Three-time DTM champion Rast set a best time of 1m37.077s on the second and final day of the running at Hockenheim to top the timesheets ahead of Schubert Motorsport team-mates Sheldon van der Linde and Marco Wittmann.
Most of the test’s quickest laps were set during the final session on Wednesday afternoon, which was also the longest of the two-day test at three hours and 55 minutes. The weather was also more optimal on Wednesday, with overcast conditions giving way to a bright sun as asphalt temperature reached 31C.
