It was announced several German manufacturers and Japanese manufacturers plan to bring out new Hydrogen electric cars by 2020. We know the Model S got the Germans attention with several CEO's commenting about Tesla. So the M3's 274000 in the first 3 days - must be a slap in the face right? Surely CEO's of the Japanese and German manufacturers would of already discussed Tesla's M3 success by now and im confident they already adjusting there future R&D strategy to target Tesla. Hydrogen wasn't doing to well before the M3 reveal and now that Tesla have proven BEV's are the future why would you invest 100's of million into Hydrogen? Smart thing would be Hydrogen to be canceled first and a % of R&D taken away from Fossil fuel cars and go in BEV's with a top team. After wise in 10 years from now the stubborn manufacturers that don't do that can join the Blackberry stubborn club don't you think?.
