Tata Motors has sold 4 lakh sedans in India since the launch of the Indigo back in the early 2000's. We've seen all kinds of variants over the years. The Indigo with turbocharger and intercooler, Indigo DICOR with the CRDI engine, Indigo CS with TDI engine, Indigo CS with DICOR engine, Indigo XL with DICOR engine, Indigo XL with a really responsive 100bhp petrol engine and all other Indigos except for XL with smaller petrol engines.
Two years ago the Indigo range expanded with the addition of Manza that comes with 1.3-liter diesel and 1.4-liter petrol engine. IAB was first to report on the Manza CS which should accelerate sales past 5 lakh units.
