Ganassi IndyCar duo Scott Dixon and Dario Franchitti will team up in a second Chip Ganassi Racing with Felix Sabates Daytona Prototype for the Grand-Am round at Laguna Seca.
The pair will drive the #2 Dinan-powered BMW at the September 7-8 event, backed by Cessna as part of the company's broader relationship with the Ganassi team.
They will run alongside the #1 car driven by Ganassi's Grand-Am regulars Scott Pruett and Memo Rojas.
"This is a special opportunity for our Daytona Prototype programme," said Chip Ganassi Racing Teams president Steve Lauletta.
"Any time you can pair two of the best IndyCar drivers out there in the same car makes for an immediate contender."
Laguna Seca will be Franchitti and Dixon's second Grand-Am appearance of the season, following on from their participation in the Daytona 24 Hours earlier in the year.
