- The introduction of BSVI emission directives, upcoming CAFE regulations , ever increasing cost of fuel in the Indian Market have been bringing more focus and R & D efforts into improving engine efficiency, fuel economy, performance and reducing CO2 emissions. WLTP (Worldwide Harmonised Light Vehicle Test Procedure) emissions regulation will be introduced in the Indian Market from 2021, including WLTC (Worldwide harmonized Light Vehicles Test Cycles) and RDE (Real Driving Emissions). Active Grille Shutter (AGS) design and implementation has been discussed in this paper, a work that Tata Motors European Technical Centre has lead for Tata Motors and we have found that it improves the vehicle fuel economy in the real world. This work has been a part of the bouquet of programmes Tata Motors European Technical Centre (TMETC) is championing as a part of the new vehicle and powertrain technology introduction. The programme of work include vehicle efficiency, fuel economy improvement, starting from optimising current energy balance, vehicle level performance, investigation of parasitic losses and introducing technologies which can crawl back losses, increase the efficiency thereby improving real world fuel economy whilst reducing emissions.
