General Motors India, the wholly-owned subsidiary of US automobile major, has signed on leading Bollywood stars Saif Ali Khan and Rani Mukherji to endorse its muchawaited mid-sized sedan Chevrolet Aveo.

In the advertisement, the two stars take the car out for a spin and by the end, the car's stellar performance has given the actors a bout of performance anxiety! It seems like a fun twist in the tail.

Tells Saif, "I was excited about doing the Chevrolet ad because in the car segment, it's one of the coolest brands. The tagline for Chevrolet is also 'when good is not good enough', which is something I'd like to associate with, and it's a philosophy I share with my work."

With this Rs 4 crore ad, Chevrolet hopes that when the Aveo rolls out in this month, audiences will find the brand accessible, thanks to Rani and cool, thanks to Saif.

"The Chevrolet Aveo is a new generation car with class leading performance, amazing looks and style and great mileage. Hence, we were looking at ambassadors who not only connect emotionally with the audience but also embody the two dimensions of performa nce and aesthetics, substance and style plus class and exuberance," General Motors India President and Managing Director Rajeev Chaba said.

The Aveo, which is expected to take on the Ford Fiesta and Honda City, is seen as a car with segment defining performance, great looks and styling, space, and fuel efficiency. This car is primarily aimed at upgraders from the 2 box as well as additional 3 box car owners.
