Announcing our new "CLUBS" section where you can join or create a Rivian club or group! You can use this new feature to conveniently plan and discuss local events, gatherings or other club/group related topics.
So we encourage you to join (or start) special-interest and regional-based Rivian clubs at: https://www.rivianforums.com/forum/group-categories/clubs-groups.1/
1) The tank turn video is 100% CGI. No question. The feature, however is 100% real (have seen video direct from Rivian employee's personal cell) but will be off-road only.1) I don't think the tank turn was CGI, and am guessing the forward move first was to create momentum to help the truck break traction when executing the turn.
2) Ford train video is definitely hype, but probably effective marketing for most audiences. I'm betting a modern diesel truck could do the same thing...trains have low rolling resistance.
Not mine (from Republic Locomotive):Hmmm. The train weighs four times what the shuttle did. To me it's less a question of the torque of the towing vehicle than whether the friction between the tires and the ground surface would be sufficient to overcome the inertia of 1.2 million pounds, despite low rolling resistance once the load is underway. For instance, without antilock systems, hard braking almost any car will break the tires loose from the pavement. Would a typical small truck tire that would lose traction under heavy braking have enough friction to overcome the inertia of a 600-ton train? I don't have the math knowledge to calculate how much load is put on the tires by a rapidly decelerating truck of roughly 6,000 pounds, so it's an honest question, not an argumentative one.
