The WLTP range tests do not take account of heating and cooling ... if they did it would have to be quoted as a range at a particular temperature. IMO the improved range is therefore unlikely to be related to any efficiencies gained by the heat pump.
WLTP protocol has a defined temperature for the test. For Europe I think it’s 14C. The M3 shares/moves heat between systems (cabin, motor, battery etc) using coolant and I think the car isn’t charged immediately prior to the test- so quite possible heat pump will impact on the result.
There’s also a rumour of increased battery density.
Which is my own bet for the primary reason for the range increase. There may well be a temperature standard for the environment but the HVAC won't be used to maintain a specific higher or lower temperature in the cabin ... but as you say it will play some role in the general management of temperature of the battery so there may be an effect. It would be interesting to get information from Tesla occasionally on these kind of things!
Thats pretty much the consensus from what I read anyway. Until we have a WLTP standards expert available that’s a reasonable supposition. And only Tesla knows if there is benefit to range through temperature management of battery and motor... and they don’t tell us!
Model S and X have had a bump in range recently as well and as far as I know nothing has changed with them in terms of heat pump etc, so logically it would have to be something else, and something that is not unique to one model. The smart money would therefore be on something like battery density, as said above.
The parts catalog and videos previously shown suggest that the console goes over the top of the induction mat, and there's no indication at all that there are holes or whatever for cables to go through (see 4 and 13 in the image below)
Had a ranger come out today to reinstall my door handle, and he seemed to think that Tesla would be offering a retrofit for the powered boot. Obviously hard to gauge how accurate that info is, but would be interesting. He said that it was one of the most common complaints he'd heard from new and other Tesla model customers.
Looks like there are 2 USB C sockets in the cubby hole under the sliding door.

Suspect you'll need to run a cable from there if no wireless charging which is a bit crap as you'll run a cable up and out of the cubby hole, across the length of the sliding door to your phone that's resting in the wireless charger.
Well we now know where the range increase comes from!
