Hummer seems out of style these days and I would not be surprised if the F350 went PHEV one of these years.
There was a prototype Silverado Hybrid, and it got good reviews. I don't think they ever produced it (or maybe did for one year?) but it did show that the technology is available. It doubled as a worksite power station!
EDIT: They still make it!
There were two different hybrids of these. At first, there was the mild hybrid version (http://www.nytimes.com/2004/11/07/automobiles/07AUTO.html?_r=0" onclick="window.open(this.href);return false; (likely a BAS solution). Then came the current two-modes (http://www.gmfleet.com/chevrolet/silverado-1500-hybrid-truck.html" onclick="window.open(this.href);return false
. They hardly sell at all (see http://www.hybridcars.com/october-2013-dashboard/" onclick="window.open(this.href);return false; and http://www.hybridcars.com/december-2012-dashboard" onclick="window.open(this.href);return false
. I don't think their BAS mild-hybrid trucks sold any better.
When GM first had BAS mild hybrids cars and SUVs (e.g. Malibu Hybrid, Saturn Vue "Green Line", Saturn Aura Hybrid), they hardly sold and were notoriously unreliable. GM killed those, later came out w/two-modes trucks and SUVs (http://en.wikipedia.org/wiki/Global_Hybrid_Cooperation#RWD.2F4WD_truck.2Fsuv" onclick="window.open(this.href);return false
but those are virtually dead too and all other the partners involved (Chrysler, BMW and Mercedes) abandoned two-mode long ago. Chrysler built probably the fewest the out of all of them, before bailing out.
GM has resurrected BAS mild hyrbrids w/their 2nd gen that they refer to as eAssist. At least those are selling better than the Gen 1 mild hybrids.
edit: Found more URLs on the mild and two-mode trucks. Also, some info about the two-mode SUVs.
