Young brains of Tata Motors have displaced many long extablished standards of automobile technology in their endeavors to curtail the size, weight and price of Nano. No other motor car’s engine has better power-to-weight ratio than Nano’s engine. It is made from aluminum instead of steel and seeing Nano’s low slung back seat one wonders how the engine was accommodated beneath it.
There is no room for battery in Nano’s engine compartment at the rear end of the car. If it were to be placed in the front under the bonnet a long length of copper wire would be required to connect it with the engine adding to the cost of the car. Hence, by placing the battery beneath the driver’s seat economy has been effected in both the cost of wire as well as space under the bonnet.
No part of Nano’s body has been welded because welding is not only expansive but also slows down production. Therefore, chemical adhesives have been used for the joints. Do not think that chemical joints are short-lived; framework components of giant airliners like Airbus-380 are also joined with adhesives.
Spare wheel in the luggage compartment beneath the bonnet is somewhat smaller than the regular wheels. The experts at Tata Motors thought that since spare wheel was going to be used only occasionally, a smaller wheel might serve just as well. By reducing its size the engineers also reduced the overall weight of the car to some extent which was their basic objective.
There is only one wiper and only one wing or side mirror on the driver’s side. Only three bolts hold the wheel together with axels instead the usual four. The fuel tank has only 15 liters capacity. There is no power steering because there is no engine in the front to press the wheels down with its weight.
