Executives now admit, grudgingly, that endless fights over fuel economy have badly damaged the reputation of the Big Three, undermined their marketing efforts and helped Asian automakers make even deeper inroads into the U.S. market by attracting a new generation of young buyers to the brands.

The system operates from the Calor Gas, liquefied petroleum gas (LPG) or propane that is already on board for cooking. The system will fit comfortably in an aft locker, normally used for a conventional generator.

The Cadillac Provoq fuel cell concept uses GM's E-Flex propulsion system, combining the new fifth-generation fuel cell system and a lithium-ion battery to produce an electrically driven vehicle that uses no petroleum and has no emission other than water.

Powered by a 100 kW electric engine and fuel cell stack, the i-Blue is capable of running more than 370 miles per refueling and achieves a maximum speed of more than 100 miles per hour.
