New Delhi Bajaj Auto Ltd launched its first-ever four-wheeled vehicle on Tuesday, saying the RE60 would target commercial users and three-wheeled vehicle owners in India, and that production could involve Nissan and Renault.

The unveiling of the four-seater RE60 ended months of rumours that have buzzed around India's auto industry on the nature of the vehicle, which promises low carbon emissions and fuel efficiency, the company said in a much-anticipated launch.
