Endlich ein gelungener Porsche Umbau

  • OPEL MANTA A: PORSCHE 924 DEVELOPMENT MULE


    von Opel Owners' Register of Malaysia, Donnerstag, 28. Oktober 2010 um 15:40 ·



    When
    Porsche was developing the 914N (924, the 914's replacement) in 1972,
    they first fitted the entire 924 drivetrain and suspension into a used
    BMW 1600 in April 1972.The intended running gear was adapted to the car.
    VW-Audi's LT 4-cylinder engine fitted with a carburettor, developing
    95bhp was installed. This BMW was code-numbered 914N, meaning 914
    successor. It went onto the rolling road in October and tests on noise,
    air-flow, engine cooling, transmission efficiency and emissions were
    completed.

    Shortly thereafter they added an Opel Manta
    to their test mule fleet. Designated W1, the Manta had the full
    924-specification underfloor including the MacPherson-strut front
    suspension and VW Super Beetle derived, torsion bar suspended
    semi-trailing arms at the rear.



    Brakes,
    discs at the front and drums a the rear came from VW's parts
    department, as did the rack-and-pinion steering, door handles, switches
    and various other small items. Noteworthy in the test-mule Manta is the
    Bosch fuel-injected 2-litre engine powering it, rated at 125bhp.

    In
    this fashion, the Porsche 924 floorpan, powertrain, braking and
    suspension systems were tested in the Algerian desert, racking up nearly
    ten thousand kilometres, disguised all the time, as an Opel Manta A!

    Porsche 924 Prototype Production- Production: 8+6- Production date: 1972 to 1975

    Notes
    - The EA425 project was initiated in January 1972.
    - EA425 was created by Porsche but owned by Volkswagen.
    - In 1974 EA425 was intended as the successor of the Audi's 100 Coupé S.
    - In 1975 Porsche become the responsible manufacturer of the 924 the successor of the 914.
    - A modified BMW 1600 or 2002 (914N or V1) in April-October 1972.
    - A modified Opel Manta (W1 or V2) October 1972.
    - Later another Manta (V3) had the complete 924 underbody, and was tested 6000 miles in the Algerian desert.
    - First 8 prototypes were built for testing from June 1973 to 1974.
    - 6 prototypes were built corresponding to the final design.
    - 56 pre-production 924s built at Neckarsulm October 1975 to December 1975.
    - About 100 pilot-build cars, full production started in November 1975.

    Schöner Beitrag.

    die Story und die technischen Details sind (mir) bekannt. Doch woher kommt die Angabe, wie viele Testwagen (nicht auf Basis Manta-A!!) mit der Technik des Porsche 924 gebaut wurden?

    Oder ist der Beitrag nur Facebook-Geplapper, dass alle stillschweigend zur Kenntnis nehmen? Wo ist der "aufklärende" Hintergrund?
