That's true, +.

The last 3 miles of my commute home I can get 99% ev-only, but that's after spending 30+ miles on the freeway and the ICE is definitely sufficiently warmed up, and the batteries have a high charge. I use the EV switch and up goes the MPG. With a commute of 3 miles only, most, if not all of it, will be spent warming the engine up.

But like + said, I wouldn't expect much less than 40 to 50mpg anyway depending on your Speed Racer tendencies!
