Narain faced stiff opposition from Italian GP2 driver Kevin Giovesi and his Super Nova teammate Vittorio Ghirelli, who started with the Indian from the front row.
But the Indian always seemed to have enough in hand to keep the Italian duo at bay and managed to cross the line in the top spot 23 laps later.
"It feels great to win at Nurburgring - it is a historic venue and it was amazing to hear the Indian national anthem playing in front of packed grandstands," an elated Narain said.
After leading from the start and opening up a nearly two second gap, Narain pitted on lap 18 for the mandatory tyre change, and the Super Nova crew executed a near-perfect pit-stop to ensure that he maintained his advantage.

"I was praying for decent stop as I haven't had the best luck in the pits this year, but the guys really nailed it this time," he said.
"We are closing the gap to the leaders but we need some solid points tomorrow as well to make further progress. Starting eighth [as per reversed grid] it won't be easy but I will try to keep my nose clean and finish as far up ahead as possible," remarked Narain.
