2022 Gen1 R1T. Winter range/efficiency. How do I fix it?

You'll have to forgive those who are giving you cheeky replies. What you're asking to do is basically get around the laws of physics. There is no free lunch.

Going from cold to warm takes energy.

Your heat bill goes up at your home, even your ICE vehicle will have efficiency hits as it burns extra fuel to heat up the motor just as your EV will use extra KWH to heat up the battery. If you keep the vehicle warm in a garage you're using your home's heat instead of having the truck make its own. (if your garage is heated you're just transferring cost, if it isn't heated then you're taking advantage of your home's inefficient insulation) Or, if you're preconditioning you are just changing the point of time when you are pulling KWs for heat.

Remember that the biggest waste in ICE vehicles is heat, and that heat becomes a free benefit in the winter - and an extra problem in the summer.

Just thought I would point out that the comparison over the last three winters might be a tough to do as well. Last winter was the third warmest winter on record in the mid-atlantic and New England area.

You could always have Rivian check the cooling system to make sure it is functioning correctly.
