The best way is to charge to 100% then drive it to 0% and note the kWh used on the display.
I think the best way is to drive it to 0% and then charge it to 100% and note the kWhs that are reported as put into the pack.

So how about a bit of gratitude for things like this?
About to buy a used MS .. may I ask .. how, exactly do you get the pack capacity in kWh ?
thanks in anticipation - coming from roadster I have a lot to learn about MS
Thanks Buster, Mike and Jon. That is the sure way to measure KWh.I think the best way is to drive it to 0% and then charge it to 100% and note the kWhs that are reported as put into the pack.

Where in the car are you reading that number?

These methods give two different numbers that mean different things. The ratio of the two gives the charge/discharge efficiency of the battery, which is the energy extracted from the battery divided by the energy delivered to the battery. For my car, the ratio calculates to about 94% efficiency.I think the best way is to drive it to 0% and then charge it to 100% and note the kWhs that are reported as put into the pack.
I use a map to find roads. What does it mean to re-map an engine?
But those engineers don't manufacture cars. Another group is saying "hey it's cheaper to source, inventory and warranty the most expensive part rather than have four different parts". That is why Tesla didn't build a cheaper motor in the 75. They just used the 100 motor....Do you really think the engineers modern day sophisticated and highly complicated engines are so stupid to build in any extra power but not try to sell it?...
If you can, please read the article I've linked in German. You are wrong. Each performance level has different parts. At least with German manufacturers. They only keep replacement parts of the most expensive and thus best performance part but the initial build is very individual. The guy that writes there is an engineer and I know for a fact that what he says is implemented just the way he says. Imagine you build just 400 000 cars of a given model in 4 different perfomance levels. Buying top spec pistons will be more than double than the cheapest ones. So you would really spend 300 000 times too much in order to save stock which almost a non-issue with just in time production?But those engineers don't manufacture cars.

Thank you for this detailed explanation. As I read the above - I get the impression that "Chipping" and "Mapping" are the same thing. Did I get that right?A modern internal combustion engine uses a computer to control several areas of operation, most notably fuel injection quantities and timing and spark timing.
That computer generally uses a multidimensional lookup table based on throttle setting, rpm, measured intake air temperature and flow rate and a few other factors to determine the correct fuel amount (once warm it also adjusts based on the results of the exhaust oxygen sensor.)
Remapping an engine is changing that lookup table. You can typically get 5-10% more power from a naturally aspirated engine, and 30% or more increases from a turbo engine by changing the tables.
Of course, that means pushing the internal components harder, which can lead to more failures. For example, the vast majority of the high pressure fuel pump failures on the VW 2.0T happened on chipped cars - the pump was apparently just strong enough for the designed application, and when the chips turned up the fuel pressure to match the higher boost, a lot of them blew.
Most chips also increase the emissions produced. Between this and the regulatory testing requirements, they are usually marked as "off road use only" - and routinely illegally installed/used.
Most manufacturers deny warranty claims if they know a car was chipped - resulting in an endless competition between manufacturers and chipmakers to detect and hide the chipping.

Years ago I was aware of something called "blueprinting" an engine to extract a tad more power. Is "Chipping" and "Mapping" the same thing (modernized equivalent of) blueprinting?
