BMW appears to be busy testing and developing their next-gen roadster after our spies were able to snap some new photos of the upcoming Z5 being driven at the Nurburgring.

The new roadster is still heavily camouflaged but our insiders were able to catch a glimpse of the Z5's interior. Based on the images, it looks like the Z5 will have a digital instrument panel and a 3-spoke steering wheel. Also seen is what looked to be covered-up iDrive display.

As far as the exterior is concern, BMW will continue to use a fabric soft top instead of a folding hard top.

In review, the Z5 is part of the BMW and Toyota's partnership in developing a rear-wheel drive sports car. Several days ago, the Japanese automaker was also caught testing what is expected to be the all-new Supra which is apparently slated for a 2019 release.

Both cars will be sharing the same platform and technologies, apart from the Supra's hardtop construction. In terms of powertrain, our spies suggested that the new Z5 and Supra will be available with a turbocharged four-cylinder or six-cylinder engine. A hybrid variant could also be made available once the automakers officially reveal both the Z5 and Supra.
