The stewards gave Lotterer a penalty for causing a collision with de Vries at Turn 8, which bumped the Porsche driver down from his ninth-place finish and out of the points - thus promoting Sam Bird to ninth and Sebastien Buemi into 10th.
The German driver contended that there was an earlier incident between the two at Turn 1, explaining that de Vries squeezed him on the exit of the corner which resulted in contact.
