Bamber's crew have a different task.
After comprehensive testing, they now have to get used to all the racing procedures, will experience the excitement of their LMP1 race debut, and get ready for Le Mans, the season's highlight.
"From last year I have very fond memories of Spa. It was great fun to win the Porsche Mobil 1 Supercup race there from pole position. I love this circuit, as it is a spectacular place," Bamber said.
"I am so looking forward to taking the 919 through Eau Rouge and, anyway, I can't wait to race that car.
"When the Silverstone race was on I was glued to the screen. It was one of the best races I have ever seen," he said.
"It was like a six-hour Supercup race. I enjoyed working with Nico and Nick in testing and now I'm really looking forward to racing with our car crew for the first time."
The challenging Circuit de Spa-Francorchamps lies in the mountainous Ardennes region in the south of Belgium.
The lap length of 7.004 kilometres is above average and the track features a number of exciting high-speed sectors. The hybrid drivers are especially stretched on the long uphill sections.
The daunting compression of Eau Rouge and Raidillon fills racing drivers of all categories with awe. Because of the track's length it may well rain on one part of the circuit while other parts are still dry - a particular feature similar to Le Mans.
In 2014 the winner did 171 laps.
