The car was successfully 'homologated" by the Pune-based ARAI, which handed over the Nano"s clearance certificate to Tata Motors last week. This means that the car has met all the specified criteria for roadworthiness laid out by the government including emissions or noise & vibration and can now ply on Indian roads.
When Ratan Tata announced the Tata Nano project, there were a lot of scepticism over its cost target as well as technical specifications. But the road-worthiness test has now proved that the Nano will be the most fuel efficient car in India. The Nano is fitted with a twin-cylinder 623 cc rear mounted petrol engine that generates 33 horse power. Those dimensions make it the smallest engine in India. The Nano scored around 24 kilometers per litre during the homologation tests with ARAI.
Sources says that Nano is expected to deliver a standard mileage of over 20 kmpl when it actually rolls out on Indian roads. This would make it more fuel efficient than the Maruti Alto small car, currently top of the mileage heap.
More than 100 tests are done on Nano at the ARAI Pune facility over a period of four months to check the efficiency. It conforms to Euro IV emission standards which will come into effect in India in 2010. Nano is now technically ready to be sold in India. As part of the Central Motor Vehicle Rules (CMVR), all vehicles that ply on Indian roads, including the totally imported ones, have to be homologated for the local market.
