Back in January of this year, BMW and Toyota signed an agreement
to cooperate on joint development of a fuel cell system, joint development of architecture and components for a future sports vehicle, collaboration on powertrain electrification and joint research and development on lightweight technologies. The two companies have now decided upon and agreed to develop a joint platform for sportscars, BMW's development chief Herbert Diess told a German newspaper.
"We have agreed on a joint architecture for a sports car. What is important is that there will be two different vehicles that are authentic to the two brands," Frankfurter Allgemeine Zeitung
today quoted Diess as saying.
Diess declined to provide details on the models that would result from the cooperation, but much of the rumor mill surrounding this project since its inception has suggested a potential Supra and Z4 built on the shared platform.
from earlier this year reported that BMW was testing a BMW-built V6 hybrid motor which would deliver similar power to the new Supra - speculated to be 400+ HP (from a turbocharged 2.5L inline 4 cylinder hybrid or a mid-mounted 3.5L V6 hybrid). Another recent rumor
suggested instead that a hybrid halo sports car would be the product of the collaboration.
The next Z4 is due 2015-2016.
