We Own a Rivian R1S Compass Yellow. Lucky for us...Rivian discontinued the CY due to low demand. We own the R1S for 3 years and have not come across a single CY Rivian so clearly not many picked the CY when it was available.
My 34kW house generator has a clock that counts the number of running hours. It makes sense the Scout Ice engine will have something similar so the service is based on usage rather than time intervals.
Yes... however it is a good estimate number for calculating the battery size. The A/C load on hot humid days in South Florida eats up battery especially pre-cooling the car when parked under the noon Sun.
I have Owned Rivians the last 3 plus years and have driven 40k plus miles . The average is around 2.2 Miles/kWh. These numbers are based mostly on Highway driving in South Florida. I think a better approximation for the Scout battery size should be miles/2.2.
