“We weren’t chasing headlines today. It was all about learning and recording data as part of our preparation for our Le Mans debut,” Team Principal and Technical Director, Ben Bowlby said.
“At the end of the day our times in the damp conditions were competitive and during the morning runs we recorded the two fastest straight line speeds overall.
“We know we have a big learning curve ahead of us bringing this unique front-engined, front-wheel-drive car to Le Mans but after our first day here we have three straight cars in the garage and mountains of data for our engineers to study.”
