***While lap times were not recorded, van der Zande said he was pleased with his first impressions of car and predicts it will be a step forward in performance and reliability. “We didn’t even [focus] on any lap times,” he told Sportscar365. “We got a good feeling for the car, the systems and it felt pretty good.”
