We drove to Geneva and back last week, after V7 had installed. I haven't noticed any change in power consumption c.q. range, but I have serious problem with the climate control. With V6 I rarely changed the temp from a setpoint of 20C and never touched the settings.
With V7 I had to mess around with the controls for ages before the car got warm. The girls were wrapped in blankets, complaining about the cold. Eventually I had to crank up the setpoint cabin temperature to 27C before it was remotely warm in the cabin.
Further, in automatic mode, the climate control would suddenly dump cold air into the car, requiring manual intervention before we all got chilled again.
I checked with Tesla today it they confirmed that it is a known software problem in V7 and they're working on an update. Advice is to leave the heat turned up.
The other problem that I noticed is that the power consumption graph display gets screwed up. After a while data that has scrolled off the left edge, gets redrawn for a few seconds, then disappears, then is redrawn, etc. The range and average figures also hop around at the same time. Not too serious but at the end I was concerned about the accuracy of the range remaining calc, as the intention was to arrive home with 15km range.
Finally, the nav screen locked up and crashed/rebooted twice during the trip. All in all this seems like a qualitatively poor release. The few 'improvements', if you care to view them that way, seem to be outweighed by the poor quality of the update. I'd rather stick with software that's stable and works than get a superfluous UI update.
The Nav still completely sucks for long distance driving. The route it plans between superchargers is often laughably stupid. Eg, my brother (our destination) lives 20km north of Geneva. The nav planned to take us past his house to the supercharger south east of Geneva, before driving back to finish the trip. Stopping at Lully would have been far more efficient, but even that wasn't necessary. Egerkingen to my brothers place is just 198km.
Please Tesla, forget the UI and just give us a half decent navigation system.
