Anzeige

Porsche-911-RSR-991 Cockpit InnenraumDer heißeste Porsche aller Zeiten – zumindest was den 911er betrifft – ist ganz sicher der neue Porsche 911 RSR (991), den die Schwaben gerade auf der Los Angeles Auto Show präsentieren. Sein Debüt wird der neue 911 RSR beim 24-Stunden Rennen Daytona, im January 2017 feiern. Das Rennauto ist komplett neu aufgebaut.

Das fängt beim Chassis an, geht über das aerodynamische Luftleitsystem (monstermäßiger Diffuser am Heck), die Dämpfer – sogar Motor und Getriebe wurde komplett neu designt. Erstmals hat ein reiner Rennwagen auch Assistenten in Form einer Kollisionswarnung an Bord. Gerade nachts beim 24-Stunden Renner ein enormer Sicherheitsgewinn.

Für alle, die alles zum neuen 911 RSR (991) Rennwagen wissen möchten, hier die technischen Daten (englisch) – kein Bock das alles zu übersetzen!
