Tata Motors launches new Indigo e-CS with mileage of 25Kmpl

New Indigo e-CS

The Tata Indigo eCS Compact Sedan, which has been the pioneer of compact sedans in India, has gotten yet another upgrade from Tata Motors Limited. This time around, Tata motors have made the already fuel efficient sedan, even more fuel efficient with a raft of changes to boost the fuel economy number further. Now, the Tata Indigo eCS Diesel is touted to deliver a stunning 25 KMPL, thus making it the most efficient sedan in India.

It sports the all new CR4 Common Rail Diesel engine that has a displacement of 1396 cc delivering 70 PS @ 4000 RPM. With a higher torque of 140 NM at a lower 1800-3000 RPM, improvements in gear ratios, clutch-to-start and reduction in the weight of the car by around 10 kg, the Tata Indigo e-CS VX ensures better pickup. The Tata Indigo e-CS VX is also available with the MPFi petrol engine. Both these engines are compliant with BS4 emission norms.

How has Tata managed to squeeze an astounding 25 KMPL from the Tata Indigo eCS Diesel?

Tata Motors attributes the higher fuel efficiency of the 1.4 Liter TDI common rail turbodiesel to five main factors. 

1. The 1.4 liter turbodiesel engine’s ECU is said to have been optimized for maximum fuel economy. The company stated that the new car has features like SMART EMS (Engine Management System) CHIP that involves perfectly calibrating engine components every micro second to optimise functionality -- right from valve timing to compression ratios, to pressure volume ratios, to air fuel mixture, flawlessly synchronising every engine function to deliver 25 kmpl mileage.
2. The company also claims an innovatively designed engine head, block and piston assembly that ensures effective intake and circulation of charge (mixture of air and fuel), thereby minimising pumping friction losses. The result is maximum combustion of charge, increased efficiency and power.
3. The Indigo e-CS aerodynamics are said to have been improved to reduce drag. Tata says that the wheel arches have been redesigned and the body shell has been lightened to make the Indigo eCS a little more aerodynamic.
4. The gear ratios of the Indigo eCS has been altered for better driveability and economy. 
5. The Indigo eCS now gets low resistance tyres to reduce rolling resistance to a bare minimum, thus contributing to a higher fuel economy. So, all these changes have helped the fuel economy number of the Indigo eCS Compact Sedan go up by 2 KMPL, from 23 to 25 KMPL.

Other class defining features in the Tata Indigo e-CX VX are stylish R14 alloy wheels, satin finish front grill, headlamps and ORVM with blinkers. They, coupled with body coloured bumpers and chrome inserts on the rub rails, endow it with head turning looks. The interiors have been enriched with dual-tone beige seating and dashboard, premium wood-finish centre console, new instrument cluster with chrome rings and rear centre armrest for enhanced comfort. The plushness is enhanced with keyless entry, ABS, Bluetooth connectivity and electrical controls for ORVMs, besides carrying forward the comfortable AC, power steering and power windows. The car comes with a warranty of 18 months and unlimited kms, for private usage.

Diesel cars have been the flavor of the season and hence this high economy number is a great selling point for Tata. On whether these changes will actually translate into an actual increase in sales is something that we’ll find out in the coming months’ sales numbers. The Tata Indigo eCS Sedan’s VX diesel version is available at an ex-showroom Delhi price of INR 5.8 Lakhs while the top end petrol version comes in at INR 4.97 Lakhs.
