The 21-year-old from Kuala Lumpur enters his second season with the reknown German team, following a year in the domestic F3 Cup in 2014.
Team principal Timo Rumpfkeil was keen on Jeffri, who had already contested straight-line tests for a Formula One team as a 16-year-old back in 2010, to join his outfit for the move up the Formula Three ladder.
"We saw last year that Nabil has a lot of potential,“ says Rumpfkeil. "He has taken in every information he could get, and he showed a lot of progress throughout the year.
I’m sure we can unlock more speed and competitiveness from him in 2015. Both he and the team will benefit from the fact that they gelled together very well last year. Now it’s time to harvest.“
Nabil Jeffri: "I look forward to making the next step on the motor-racing ladder with a team like Motopark. I enjoyed the testing sessions with the Motopark team who made sure I would be comfortable driving the car and were with me in every step. FIA Formula 3 European Championship would be a challenge for a young rookie like me and I plan to give my best , focussing on every race."
