while you are on point about a lot of things, GMs hybrids have been lambasted by the press. the silverado was described as an expensive power outlet. the vue hybrid is using the same system (large bet driven alternator type thing) and doesnt get teh same fuel economy as a ford escape or toyota ighlander hybrid for that matter.
at this moment, toyota has a massive headstart on everyone. except possibly honda. but honda arent trying to get all out milage it seems.
and toyota sold over 100000 priuses last year. thats one hundred thousand. i thought it was a fringe car. i guess it aint.
but thats volume some manufacturers wish they had in a single car; mitsibishi, isuzu, lincoln (trucks aside) mercury, saab, etc etc etc
...True, the VUE Green Line is using the BAS system similar to the Hybrid "joke" that was in the GMT800 Silverado, but there is also the new Two-Mode system as well as the ECVT transmission that will be adding to the hybrid-lineup at GM starting later this year.
The AHS2 system ("two-mode" at GM) is the system that was co-developed between GM, Daimler-Chrysler and BMW. The setup that will be used is similar to that of Toyota's "Hybrid Synergy Drive" and Honda's "Integrated Motor Assist" in that it will combine the power of the electric motor with the gas engine to propel the vehicle.
But, that is where the differences end. In "Input-Split Mode," the new setup would allow the two electic motors to propell the vehicle through the first two gears of the 4-speed automatic. Of course, this only occurs at low speeds, and will vary the ammount of power needed between full-electric, gas-electric, and only gas, thus making it a full-hybrid similar to the Prius and Insight, etc.
In "Compound-split mode," the gasoline engine is always in use, but with tools like "Active Fuel Management" it allows the engine to consume less fuel throughtout the four-gear range. In this mode, a combination of electic and gasoline sources can be used to move the vehicle, but not in low-speed settings.
All of this happens because of the new transmission, which acts essentially as a CVT, despite the fact that it is an automatic... Hence the ECVT name. Being that the ECVT is only about as large as the regular 4L60E which is seen in almost every GM product, in theory, nearly every GM model could eventually offer a Hybrid setup as an option, the only problem for engineers becoming where they would put the new electic batteries.
...As of right now, the system will first be seen on the Tahoe/Yukon/Escalade Hybrids twards the end of 2006 into 2007, and the system will also be featured on the 2007 Dodge Durango Hybrid as well.
There have been plans to use the steup on the Opel Astra diesel, but no offical announcement has been made by GM.
