The Swiss driver takes advantage of the WTCC summer break to race in the Belgian endurance race, sharing the car with Frey Lorenz and Gabriele Gardel for an all-Swiss driver line up.
“I am really looking forward to Spa with its special atmosphere and the outstanding participants," he said.
"According to the official tests and two days of testing at the Lausitzring we are well prepared. Spa is one of my favourite tracks.
"Our own project, the Emil Frey GT3 Jaguar, after a six-month development phase is making very promising progress. It is therefore important that at Spa we not only achieve a positive result in the race, but also learn from the experience so we can apply it to our own project."
