Hilmer Motorsport will not field any drivers in Sochi this weekend.
The German team will be missing its second event of the season after electing to sit out the first weekend in Bahrain back in April.
Hilmer has also run only one car in the previous two race meetings in Belgium and Italy. Nick Yelloly and Simon Trummer were at the wheel of the #24 Hilmer car in the respective events.
Trummer was unable to drive for the team this weekend due to prior commitments in the World Endurance Championship at the Fuji Speedway, Japan.
