Thanks everyone. My car does do EV at higher mph's, but when the main battery is depleted and in hybrid mode only I cannot get the EV to power the vehicle above 60ish, especially with cruise, ACC on. My former car, Kia Optima Hybrid would go EV at highway speeds every 5-7 minutes for about 30 seconds and the ICE would shut off, I have not experienced that at all in my Energi.
