GM Powertrain Evolution
GM Powertrain traces its history to the myriad of automotive companies that combined to form GM in 1908. These companies included: Chevrolet, Pontiac, Buick, Oldsmobile and Cadillac. For many decades, each division produced its own engines and transmissions. In time, it became evident that efficiency improvements could be made with increased administrative and manufacturing cooperation between all divisions. The consolidation began in 1983, with the assignment of the Toledo, Ohio Chevrolet and the Windsor, Ontario GM of Canada transmission plants to the Hydra-Matic division. The "marriage" of the Hydra-Matic and GM Engine divisions in 1990, resulted in GM Powertrain. The subsequent addition of Central Foundry Division and Advance Engineering Staff in 1991, elevated Powertrain to corporate group status. In 1997, the formation of a GM global powertrain organization was announced, encompassing all of GM's powertrain engineering and manufacturing activities outside of North America. In 2010 Powertrain and the vehicle organization were joined, creating Global Product Operations.
GM powertrain is not chevy, never was. You can try and twist it any way you'd like and it still will not come out the way you want it. This is right from GM powertrains website.
Doesn't say they're chevrolet and chevrolet is GM powertrain does it? It says that GM powertrain supplies automotive manufacturers with powertrain parts. It also states that they have 86 plants in 17 countries, so much for them being in chevys plant huh?
It also definitively states that they have become a separate corporate group. They are separate entities as I've already said. I see your doing research at 3 in the morning, lots of misspelling on the post, were you drinking when you posted this?
I'm much more confident reading the information directly from the source of GM powertrains website that maintains they are indeed a separate corporate entity, as I've maintained from the beginning. They supply the separate divisions with engines and transmissions and independently design their own offerings. They also offer marine powertrain as well as industrial powertrain.
Chevy performance is marketing name for selling what was previously GM Goodwrench performance parts. The chevy name is more recognized than GM Goodwrench was, the reasoning behind the name switch. As I've already pointed out they also market the cast aluminum Stratostreak valve covers with Pontiac on the covers. They are the aftermarket division for items to enhance the stock offerings from all GM divisions, GMC truck, Cadillac and Buick.
Also Wikipedia is NOT always a reliable source since anyone can have input into their definitions and information. I seldom take anything from Wikipedia as gospel and have found many mistakes in their flawed information.
Harley Earl was a renowned designer of the GM bodies, I have no knowledge of him designing any engines for any GM division. Upon further checking his biography there is no mention of him designing anything engine related in his career, only doing coachwork for GM of which he was a master. Your stories are so flawed no one can take you seriously.
