During my commute to work, I have been trying to improve my efficiency, but have never really been able to drop consumption below 300-315 Wh/mi. Maybe it's the hilly terrain around here, but I've always felt that there even was a measurable penalty driving carefully in Insane mode vs. Sport, and I always have Range mode enabled. Lately, however, I've noticed a remarkable improvement, as I can now get into the 290 Wh/mi range, even in Insane mode, with Range mode on. For the first time ever, I've been able to beat the rated range. I am on 2.5.85, my P85D has a staggered 21" setup and my lifetime average over 10,000 miles has been 370 Wh/mi since I got the car in December 2014. Have there been any recent improvements in torque sleep and has anyone else noticed any change? Maybe it's just the favorable temperatures?
