No, GM had always stated that the Two Mode was going into the Trucks/SUVS as that is where they could gain the most with the first generation, as can be seen by a Hybrid Tahoe getting better city milage than a Camry, you do the math on the weight difference.
Actually, if you were informed you would know that the two mode system was on city buses before it even got to the trucks/suvs. GM started by trying to make the most inefficent vehicles more efficent, than taking the easy way and making a small light car more efficent.
Also of note, there was never any official statement of the exact cost of putting the Two Mode into a vehicle but the closest we got that I saw was Bob Lutz indicating it would cost about the same as a small car, so roughly $10k. Which means that putting the system into vehicles other than high end full size SUVs did not make too much financial sense, as unless GM wanted to give up $5-8k per vehicle in subsidies to make the system a $2-5k premium over another model the demand would not be there in gen one vehicles as the excess cost would take too long too recover in gas savings over the life of the vehicles, If you could recover that kind of money over 3-5 years when say you have a Malibu already getting pretty good mileage, the returns diminish the more efficent the vehicle already is.
You will of course note that Toyota is inuable to use the Hybrid Synergy Drive on anything larger than a Highlander as the the weight of the vehicles makes their system useless. Or as you would put it...
"Toyota was too stupid to impliment their hybrid system on a medium SUV".
Then again Toyota was poo pooing the Chevrolet Volt because the battery system wouldnt work etc, when in fact Toyota had a heavy financial (production plant) interest in the batteries it uses for the HSD, so it had no interest in seeing the Volt working as it would make the HSD setup irrelevent. Then, once the Volt actually started progressing and GM was actively testing muels and getting the expected range Toyota suddenly changed its tune and cried ME TOO!!!!!! and decided to preannounce (vapourware) a Prius or similar with a similar setup to the Volt. Oh me oh my!
Hybrid wise GM was slow to the party, then once it arrived and had the product it wasn't financially in a position to get the technology into all the vehicles. Toyota tooks years to get the Prius into a position where a vehicle sold with a profit, yet even then it might take a while longer to call it truely profitable since so few people want to buy one now that gas prices dropped.
Oh I know the Two mode was in their buses. And I am not criticizing GM for putting the Two Mode in the SUV's first. I am saying they were stupid to engineer the Two Mode to only fit in the SUV's/trucks. BAS sucks and that much you should be able to admit. The Malibu hybrid only gets 1 MPG improvement over the regular one with the 4 banger/6 speed combo. I hope BAS+ is a major improvement that can make it rival the Camry and Fusion hybrid.
I am on GM's side. I have an Aura XR and I love it and I am eyeing a Camaro SS in the future. But, I can not excuse GM on their mistakes.
