The circuit has been designed by renowned German architect Hermann Tilke and boasts the fastest straight-line speed of any F1 track in the world.
Indian Formula One driver Narain Karthikeyan, a member of the Spanish Hispania team, showered praise on the facility.
"I have raced on all the major F1 tracks across the globe and I rate this track as one of the best in the world," said Karthikeyan, who hopes to get a drive before the 100,000 fans who are expected to attend the race weekend.
The crowd will also be treated to other entertainment, including first-ever performances in the country by US heavy metal outfit Metallica and pop sensation Lady Gaga.
"We are trying to make the race a unique experience for the fans," said Gaur. "It is a question of India's prestige in the world. We have tried to make a small contribution to ensure that this investment is fruitful for all."
Gaur said tickets for the race were close to being sold out.
He also dismissed threats by some local groups of farmers to disrupt the race if their demands for better compensation in exchange for their acquired land were not met.
"We have worked here with complete co-operation from local people," Gaur said. "We are more than hopeful of hosting a peaceful race. It will be 100 per cent successful."
