Sorry, I have not read this entire thread (started Oct. 2015) so this may have been mentioned before and probably more than once. Tesla R&D expenses from 2010 - 2016 = 7 years and the TOTAL <$5 billion.
GM buys back $16 billion of GM stock.
GM sells Opel for about $2 billion - does it go into R&D? no - went to shareholder value, dividends.
Dividend History
GM R&D 2015-2016-2017 = $20 billion
This is R&D for 2015
VW $15.3 billion
Toyota $9.2 billion
Daimler $7.6 billion
GM $7.4 billion
Ford $6.9 billion
Honda $5.5 billion
BMW $5.5 billion
Nissan $4.6 billion
Denso $3.6 billion
FCA $3.4 billion
I just don't see the shift to electrification being reflected in R&D - OR they sure aren't getting results.
You can obviously do a more thorough research job for better/more details.
Too bad I didn't find this thread years ago.
