BMW’s new Z4 Concept is set to make its world debut at the Concours d’Elegance in Pebble Beach today, but the official images of the roadster have been leaked, the reveal being made via Bimmerfile.

The car displays elements of the new design language seen on the Concept 8 Series study, with an outline offering a distinct wedge shape. Styling cues include a short bonnet and overhangs, placing the driver closer to the centre of the vehicle than in the E85 and E89 Z4s.

The concept – which sits on 20-inch twin five-spoke wheels – wears an Energetic Orange frozen exterior paint finish, which the automaker says helps accentuate the three-dimensionality of the exterior in a big way.

The study is effectively a preview of the next-generation Z4, which is being developed together with Toyota – the Japanese company will also have its own car from the joint venture project, a new Supra.

Reports indicate that both cars will share the same platform as well as elements such as the suspension layout, but will feature their makers respective powertrains and drivetrains. Word is also that the BMW will only be offered as a drop-top, and the Toyota a coupe, to keep both offerings distinct.

The production version of the E89 replacement is slated to go on sale next year.
