1971 Porsche 917/20 Le Mans 3 hour race, Drivers: Willi Kauhsen, Reinhold Joest. In the Porsche factory test colour scheme which most of their race cars started with. A simple black Porsche “schriftzug” on white.
4907cc 180° V12, 600hp/8300rpm
Top speed 355km/h
The so called “Big Bertha” because of its impressive girth. So wide was Bertha that it needed to be transported on a special Magirus truck. Unfortunately “Bertha Sau” as an aerodynamics experiment was not successful, it didn’t handle as expected and top speed was some 30km/h short of similarly engined 917LH models.
In the actual 1971 Le Mans poor old Bertha was crashed by Reinhold Joest. She survives today in the Porsche Museum resplendent in Anatole Lapine’s pink pig butchers paper livery. This colour scheme didn’t sit well with senior folks in Porsche (eg Piech) but garnered huge publicity. The public were captivated by the rotund looking 917/20.
1969 Porsche 917-001 Langheck
4494cc 180° V12 with 520hp/8000rpm
Top speed 340km/h
This was the one time livery when the car was shown at the announcement of the Porsche and JW Automotive Engineering collaboration at a hotel in London, then shown at Earls Court Motorshow and also another motor show in Vienna.
The aero trim tabs at the front were a bit of a failure. Although they helped with downforce they were frequently broken off due to “enemy contact” (impacts with other cars). At the back, the moving spoilers connected to the rear suspension didn’t work properly because the coke-bottle body shape at the back generated lift and minimised the effect of the spoilers. The original 1969 917 was a dangerous handling car. At high speeds it wandered across the track and would swerve unpredictably when going over crests or bumps. It’s fair to say that the drivers were scared of it. More recently Derek Bell declined to drive 917-005 (the rebuilt John Woolfe car) at Le Mans classic. Woolfe crashed and wrote off the car on the opening lap of the 1969 Le Mans and died in the accident. The car was subsequently rebuilt some years ago with the original chassis number.
Both are 1:18 scale.
Note: it is technically correct to call the engine 180° V12 due to its configuration. It doesn’t behave like a “boxer”.
