Tata Motors Ltd announced the details of the "Nano" minicar in Mumbai, India, March 23, 2009, disclosing the powertrain structure and the luggage compartment behind the rear seats (See related article).
The rear-mounted engine is angled backwards by 14° in line with the angle of the seat back. The vehicle was originally planned to be mounted with a 554cc 20kW (27PS) engine, but it was upgraded to a 624cc engine so as to improve the driving performance.
A cooling unit that looks like a radiator is seen behind the front bumper, but this is actually an air conditioning condenser. The radiator is mounted behind the engine and in front of the rear bumper.
We could not see the structure inside the hood (bonnet) because we were not allowed to open the hood. According to a company spokesperson, there is only a spare tire inside.
The luggage space can be extended by folding the rear seat back forward. The system for folding the seat back is standard equipment because the back door of the Nano can not be opened and the rear seat back has to be folded in order to load luggage in the luggage compartment. Tata says the Nano is a four-door vehicle, but loading/unloading from the luggage compartment is somewhat troublesome.
The highest-end LX model is equipped with front power windows, but the switches for them are not installed on the doors but right in front of the shift lever, which extends from the floor. The vehicle does not have any switches on the doors. So, this location of the switches was probably selected so that Tata Motors does not have to make significant modifications to the vehicle. However, the switches don't look very easy to use.
