Use Google to look for "two mode GM." Chrysler participated in a joint development effort for the "two mode" transmission.

GOOD LUCK!

not that simple... drivetrain contains many parts, one of which are hybrid components... for instance in the case of GM, R&D for batteries is done by battery manufacturer that wins the bid...

There must be some beancounter somewhere that has an idea. Try contacting Toyota USA, Chrysler, and or GM.

Hi ...dutch...,

If this is some kinda buisness class, please be sure to research the cost of not developing the hybrid car.

I studied design engineering, and can tell you these costs will vary widely across the board depending on the company, the size of the design team, the technologies being considered or developed, etc. There is a reason Nissan and GM wanted to lease hybrid technology from Toyota (and Nissan did)... because this can cost a fortune depending on the scope of the study.

Most hybrid drivetrain design alternatives have already been investigated and typically the series and parallel modes are greatly considered as of late. Much of the design alternative research is actually done in conjunction with many government laboratories, such as Argonne Nat'l Labs, the DOE, etc.

At this point, assume Li-ion or Li FeSO4 batts are available, so an OEM really only has costs of considering how size and piece together available components into a functional chassis. With current 'leading-edge' technologies and few companies producing the needed parts, the bigger expenses are found within supply chain managment. Also the costs of rigorous testing of the designed hybrid system of all selected elements pieced together. These later costs are similar to standard vehicles.

Why would a manufacturer make the real figures public?

There are companies can provide you with this kind of data or reports.
They are not free because it requires a lot of research, usually in tens of thousands of dollars per copy.
Don't expect anyone on this forum will give it to you free.
