At the 2015 Geneva Motor Show, Klaus Frohlich, BMW head of R&D told the press that not only a Z4 replacement is in works, but also confirmed that it will be developed together with Toyota. The two companies have been working on three sports cars for years now.

BMW and Toyota have been tight-lipped about details but the two companies say their partnership will last until at least 2020. The rumormill churned out that two Z4s are in works – a coupe and roadster.


Now, a new report says the proposed Z4 coupe is gone. Toyota will sell only the hardtop version and BMW will stick with the roadster. Just a few months we’ve seen the first Z4 Roadster prototypes being tested in the snow.

What remains unknown is whether BMW will call the new soft-top the Z5 or stick with the current nomenclature.

BMW also plans a top-of-the-line Z4 M with 450-hp from an inline-six, whereas the ultimate Toyota Supra will be powered by a twin-turbocharged V6 from Japan.

The next Z4 or Z5 Roadster will arrive in 2018.
