India's [ Images ] top racing driver Narain Karthikeyan [ Images ] ended his season on a positive note, registering two victories -- a second and third place -- in one of the world's top race series.

The TATA RC motorsport driver and India's F1 hope thus ended the World Series by Nissan [ Images ] championship in sixth position.

The final of the World Series at Jerez, the former home of the Spanish Grand Prix [ Images ], on Saturday yielded a fifth position, in which Narain held off experienced Frenchman Tristan Gommendy.

Though Gommendy had a huge advantage of using a special set of brand new tyres, still he did not find a way past Narain.

It was a decent result for Narain despite being on this high-speed track for the very first time, whereas race winner Heikki Kovalainen [ Images ] had taken advantage of extensive testing there for the Renault [ Images ] Formula 1 [ Images ] Team, a statement from Tata RC said.

Race two promised a lot after Narain qualified finishing third on the grid, which was a good showing considering that his only chance to practice on the track was rained off on Friday.

Narain was running a steady third and closing on Monteiro before an error under braking cost him some time and put him out of the points and almost a certain podium slot, the statement added.
