A few things...I can't even begin to understand the fascination with hybrids
You're paying more to save some gas, where unless you own it for years and tons of miles, won't recoup the difference.
What am I missing?
One: if you're in stop and go traffic alot, it's nice to be in all electric mode to save the cost on idling your car.
Two: If your commute is short enough, you could theoretically go to work and back on electric alone...saving on gas or time lost fueling up.
Three: As others have mentioned, you can have the 100% electric torque available when you need it. It's sort of like a bottle of nitro.
It's got it's appeals, especially as we bridge the gap between ICE and Electric. You get to enjoy the benefits of an electric vehicle for a short window and then go back to having an ICE vehicle...less of a compromise for many people.
