The new Tata Indigo e-CS VX's mileage of 25kmpl has been certified by the Automotive Research Association of India (ARAI). This mileage has been achieved by reducing the weight of the car too..

The Tata Motors press release has listed five technological advancements that have helped reduce the new indigo's mileage.

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.

MAXIMUM CHARGE COMBUSTION - 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.

DRAG REDUCTION - Redesigned wheel arches and subtle alterations on the exteriors, combined with a lighter shell and engine, have collectively contributed to making the car more aerodynamic, reducing the drag coefficient.

TRANSAXLE (Gear Box) - With optimised Gear ratios to give best fuel efficiency and driveability together.

TYRES - For drag / rolling losses reduction, optimised tyres were developed which provide low rolling losses coupled with good riding comfort and handling.
