Chevy Bolt not on shared architecture, but platform name secret

 

http://www.greencarreports.com/news/...secret-gm-says

Despite what would appear to be much misreporting by industry sources, GM says the Chevy Bolt EV
does not share any elements of those vehicles' small-car architecture, which was developed by its Korean small-car team.

 

"There are no Bolt EV parts tied to the G2 architecture," said lead product engineer Josh Tavel, via e-mail through GM communications.

 

 

 

UPDATE: After this article published, GM's Kevin Kelly gave us the following statement that appears to explain the discrepancy: "The Bolt EV program originated on the Gamma architecture, but then grew into its own architecture—even as it maintained the G2 code."

that is interesting.

 

I wonder how many or the % of parts by value are shared with Gamma?

Sounds a lot like DEW>D2C (In terms of starting with a platform and essentially ending up with a new platform).

A better analogy would be Mustang S197 ---> S550.

 

Some people get hung up on the idea that every new product has to come from a clean sheet design

but there's a lot of advantages to using an existing vehicle platform as a starting point.

A true derivative has to share less than 50% of its components with the originator of the platform

otherwise its not much better than a top hat change. Bolt it more than just a derivative of Gamma

so the share is probably down to 25% or maybe less..

 

When you change, the body, floor pan, power train, suspension and electrical system

all the existing starting points have changed, I suspect the only thing that Bolt has in

common with Gamma is the build process.

 

It seems like GM suppliers like LG had a bit of influence in the design of Bolt which is probably

why the platform changed so much and was separated from the Gamma family. Gamma was

probably a good starting point to evolve the design in the right way and cust months off the

development time.
