I recently completed a 2,000 mile trip and logged a lot of data along the way. P90DL Sig X. The error I am seeing is repeatable. On a non-stop leg, here is the data: Actual miles: 139 Rated miles consumed: 155.9 (rated range at start of trip minus rated range at end of trip) The car is rated at 333 Wh/mi Rated miles consumed * Rated Wh/mi = 51.9 kWh Avg Energy Consumed (51.9 kWh / 139 actual miles): 374 Wh/mi I have attached the trip meter for this leg. It shows: Miles driven: 139 Total Energy: 48.7 kWh Avg Energy: 350 Wh/mi 48.7 kWh consumed to go 155.9 rated miles equates to a car rating of 313 Wh/mi. A car rating of 313 Wh/mi and a range of 250 miles would equal a battery of just 78.3 kWh. Thoughts? Is there a flaw in my calculations?
