BMW has released its first teaser of what is likely the replacement for the now-retired E89 Z4 roadster. The carmaker didn’t provide much in the way of details, merely stating all will be revealed on August 17 ahead of the Pebble Beach Concours d’Elegance.

The sketch shows a roadster with a sleek silhouette, long bonnet and pointed nose – all cues that are consistent with prototypes seen in the past. However, whether BMW will show the production version or merely a concept of its new roadster at Pebble Beach, we’ll have to wait and see.

The yet-to-be-named roadster is the product of a joint venture between BMW and Toyota to jointly develop sports cars, with the Toyota camp prepping what should be a Supra successor. Both cars will ride on a new platform, and are claimed to be rear-wheel drive with some form of hybrid power to boost performance.

Where the new BMW roadster will come with a folding soft-top, its Japanese “brother” will instead be a dedicated coupe. Obviously, each will gets its own distinct styling, which is made clear when looking at spyshots of both cars undergoing testing together.
