Saunders,
I was also stunned at a hybrid Escalade, hence, the reason for my post. Not to mention, the hybrid Escalade will be a limited production model so not only is GM using their hybrid technology for a small fraction of their customers they also are using the technology on a limited number of cars.
And...to top things off GM execs came up with the brilliant idea of marketing their new Escalade hybrid in China!!!! Sure, China is an untapped market (one of the last in the world) but marketing big, fat vehicles to an Asian market is a sure-sign GM is desperate. Why in the world would they choose the Escalade as the model to market to China? Read more about this here...
