In extremely hot and humid conditions, Ashwin Sundar of Team Speed-NK Racing yet again underlined his superior pace and skills by achieving a double in the Formula Rolon-Chevrolet class in the fifth round of the JK Tyre National Racing Championship on Sunday.

Ashwin, the 20-year old from Chennai who had cut his racing teeth as a 13-year old driving a Maruti Esteem car in the Saloon car races at the MMRT track here, was in a league of his own from start to finish to replicate his commanding win in the first race Saturday night.
