Tata  Motors has rolled up its sleeves and is playing the fuel efficiency  card again. After the launch of the Indica eV2, next up on the cards to  be launched by Tata Motors is Indigo e-CS VX a saloon that claims to be  the most fuel efficient in sedan segment. Tata Indigo E-CS VX provides a  mileage of 25 kmpl which is certified by ARAI (Automotive Research  Association of India ) . Tata Indigo E-CS VX price with the fuel  injected petrol motor (both engines being BS4 compliant) is tagged at  Rs. 497,727 while the CR4 diesel is priced at Rs. 580,339 (all prices  ex-showroom Delhi). Both these engines are compliant with BS4 emission  norms.
Tata Indigo e-CS VX specifications reveals that it is  powered by 1396 cc CR4 common rail diesel motor which produces a power  of 69 bhp at 4000 rpm and a peak torque of 14.2 kgm at 1800-3000 rpm.  The overall weight of the car has been reduced by around 10 kg and  improvements have been made to the gear ratios all of which result in  the e-CS' astounding mileage figure! Changes have also been made to the  ECU, which is now optimised for fuel efficiency. Apart from the  mechanical changes, some cosmetic changes in the form of redesigned  wheel arches, a satin finish front grille, head-lamps and ORVMs with  blinkers sum up the changes made to the e-CS. Lastly, the e-CS has 14"  alloy wheels with low rolling resistance tyres which provides extra bit  of efficiency. Tata Indigo E-CS VX features this sedan with Wooden  Centre Console ,Keyless Entry, bluetooth, rear centre armrest.
Tata  Indigo E-CS VX mileage is so good due to a lot of features in its  engine like smart ems (Engine Management System) which is a chip that  involves perfectly calibrating engine components every micro second to  optimize functionality, right from valve timing to compression ratios,  to pressure volume ratios, to air fuel mixture, flawlessly synchronizing  every engine function to deliver 25 kmpl mileage, maximum charge  combustion 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 .As the wheel arches are redesigned and subtle alterations are  done on the exteriors along with a lighter shell and engine, so they  have contributed to making the car more aerodynamic by reducing the drag  coefficient. Transaxle is another reason for better mileage which  optimizes gear ratios. Optimised tyres were developed which provide low  rolling losses coupled with good riding comfort and handling.
