One of the sources from within BMW has revealed that the company will soon reveal a concept co-developed with Toyota which will pave the way for the Z5.
BMW and Toyota had in the beginning of the year announced a collaboration to work on a new sports car. Taking this ahead, a source within BMW has stated that we will get to see a concept co-developed by the two companies and it will serve as a preview for the rear-wheel drive Z5 Roadster.
BMW would be in charge of creating the exterior and interior design of the car which supposedly would take cues from the Vision ConnectedDrive concept. They will also supply the engines and implement carbon fiber reinforced plastic (CFRP) construction. Toyota will provide the optional hybrid technology.
The source further indicated that a coupe will follow the roadster, along with Z1 and Z3 models using the UKL front-wheel drive platform which will be also again created in collaboration with Toyota. There were plans for an M version of the Z4 but the car was axed just before being given a final go ahead. However, BMW could decide to launch a limited edition like they did with the 1-Series M Coupe.
