Hi friends now I am tell you Tata Nano has not a powerfull engine The engine is matted a 4 speed manual transmission.its a not comfortable car its not for full family and it capacity of a 0.6L, MPFi, twin cylinder motor is used, which displaces 624cc, But even she did not like it much, it’s not that comfortable to ride. City roads with full of traffic and Air condition on mileage not what it is written on various sites and manuals I hardly get around 15km/liter. Poor interior inside also another reason to dislike it. Better try something different.
