Verlustleistungsreduzierung im Antriebsstrang eines Premium-SUV

Robert Plank; Dietmar Schwarzenthal

Gemeinsam haben Porsche und Schaeffler ein CO2-Demonstrationsfahrzeug auf der Basis eines Porsche Cayenne mit V8-Ottomotor aufgebaut. Durch neue optimierte Komponenten in Antriebsstrang und Fahrwerk konnte wahrend des Projekts CO2ncept-10% im Vergleich mit dem SUV-Serienfahrzeug der Kraftstoffverbrauch im NEFZ um zirka 10 % reduziert werden. Die Einsparung teilt sich im Verhaltnis 70:30 in den Einsatz energetisch optimierter Technologien und in die Reibungsreduzierung an Kontakten auf.

Power loss reduction in the powertrain of a premium SUV

Robert Plank; Dietmar Schwarzenthal

In a joint action, Porsche and Schaeffler developed a CO2 demonstration vehicle based on a Porsche Cayenne with a V8 SI engine. During the CO2ncept-10% project, new optimized components for powertrain and chassis enabled a reduction in NEDC fuel consumption of around 10 % compared with the volume produced SUV. The saving is split at a ratio of 70 to 30 in the utilization of technologies with optimized energy requirements and the reduction of friction on contacts respectively.
