Porsche’s fractious Formula E team-mate situation took another unhappy twist with a bizarre collision between Pascal Wehrlein and Antonio Felix da Costa in opening practice at Berlin Tempelhof on Friday.

A rear-end hit from Wehrlein at the final corner in the closing minutes of the session sent da Costa’s car into the wall on the pit straight, causing significant damage. Wehrlein continued unscathed, and was fastest in the session.

Da Costa had been told on team radio that Wehrlein was preparing for a flying lap, but Wehrlein then “stopped in the last corner” in da Costa’s eyes and he moved back in front, with Wehrlein then hitting him on the way onto the straight.
