Comments of this past auction
Technik: Die Porsche-Ingenieure suchten für den 928 einen großvolumigen Motor. Prototypen wurden zunächst mit einem 5-Liter -V8-Motor mit 300 PS (220 kW ) ausgestattet. Es gab Diskussionen über den Einsatz eines 4,6-Liter-V10-Motors mit 90°-Zylinderwinkel und 88 mm Bohrungsabstand. Dieser Motor war eine Weiterentwicklung des Audi-Fünfzylinders (der auch im Lamborghini Gallardo zum Einsatz kam) und basierte auf dem Volkswagen-Motor EA827. Der Porsche-Vorstand lehnte diesen Vorschlag jedoch ab, da er Gerüchte über ein neues 911-Modell mit einem vorn eingebauten Volkswagen-Motor befeuern könnte. Zudem wird vermutet, dass der Vorstand eine gewisse Distanz zum Volkswagen-Konzern wahren wollte. Der so entstandene Vollaluminium- Motor M28 wies mehrere charakteristische Merkmale auf. Sein Zylinderabstand von 122 mm deutete auf die Verwendung dickwandiger Zylinderlaufbuchsen aus Aluminium ohne Stahleinsätze hin. Die Wassermäntel waren auffallend groß, was auf das Potenzial des Motors für den Rennsport schließen ließ. Um eine niedrige Motorhaube zu gewährleisten, wurde der Luftstrom optimiert, wodurch die Zündkerzen oben im Zylinderkopf platziert wurden. Die Vierbolzenlager waren massiv und wurden über Nuten in der Unterseite des Motorblocks mit Öl versorgt. Sie wurden von einer großen, einteiligen Struktur getragen, die den unteren Motorblock bildete. An dieser Struktur war die Ölwanne aus Aluminiumguss angeschraubt. LG Tom
