Proposal for modifications to the calculation parameter/coefficients r0, a1 and b1 prepared by the WLTP downscaling issues task force.
#5: Modifications of the calculation parameter/coefficients r0, a1 and b1 (WLTP-08-10e)
India requested modifications and made a respective proposal. Modified calculation parameter/coefficients were developed. Effects for M1 and N1 vehicles were shown. O. Eberhardt expressed his concerns; if the approach would probably apply to N1 vehicles on the European market in future (note: this is not the case today). Proposed parameters were supported by India, JPN, EC as a compromise solution and adopted by WLTP IWG.
