Technical specifications

According to Tata Group's Chairman Ratan Tata, the Nano is a 33 PS (33 hp/24 kW) car with a 623 cc rear engine and rear wheel drive, and has a fuel economy of 4.55 L/100 km (21.97 km/L, 51.7 mpg (US), 62 mpg (UK)) under city road conditions, and 3.85 L/100 km on highways (25.97 km/L, 61.1 mpg (US), 73.3 mpg (UK)). It is the first time a two-cylinder non-opposed petrol engine will be used in a car with a single balancer shaft. Tata Motors has reportedly filed 34 patents related to the innovations in the design of Nano, with powertrain accounting for over half of them. The head of Tata Motors' Engineering Research Centre, Girish Wagh has been credited with being one of the brains behind Nano's design.

According to Tata, the Nano complies with Bharat Stage-III and Euro-IV emission standards. Ratan Tata also said, 'The car has passed the full-frontal crash and the side impact crash'.

History and conception

The project to create the world's most inexpensive car began in 2003, under the Chairman of Tata Motors, Ratan Tata, inspired by the number of Indian families with two-wheeled rather than four-wheeled transport. The Nano's development has been tempered by the company's success in producing the low cost 4 wheeled Ace truck in May 2005.

Contrary to speculation that the car might be a simple four-wheeled auto rickshaw, The Times of India reported the vehicle is "a properly designed and built car". The Chairman is reported to have said, "It is not a car with plastic curtains or no roof — it's a real car."

To achieve its design parameters, Tata has refined the manufacturing process, emphasized innovation and sought new design approaches from suppliers. The car was designed at Italy's Institute of Development in Automotive Engineering — with Ratan Tata requesting certain changes, such the elimination of one of two windscreen wipers.


The Nano has 21% more interior space and an 8% smaller exterior, when compared with its closest rival, the Maruti 800. The car will come in different versions, including one standard and two deluxe variants. The deluxe version will have air conditioning, but no power steering. The car is expected to be produced in the Singur plant in West Bengal, which is under construction. The initial production target set by Tata Motors is 250,000 units per year.

Tata Nano

The Tata Nano is a proposed city car first presented by India's Tata Motors at the 9th annual Auto Expo on January 10, 2008 at Pragati Maidan in New Delhi, India.

While currently undergoing final development, the Nano is projected to be a small, affordable, rear-engined, four-passenger car aimed primarily at the Indian market.

Newsweek identified the Nano as a part of a "new breed of 21st-century cars" that embody "a contrarian philosophy of smaller, lighter, cheaper" and portend a new era in inexpensive personal transportation — and potentially, "global gridlock" . The Wall Street Journal confirms a global trend toward small cars, which includes the Nano.

The prefix "Nano" derives from the Greek root 'nanos', meaning dwarf — as with nanometre. "Nano" also means "small" in Gujarati, the native language of the Tata family, founders of the Tata Group.
