Real world range on the Lightning is still TBD (probably TBD on the Rivian, as well, though we'll find out soon). I'm not sure the 4 motors vs 2 really matters. The F150 is claiming 563hp/775 lb-ft. That's more than enough for anyone.
Everything I’m reading is you will have a choice on range with the Lightning meaning a 2nd battery can be purchased for extended range. From early reports it will take both batteries to meet the range of the Rivian. As you said time will tell. But my bet is the Lightning will cost way more than early reports for performance/options that compare to Rivian. Common sense tells me that having more drive motors equals better performance, towing and payload. We shall find out soon enough though. Exciting either way.
