Handling a Formula Car introduced in India for the first time, Vishnu's victory in all the three races had put him in the leadership position on point table with 115 seven points ahead of Hyderabad's Akhil Kushlani, who had a miserable performance this weekend after having won the three races in the first leg last month.
Bangalore's Akhil Rabindra was on third spot with 56 points.
Sarosh's strong rivals Saran Vikram and Vishnu Prasad were hit after the corner-2 by Karthik Krishna (Dark Don) and their cars spun and prevented them from racing. At the end of the race, Karthik Krishna finished third but was relegated to eighth spot after he was penalised 30 seconds for the infringement.
The incident forced the race to be red flagged and the winner and other placing were decided on seven laps as per the new rules of the championship.
