The actors, who were here Monday to promote their forthcoming film "Tezz", took everyone by surprise with their stylish entry.
Both the actors tried their hands on the Italian super sports car and were fascinated by its speed on the 5.14 km-track, which was developed for the country's inaugural Formula One Grand Prix last year.
"The highest speed at which we drove today was 260 kmph. I've never done such an act before in my life," Anil told reporters here post the casual race, in which Ajay was faster.
"It's like an addiction! We drove four laps and still wanted to do more. This track is simply amazing and very smooth," added the 52-year-old.
Looking comfortable in a blue checked shirt and wayfarer shades, Ajay said: "This is the first time that someone from Bollywood has come up with the idea of promoting a movie on a racing track. It's very exciting yet innovative."
"Tezz", releasing Friday, also features Zayed Khan, Boman Irani, Sameera Reddy and Kangna Ranaut. It is directed by the maverick Priyadarshan, whose showbiz career spans close to three decades.
Known for his comedy flicks, the filmmaker says he wanted to try something new. That's the reason why he thought of directing an action thriller this time.
"It's a social drama, thriller and is about a chase between cops and criminals. This is the 84th film of my career. I've put all my experience in this movie. The movie also has a thin line of emotions, something similar to 'Deewaar' and 'Sholay'," Priyadarshan, who was also present at the track, said here.
