Whereas in the past decade, the CO2 reduction was the major driver for technology development with Gasoline engines, especially after the “Dieselgate” an “Extended Emission Compliance” including Real Drive Emissions is taking significant impact on future (powertrain development) technology routes. The RDE legislation initially was targeted primarily towards the Diesel-NOx and the Gasoline-PN emissions, now the requirements for meeting the forthcoming CO2 targets of 2020 resp. 2025 getting more into focus. To comply with these future CO2 and emission legislations, increasingly complex and costly technologies and technology combinations have to be applied. To overcome the typical trade-off between performance, fuel consumption and emission of current combustion engines, Variable Compression Ratio (VCR) is the next logical step. On a systems perspective, Hybridization gives add-on benefits, however, might also cannibalize the benefits of VCR. Thus, in spite the fact that VCR and Hybridization gain their fuel economy benefits by quite different physical basics, in view of most cost effective CO2 reduction, low cost Hybrid solutions like 48V systems might become real competitors to VCR. The paper will show some ideas how 48V Hybrid systems may be introduced to next generation of passenger cars with gasoline engine.
