Here's my 500-mile tank. I had to take a gratuitous run locally to get over the 500-mile mark because I didn't want to run out of gas driving over CA-17 to Santa Clara. When I filled up, the car took 12.488 gallons (no topping off), which worked out at 40.7 mpg, vs 11.53 galls and 44.0 mpg shown by the car. Of course, my mileage might be better if I didn't drive back and forth between Santa Cruz and Santa Clara so much. It's frustrating to arrive at the summit with the battery 2/3 full, and then to run out of regenerative braking less than half-way down the other side. You'd think that, having a GPS on board, the PCM could take account of the upcoming downslope and stop the battery charging before the summit so that I'd arrive at the summit with an almost empty battery. Forcing the car to recognise the summit as an EV+ location didn't help, the upslope is too steep for EV operation. Any suggestions? --Ian
