Where have you been? .179 has been discussed here for weeks... and yesterday someone claimed to have seen .180
I have .179 on my car and compared to the S60 on trips that I have done many times with the S60 my Wh/mile run about 20% higher than with the 60. So I have 30% more battery and 20% more consumption. Not exactly what I envisioned :-/
I was upgraded to Firmware 6.1 2.2.179 with a ranger last week. While he was installing he indicated that this update while mainly for the D models, WILL INCREASE RANGE, by providing better efficiency while coasting or at low cruising power levels, I would also notice a difference in my P+. Last night I did a drive to my Dad's house, which is a trip I do almost weekly. I normally use 310 to 320 Wh/mi. Following this upgrade, I used 272 Wh/mi. This is a HUGE increase in range!! This is only the first evidence I have.
Does anyone else have this version yet? Are you seeing the same increases??
I've had the pleasure of driving a brand-new P85D loaner all day today while my P85 is in for service. Done quite a lot of testing with it. It has 6.1 (2.2.179).
I did my usual 51-mile "economy test" route through, which includes some freeway driving & regular roads, traffic jams, a little bit of uphill & downhill, and generally very gentle acceleration that probably puzzles other motorists. One half of the trip I did with RANGE ON, the return half of the trip I did with RANGE OFF to see if it made any difference. In my P85 both halves of the trip are generally made using about 265-275Wh/mile. The P85D did it with 299Wh/mile on both halves of the trip (I was surprised that it was the same number on both directions but there you have it). I am not sure if this should be viewed as "economical" and I don't have any older P85D data to go on. Theoretically though, at some point the rear motor on this P85D
ought to have gone to sleep, allowing the car to use the front (smaller) motor and less energy than my P85. From the trip data, this never happened. P85D currently using about 10% more than the P85 while driving in the same manner. While gunning the P85D for fun, of course, it gets much worse although my average for the entire day has been 343Wh/mile which is still 99MPG!!!
