I've got a P85D that's coming up to 3 years old. I love the car but the real world touring range is slightly disappointing. Even with a full battery, a planned 340km journey (direct, no SC stops) out of Adelaide brings a warning to keep the speed below 100km/h. How much better is the P100D on range? I'm particularly interested to hear from those who have made the transition from P85D. Thanks in anticipation!
