Stevenson Motorsports has confirmed Connor De Phillippi and Dion von Moltke as its third drivers for the Mobil 1 Twelve Hours of Sebring, as part of a slightly adjusted lineup in its two Audi R8 LMS entries.

De Phillippi joins Andrew Davis and Robin Liddell in the team’s No. 6 Audi, which will mark the young American’s first 12-hour start at Sebring. He has past experience at the track from his open-wheel career.

He enjoyed a standout drive at the Hankook 24 Hours of Dubai, also in one of the new Audis.

“For 2016 I was looking to make a return to more racing in North America, and as my European plans developed I tried to align myself with top teams that would be competing in the new Audi GT3 machinery,” he said.

“Stevenson Motorsports was at the top of my list, and after we made contact it all moved forward from there! The 24 Hours of Dubai was my first time in the Audi, and starting off with such a strong personal performance in completely foreign machinery gives me a great feeling heading into Sebring.”

Von Moltke, a past Sebring class winner, continues as third driver in the team’s No. 9 car along with Lawson Aschenbach and Matt Bell. He’s also confirmed for Petit Le Mans with the team, although the car is to be determined.

”To be able to join Stevenson for the famed trio of races, the Rolex 24 At Daytona, the Sebring 12 Hour and Petit Le Mans, is very special,” von Moltke said.

“To be able to go from one great team in Paul Miller Racing, to another stellar team in Stevenson Motorsports is something I cherish as a driver. I want to be battling for wins and championships and on a team like this I know I’ll have the support to allow me to do so.”

Aschenbach and Bell move back to the No. 9 car after racing with Davis and Liddell at the Rolex 24 at Daytona.

The No. 9 car finished eighth in GT Daytona at Daytona with von Moltke, Tristan Vautier, Boris Said and Kenny Habul, while the No. 6 car finished 15th.
