The two-mode hybrid system will be coming soon.  The Allison Transmission division of BMW, GM, and DaimlerChrysler originally developed this system.  This alliance is called the Global Hybrid Corporation.

The reason that this system is called a two-mode hybrid is because it has high and low-speed modes for the electric variable transmission.  Four fixed gear ratios have been included for high efficiency.

Some of the same functions are featured that are on the Ford and Toyota one-mode hybrids.  For instance, the vehicle will turn off at a standstill, while breaking the batteries charge, and the electric motor, the engine, or both, can be used to power the vehicle.

The two-mode hybrid is very adaptable.  It can be used with several engine or drive train configurations.  In addition, it can be mated to engines powered by gas, E85 or diesel fuels.

This new system will be put into the GMC Yukon and the Chevrolet Tahoe by late in the year.  Mercedes and BMW will also be offering this system, but they haven’t stated what cars will be utilizing this technology.  With any new vehicle technology, an auto warranty is a necessity.  After all, you don’t want to pay unnecessary repair costs in the future.
