Cairoli, Dienst join Dempsey-Proton Porsche WEC line-up

Dienst and Cairoli, who are both newcomers to WEC, will partner team boss Christian Ried in the #77 GTE-Am class Porsche 911 RSR.

Italian driver Cairoli, 20, is part of Porsche's junior programme, having joined after winning the Porsche Carrera Cup Italy championship in 2014.

Last year, he went up against fellow Porsche junior Sven Muller for the Porsche Supercup title, eventually finishing runner-up.

Dienst, who turned 20 three days ago, was German series ADAC Formula 4's inaugural champion two years ago, seeing off BMW junior Joel Eriksson and Joey Mawson.

He drove a Porsche 911 GT3 R for Team Schutz in ADAC GT last year.

Dempsey-Proton had entries in both GTE WEC classes last year, but has scaled down to one car, which has moved to GTE Am following the works squad's return.
