I have a MYLR on order and my dad is considering ordering one as well. He carries a lot of gear around for work (about 400lbs) and wants to know how the range is affected with that amount of weight in the back of the car. I'm assuming there is some loss, but haven't been able to find a good estimate. Anyone know? Thanks!

Range Loss with Cargo Weight?

Look at ABetterRoutePlanner. In the advanced settings you can adjust the additional weight. See how it affects some drives that you plan.
In a conventional vehicle weight/extra weight has a greater impact on efficiency. You have to burn gas (or diesel) to accelerate from a stop to the cruising speed. When you come to a stop all of the energy in the vehicles momentum is lost as you slow down and brake. The next time you start moving you have to use more fuel to get back up to speed. In an EV with regenerative braking when you slow down or stop approximately 70% of the energy is captured and put back into the battery. You can use that energy to extend your driving range.

Q: How efficient is regenerative braking?
A: Efficiency of the regenerative braking process varies across many vehicles, motors, batteries and controllers, but is often somewhere in the neighborhood of 60-70% efficient. ... This simply means that 70% of the kinetic energy lost during the act of braking can be turned back into acceleration later.

The article says drivers report regaining 32% of total energy use, so extending a 100 mile range to 132. But if you drive 100 miles and never hit the brakes, you extend the 100 mile range 0 miles through regen. You regen a higher percentage of total use when doing a lot of stop and go.
The 70% figure is referring to the percentage of braking power that is recovered. Both can be true.
The first is about how much braking drivers do in a typical drive. The second is about the efficiency of converting the kinetic energy back into stored potential energy in the battery. 70% seems to be in the ballpark given other estimates on charging efficiency.
