The word "Ecotec" is nothing more then a brand name. It has no inference to the way the engine operates the way "Vtec" does on a Honda.
There are no less then 7 different Ecotec model engines. Two of them have variable valve timing, but that really has nothing to do with the name.

It usually has two different setting one for lower revs and one for high revs. The lower revs usually has more valve overlap, meaning the exhaust valve is open while the intake valve is for a short time. This helps create a suction of fresh air/gas into the cylinder and helps ensure all the burnt gas and air gone. At higher revs there is little to know overlap to ensure fresh air/gas is not escaping the cylinder before it is combusted, thus waisting gas.

^ good catch, but being that the source is wikipedia, which can be modified by the general public, it could have also read "the LSJ will continue on alongside the LNF as an alternative means of forced induction for the well received Chevrolet Cobalt."
Even though its almost certainly true that the LSJ is done, wikipedia cant be counted on for official information like that.

Partly it's a sales ploy -- make a base car and include a model with more performance to get the name noticed. Base model continues to outsell performance version by 10 to 1 (or more), model name is recognized, warranty work on the performance versions is high (in comparison to base models) -- solution: kill performance model and continue to sell base model cars.
Remember, the car makers are there to make cars AND make money -- if a model doesn't make the company money why should they keep making it? "Stupid" does not describe this normal business practice
-- it's business sense
Thread subject: If memory serves me right Ecotec has to do with ecology too, not only fuel economy but also the way the oil filter is made -- to reduce the amount of metal oil filter canisters in landfills

well.. first off... we can not use wikipedia as a viable source since it can be altered by the public... with that said.. who knows.. maybe this is the end of the cobalt ss.... or perhaps the beginning of the fabled and ill-rumored TURBO cobalt... LOL... THERE WILL NEVER BE A TURBO COBALT IN PRODUCTION...LOL... j/k j/k who knows
doesnt matter we will know the answer soon because June is just around the corner and it wont be long before we start seeing the '08 models... then we will know for sure
anyways... everyone get back to the original topic of this thread...
