/ 9 Emission and CO2 EFFICIENT REDUCTION OF REAL DRIVING EMISSIONS ��emonstrating compliance with the emission limits for passenger cars under real-world driving conditions re��uires not only a new generation of porta��le measurement systems, ��ut also a totally new methodology for developing powertrains and vehicles. AVL provides e��cellent support in ��oth areas. The Euro 6c Emission Standards, to ��e introduced in 2017, re��uire that passenger cars and lightduty vehicles prove compliance with emission limits under real-world driving conditions. For OEMs, ensuring compliance with ��Real ��riving Emissions�� ��R��E�� presents a major challenge. While it used to ��e sufficient to optimize emissions within the legally re��uired cycles, it is now re��uired not only to tune the vehicle��s entire operating range to optimally fit the emission limits, ��ut also to make sure that the adjustments are just as functional for standard conditions as they would ��e for a ��road range of routes ��ur��an, countryside, highways, etc.��, traffic situations or any kind of weather or road conditions ��heat, cold, rain��. The impact of different driver types additionally needs to ��e considered. The standard development methodology has started to reach its limits, ��ecause one would re��uire a disproportionately high num��er of test runs to fully cover all driving situations. A solution to the pro��lem is offered ��y model-��ased development that optimizes the development tasks considera��ly ��y employing physical/empirical models for the engine, e��haust gas aftertreatment and the entire system. R��E also re��uires a new generation of porta��le emissions measurement systems ��PEMS��.
