Advanced Hybrid System 2

Advanced Hybrid System 2 is a set of hybrid car technologies jointly developed by General Motors and DaimlerChrysler. It uses two sets of gears in an automatic transmission: One for the internal combustion engine and another to multiply the power of a pair of electric motors.

The system was first used in the General Motors transit busses deployed in 2004. When GM and DaimlerChrysler engineers realized how similar their hybrid work was, they decided to join forces and share technology. This parallels the work of Ford Motor Company and Toyota, who also independently developed similar hybrid systems and shared patents.

The following vehicles will use the Advanced Hybrid System 2:

• 2007 Chevrolet Tahoe
• 2007 GMC Yukon
• 2007 Dodge Durango
