Bollywood seems to have gone green.

After news that Akshay Kumar [Images] is driving a Reva -- a car that runs on electricity -- comes another bit of news that Ajay Devgan [Images] has gotten himself a Maruti [Get Quote] Swift.

Apparently, small cars like the Swift consume lesser petrol, prompting the environmentally conscious actor to change gears.

Besides, in the heavy Mumbai traffic, all cars -- whether big or small -- run at a snail's pace. So a big car may suit a star but will do nothing to make him reach his destination faster.

Interestingly, Ajay's father Veeru Devgan -- a veteran fight master in the Hindi film industry -- prefers a motorcycle to a car in order to avoid the Mumbai traffic.
