Ahead of this year’s Pebble Beach Concours d’Elegance, BMW has dropped a teaser image of a new roadster concept that will be revealed on August 17. This is the second teaser of what is reportedly known as a preview for the next-generation Z4, the result of a joint venture between BMW and Toyota.

The car (partially) shown here isn’t short of theatre, at least when it comes to styling. The front features a more contemporary take on the brand’s twin kidney grille, leading into a long, sculpted bonnet. We also see some angry-looking headlights, with the familiar corona LED rings within them.

Elsewhere, the concept’s fender vents (Air Breathers in BMW lingo) feature lines that lead into the muscular haunches, passing by the slender wing mirrors. A rakish windscreen and supports behind the headrests are also part of the overall getup.

As stated earlier, the new BMW roadster was developed together with Toyota, with the Japanese firm prepping a “Supra successor.” While both cars are said to ride on a same platform, each will get their own distinct styling and powertrains, according to reports.

Any further details about the ‘Z4 Concept’ will only be revealed on the above-mentioned date, but BMW has said a production version of the E89 replacement will arrive next year.
