"GM calls the system a two-mode hybrid because it improves fuel economy both in city and highway driving. Other hybrid systems reduce fuel consumption in city driving, but have no effect at highway speeds.
The rear-drive hybrid Tahoe rated 21 m.p.g. in the city and 22 m.p.g. on the highway in EPA fuel economy tests. That compares with 14 m.p.g. city and 20 m.p.g. highway for a similar gasoline-only Tahoe."

Wrong. The Prius is fully ulitizing electricity all the time to further efficiency, even on highways. Duh.

And 22 MPG is certanly better than 20 MPG (highway), but at the expense of higher overall emissions? See the attched .pdf.

THAT is simply stupid.

And 50 grand for a marginally more efficient vehicle that is dirtier? who are these suckers who will buy this? How does this get into the hands of many, to really make a difference? A limited market with limited availability? Wow, and I thought it couldn't get any worse.

I'm sorry, but GM is laying yet another crap-brick. I'm just not a big fan and need to rant. YMMV.
