Team Engstler will again run Charles Ng alongside team owner Franz Engstler in the World Touring Car Championship this year
Engstler and Ng finished 12th and 25th in last year's standings and fourth and 16th in the Independents' Trophy.
Engstler was however, denied a chance to add to his Oschersleben win from 2011 when Yvan Muller spun him out of the lead during the Sonoma reversed-grid race last September.
Team manager Kurt Treml said, "We are confident that both drivers will be able to improve their results.
"Franz is an experienced driver who even managed to claim an outright WTCC victory two years ago at Oschersleben, while Charles has got to know the championship by serving his apprenticeship during his first full season in WTCC."
The German team will again field a pair of BMW 320 TCs, which will be eligible for the Independents' Trophy.
