The Noida-based veteran rallyist and his navigator Ajay Kumar were virtually unbeatable on each of the three days, conquering eight of the 10 stages to pocket a major chunk out of the total prize money of Rs 10 lakh.
On the third and final day too, he won the first three special stages before easing up on the last one.
He finished all the stages, including the super special stage on day one, in just over an hour to win with an impressive 27 second lead.
"But as a driver I am more comfortable in the hills, especially where it's more about technique than speed, and I guess that's where I scored," he explained.

Amanpreet, who owns one of the largest rally car workshops in India, gave all the credit to his 1300cc turbo charged Gypsy.
"I worked on it for three months, and was managing to produce close to 150-odd bhp power that is pretty good for a gypsy. I guess that was the only good and best part of my car - the engine," he said.
He finished all the stages in an equally commendable one hour and 29 seconds.
Delhi's Sandeep Sharma held on to his position to take the third place. His feat was particularly laudable as he was driving a stock car, and it was clear on the second day itself that he was struggling.
Maninder, wife of Sandeep Sharma and the only lady driver in this category, slipped from her second place to finish fourth.
