The Coimbatore-based Narain, supported by Kingfisher, Mobil 1, Tata and JK Tyre, overtook Brazilian Luciano Burti who was in pole position, by taking an outside line for the first corner, a right-hander, and never looked back, according to information reaching here.

A major crash at the back of the field on Lap 3 saw the next four laps run behind a Safety Car, and thereafter, Narain again pulled away to win.

Narain's success on Sunday provided a double for Carlin Motorsport's boss Martin Stone and Trevor Carlin, as team-mate Mike Bentwood, who finished 10th overall, was first in the National class.
