Rivian has a heat pump as do all of these cars. They just don't use it in reverse to draw heat from the air as Tesla (and some others do) but look at the trouble Tesla has been having recently.I'm really curious to see what below freezing temperature does to range as Rivian has chosen not to add a heat pump...
How have you concluded that Rivian's preconditioning is inadequate or missing?...or proper cold weather preconditioning.
EPA range numbers are useul for rough comparisons of vehicles because they take out the variability, to the extent that is possible, in realized range on the road but what is really of interest is consumption data (Wh/mi). It is that which you use during a trip to determine your "fuel condition" at any given point and on which you base your determination as to whether you will reach your destination without a supplemental charge. What we want to see reported by people who are actually operating the trucks is the Wh/mi they see in town, the Wh/mi they see on the highway, how many wH/mi are added when the temperature drops below freezing, how much rain adds and, of particular interest to these trucks, how many Wh/mi are added when going off road into, for example, sand.Hopefully we can get some more specific range tests, the only accurate ones being from 100% to 5% at a relatively steady speed, no major altitude changes, and temperatures listed. Lots of people improperly math out range.
What we really hope for is that folks like the people that did TeslaFi and Stats will release similar apps for the Rivians. That would depend, of course, on the existence of an API. Is there one?[/QUOTE]Photos of the trip computer showing efficiency and mileage is ideal. Unfortunately it's like 0-60 times and people often exaggerate.
