Vettel will take the wheel of the 963, which Porsche runs in collaboration with American powerhouse Penske, at a 36-hour test at MotorLand Aragon in Spain.
The 36-year-old German has already turned his first laps of the prototype at Porsche's Weissach base following extensive simulator running.
“I’m looking forward to testing the Porsche 963. I already got the chance to get a feel for the car during a rollout in Weissach,” said Vettel.
“I’ve always followed other racing series and my curiosity for endurance events encouraged me to just give it a shot. Now I’m excited about the long run in Aragon and I’m looking forward to my time behind the wheel.
"It’ll definitely take an adjustment and some getting used to but everyone in the team is very open and helps me. This will be a new experience for me."
Porsche Motorsport vice president Thomas Laudenbach revealed Vettel had asked him if there was an opportunity to join a test, with Porsche more than happy to accommodate him.
“We’re delighted that Sebastian Vettel is interested in our Porsche 963,” explained Laudenbach.
“There was no question for us that we’d be thrilled to support his request for an opportunity to test and provide him with extensive preparation and plenty of time to drive our hybrid prototype."
