December 16, 2004 DaimlerChrysler and General Motors have announced a cooperative effort to advance the state of hybrid technology. The companies plan to work together to develop a two-mode full hybrid propulsion architecture for applications in GM, Chrysler and Mercedes Car Group vehicles. The full hybrid with two driving modes optimises power and torque for the given driving conditions. The first mode provides tremendous fuel-saving capability in the low-speed and stop-start driving conditions typical of urban commuting, with a combination of full electric propulsion and supplemental combustion engine power. The second mode is used at highway speeds to optimise fuel mileage, while providing full engine power when conditions demand it, such as trailer towing or climbing steep grades. All the driver feels is the satisfaction of low fuel consumption and an ample reserve of power and performance.
