While BMW is parading the Concept Z4 at the 2017
Pebble Beach Concours d'Elegance, another prototype of the upcoming roadster
has been spied on the Nurburgring.
It continues to be dressed in camouflage, which
makes it kind of hard to spot any significant styling upgrades, but the new
folding soft-top, which will be used instead of the current models' folding
hardtop roof, is visible.
The new Z4 will share the same platform with the new
Toyota Supra, which is also in development. Earlier sources talked about carbon
fiber and aluminum being used in the architecture of both cars, while the
German model should employ turbocharged four- and six-cylinder units. A hybrid
could also join the lineup, at a later date.
BMW is expected to launch the all-new Z4 sometime
next year, with the first examples arriving at dealers by the end of 2018.
