CR18's first official day of testing started in June under cloudy skys down in Cardiff Bay. This was the first opportunity to have the full aero package attached to the car and test that it produced the handling we desired from it. Day 1 was all about getting the miles in to dial out any issues with the car or with the set-up of the car. The test went smoothly until a reliability issue with the controls meant we had to cut our day short.
