't know if that has changed over time, but he talks about how this legislation impacted the BMW I3

He's poorly informed.

It was an entirely voluntary action by BMW.

BMW was just chasing extra CARB ZEV credits in California. If your EREV had more EV range than gas range, and the Range extender didn't start until after you used something like 90% of the battery then you would qualify as a "BEVx" and gain extra CARB credits.

Also i3 was not the only EREV. The Fisker Karma was also an EREV, and didn't have any of these limitations because it was not chasing those extra credits.

Regulations here:

Search for "bevx". You can see comments from BMW on BEVx rules. I don't know how much hand BMW had it encouraging these regulations.

We can safely assume that Scout Motors will NOT chase BEVx status and impose these limitations.

I thought that was a good explanation, thanks!

Interesting, thanks for the added info!
