Following up on our look at the Tata tally back in November, the “people’s car” has finally been officially unveiled.

India’s Tata Motors Ltd unveiled the world’s cheapest new car on Thursday, bringing car ownership closer for millions of poorer consumers in emerging markets but raising environmental concerns. The 4-seater Nano, with an engine around 625cc, will have a dealer price of 100,000 rupees ($2,500), about half the cost of the cheapest car on today’s market, a 25-year old model from Maruti Suzuki Ltd, Tata’s great rival. The Nano will go on sale later this year, the company said.

The car is expected to give a mileage of about 20 kilometers per liter (50 miles to the gallon), which is great. And lots more people will have access to personal transportation, which is also good. But wait a minute, everyone using a car is bad. We’re so confused.
