I just looked at the link to the press release in the lower left corner. It's dated November 9, 2007. I don't pay too much attention to it because of it's weight, so I am not aware of it's abilities.
I am aware of the GM hybrid tranny, which is supposed to be maginificent. The electric motor is built into the tranny. Auto-stop and V8->V4 cylinder deactivation.
Google google google ... Here's the article on the tranny I was thinking of :
Three GM SUVs with Two-Mode Hybrid Engines | Green Car .com
Quote:
A Cadillac Escalade SUV that gets up to 20 mpg in city driving? General Motors says that its 2009 luxury SUV will deliver more than a 50 percent improvement in fuel economy in the city when equipped with the company’s new two-mode hybrid system. This is the same percentage increase as the 2008 GMC Yukon Hybrid and Green Car Journal’s 2008 Green Car of the Year, the Chevrolet Tahoe Hybrid, although one mpg less estimated city fuel economy than these latter two. While the Escalade’s fuel economy is not up there with a Prius, this is worlds better than the 12 mpg EPA city rating for a non-hybrid 2008 Escalade and represents an intelligent application of technology to improve environmental performance.
GM’s 2008 Chevrolet Tahoe and GMC Yukon Hybrids will be appearing in dealerships any time now, while the Escalade variant will be available next summer. Chevrolet Silverado and GMC Sierra two-mode hybrid pickups will also show up in 2008. The two-mode hybrid is the product of a joint development program between GM, DaimlerChrysler, and BMW that began in 2004. The technology is based on the very successful Allison hybrid transmission used in large buses now operating in many U.S. cities.
