Unlike you, I own a Volt, so, unlike you, I don't need to lie about the numbers.
It gets 25 (winter) to 46 (mild weather) miles per charge for me. When the battery runs low and the gas engine is powering the car, it delivers 38-40 MPG depending on speed. My lifetime economy (4.75 months, 4350 miles) is 255 MPG. I'd say that's pretty good, considering my Lexus was getting 19 MPG on the same commute.
Apparently you're also not smart enough to do the math, it turns out the Volt is cheaper than the average car.
$45.5k sticker (loaded)
$7.5k tax credit (complain about this and I'll complain about the child deductions I'm funding with my six figure income)
$11k gas savings (5 years, for me)
= $27k gas vehicle equivalent (the average new car sale price in the US is ~$29k )
If you're still not convinced the Volt is a good idea, I suggest you start reading this blog http://physics.ucsd.edu/do-the-math/
