How come the "Cyberbeast" model has the same 11k lbs Towing Capacity as the "All Wheel Drive" version ($30k cheaper)? The Cyberbeast has significantly more Torque at 10,296 lb-ft vs. "All Wheel Drive" at 7,435
- Toutouxc 3y agoTowing capacity is not a function of torque alone. You need to be able to brake your load, keep it stable behind the car and have enough juice on board to actually get it somewhere.
- ajross 3y agoPresumably the limit is the hitch, not the drive train. You can put only so much force on a standard-sized chunk of steel.
- xeromal 3y agoYeah, you'd need a goosneck at some point
- shrubble 3y agoIt could be a rating on the frame and hitch that keeps it at that level. Or possibly braking.
- mholm 3y agoLikely what the frame/towhook attachment is rated for, rather than the motors
- hotpotamus 3y agoWithout knowing much about towing things, I'd guess it's limited by the brakes. Could also be whatever attaches the tow hitch to the frame.
- xeromal 3y agoProbably limitation of the battery pack structure.
- stbenjam 3y ago11kish is usually ther upper limit of most half ton pickups. Probably a function of what the frame can handle. But Towing 11k on that thing is already going to tank your range to ~100 miles. I couldn’t imagine towing our camper with this thing (and the design is stupid enough that you probably can’t tow a fifth wheel right the cybertruck anyway)
- Aurornis 3y agoTowing capacity is generally limited by things like the frame, braking capacity, and cooling capacity. If you hook any automatic transmission truck up to a really heavy trailer (100,000 pounds) you can probably move it around, but if you try to actually tow it anywhere the truck will either overheat or crash into something when you can't stop it going down a hill. Torque really only determines how fast you can accelerate the load, not how much you can tow on the road. Also, EV "torque" specs are not comparable to traditional car torque specs because they're measured differently (ICE measured at the engine before the transmission multiplies torque to the wheels, EV measured directly at the wheels)
- sonicanatidae 3y agoAlso, traction.
- bo1024 3y agoAnd wheelbase / swaying, right?
- llm_nerd 3y agoI apologize for adding to a load of already good answers, but towing capacity is often limited by tongue weight limits (how much weight is sitting on the tow hitch, and thus supported by the suspension), which should be 10-15% of the total payload. While it seems like they could just balance the trailer and reduce tongue weight, if it is below 10% the payload becomes extremely dynamically unmanageable. The other limits come into play too -- torque, brakes, etc -- but tongue weight on suspension is often why there is a mismatch like this.
- saalweachter 3y agoWhich is also why to tow really big trailers, you need a gooseneck / fifth wheel hitch.
- esaym 3y agoTowing is complicated. Here is an F-350 at full throttle in second gear barely making it through mountains: https://www.youtube.com/watch?v=hoHDQ4SKpBI https://www.youtube.com/watch?v=hoHDQ4SKpBI
- FireBeyond 3y agoThat's an idiot kid who thinks that flooring it while towing several tons up a 12% grade is even safe, let alone wise.
- esaym 3y agoYes that is the point.
