Yes, it is!! Thanks to you and the LOC for the hints that I read prior to taking delivery of the RX. One off thread comment because I find it interesting. Because of where we drive, we have noticed some differences from what I have read about. Already, I have completely charged the traction battery several times (it happens on the loooong downhills here in the mountains). When you achieve complete charge the RX uses the traction battery and electric motor(s) instead of the gas motor at much higher speeds. I've pressed the accelerator and had it use the electric motors at over 50. On our trip to Breckenridge, CO we drove the eight to nine miles from Hoosier Pass to Breckenridge without using the gas engine at all, even though there were several periods where we were not coasting. :D
