Using aerodynamics simulation to optimize for pending WLTP requirements
Thursday, February 16, 2017

With the shift to improved procedures for fuel consumption and CO2 emissions, a new Worldwide Harmonized Light Vehicle Test Procedure (WLTP) has been developed by the United Nations. The aim of WLTP is to more accurately reflect real-world driving and harmonize emissions testing across the globe. The new testing procedure will begin in 2017 and roll through 2018 in different stages.

One key impact of the WLTP is the calculation of fuel consumption/emissions will not just focus on vehicle, engine and transmissions. Engineers will now need to include any special equipment and the weight changes these options add to the vehicle. For vehicle aerodynamics specifically, there will be a higher burden on design and testing as engineers will now have to move beyond baseline drag and consider all available vehicle configurations. 

This On-Demand webinar will highlight methods to help reduce this burden, cost and turnaround time. Presenters demonstrate how OEMs can predict fuel consumption/emissions by simulating real-world test conditions using a digital twin of the actual geometry. This will enable the vehicle to be optimized for the new standards and to realistically meet strict government regulations prior to the first hardware build.

Experts examine where CFD is today in supporting vehicle aerodynamics and then lay out a future for leveraging digital technology to realistically and cost effectively meet the WLTP guidelines.
