I GT klassen er det som før nævnt Jan Magnussen og Oliver Gavin der er hurtigst. Søsterbilen er over et sekund efter. BMW'erne fra Team RLL plejer at være dominerende i denne klasse, men er efter den første session et sekund efter Jan Magnussen og Oliver Gavin.

I GTC klassen er der ALMS debut til David Heinemeier Hansson hvor han i dette løb kører sammen med Dominik Farnbacher. David Heinemeier Hansson har indtil dette løb, kørt i IMSA GT3 klassen, og skal lige vænne sig til en del ting som er anderledes i ALMS i forhold til IMSA klassen.
