The Tata Nano is a rear-engined, five-passenger city car built by Tata Motors, aimed primarily at the Indian market.
Tata has sought to produce the least expensive production car in the world aiming for a starting price of Rs.100,000 (approximately US$2,000). Tata Motors commercially launched Nano on March 23, 2009, with bookings from April 9 to April 25.
Price
Tata initially targeted the vehicle as "the least expensive production car in the world" aiming for a starting price of 100,000 rupees or approximately US$2000 (using exchange rate as of March 22, 2009) despite rapidly rising material prices at the time.
As of August 2008, material costs had risen from 13% to 23% over the car’s development,and Tata faced the choice of:
- introducing the car with an artificially low price through government subsidies and tax-breaks, or
- forgoing profit on the car, or
- using vertical-integration to artificially boost profits on cars at the expense of their materials industries, or
- partially using inexpensive polymers or biodegradable plastics instead of a full metal-body, or
- raising the price of the car
Subsequently however material prices dropped dramatically as a result of the financial crisis of 2007–2009.
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 balance 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 project head, Girish Wagh has been credited with being one of the brains behind Nano's design.
Rear mounted engine
The use of a rear mounted engine to help maximize interior space makes the Nano similar to the original Fiat 500, another technically innovative "people's car". A concept vehicle similar in styling to the Nano, also with rear engined layout was proposed by the UK Rover Group in the 1990s to succeed the original Mini but was not put into production.[56] The eventual new Mini was much larger and technically conservative. The independent, and now-defunct, MG Rover Group later based their Rover CityRover on the Tata Indica.
Tata is also reported to be contemplating offering a compressed air engine as an option

Diesel
Together with Diesel Engine specialist FEV Tata Motors is developing a 684 cc diesel engine for the Nano. It was earlier reported by media that Tata was producing an 800 cc Common Rail diesel engine. Diesel Variant will be available in September, 2009. Diesel variant Nano will sell for Rs2 lakh (200,000 rupees). Nano will have the smallest Common Rail Turbocharged Diesel engine in the world.
