I've had mine almost two weeks now, about 800 miles so far. I don't have specific numbers, but some general observations.
Averaged 42mpg yesterday over 30 miles of nearly flat highway with the cruise control set at 65.
City is a different matter. All the major streets here have 45 mph speed limits, and lights about every half mile. If I work at it, I'll get high 30's. That's with relatively gentle acceleration up to 40-43, then lift and hope I get enough EV to sustain my speed for a bit, the coast when possible up to red lights. But it's not magic, I've got to keep my eye on the EV gauge. If I drive it without regard for the EV gauge, I get closer to 30.
I'm in Phoenix, so the AC has been on all the time so far, and on days like today (113 degrees), especially if the car's been parked in the sun, it's cranked to the max. I'm hoping the non-AC numbers this winter will be a bit higher.
