The new BMW Z4 has been officially teased for the first time, with a single, shadowy image of the new sports car, plus a promised unveiling next month.
The new Audi TT and Mercedes SLC rival will make its debut on 17 August. While that rules out a Frankfurt Motor Show reveal, it matches up nicely with the 2017 edition of the Pebble Beach Concours d’Elegance and Monterey Car Week.
