A six-car train of cars headed by Tiago Monteiro disputed fifth place.
The former grand prix driver's factory Honda team-mate Gabriele Tarquini provided the only passing manoeuvre in the group, benefiting from Zengo Honda driver Mehdi Bennani running wide at the Nockstein-Kehre on lap five to take eighth.
The gaggle was separated by under four seconds at the chequered flag, with Coronel's ROAL team-mate Tom Chilton completing the top six.
After sustaining heavy damage to his Campos Chevrolet in a practice crash that sidelined him from qualifying, Hugo Valente defied his post-shunt prediction by starting from the rear of the grid.
Sadly, the Marrakech podium-finisher and team-mate Dusan Borkovic would both pit for attention on the second lap.
