The Indigo is Tata's entry level sedan. If you want a simple basic sedan with a diesel poweplant, you might want to give this a try. Just in case you were wondering, dual-airbags and ABS are standard.
Under the hood is a 1.4 liter diesel, it might produce only 69hp, but it produces a decent 135Nm of torque which should be sufficient for a little sedan like the Indigo. This engine is mated to a 5-speed manual transmission.
