Hybrids and Hydrogen Rule
T face=Times>Detroit—As they have for several years, hybrids and hydrogen dominated the technical discussion at the 2005 Detroit auto show, but still more in terms of future promise than immediate product.
The biggest news on the hybrid front actually broke before Christmas, with the announcement that DaimlerChrysler and General Motors are joining forces to collaborate on development of the Two-Mode Hybrid system for use in both companies' products.
The starting point for the co-development program is technology initially developed for GM's hybrid transit buses, more than 200 of which are already on the road.
Heart of the full-hybrid system is an electrically variable transmission with two relatively small electric motors, each connected to a planetary gearset and housed within the space envelope of a conventional transmission.
