Nano with $10 airbag SO what if it is the cheapest production car in the world? Ratan Tata wants to ensure that the Nano is also one of the safest and he has asked Autoliv FB to develop a $10 airbag for the People's Car. Developing these airbag will be a challenge for Autoliv as airbags cost about $150 for compact cars like the Zen Estilo. Nano is likely to have two front airbags in its top end versions.
