CONCEPTS, MULES & PROTOTYPES

Before any new model goes into manufacture the design – in various stages of finalisation – has to go through practical Kitesting. These vehicles are prototypes y by , recognisably l P & and orsche most often visually identical to the subsequent production vehicle. Far less frequently these days, where more extensive research and dynamic development can be carried out with software simulations, a manufacturer experiments with a radical new idea by building some of the technology into the preceding model. These cars are often referred to as ‘mules’. In the past, the need to keep particular experiments confidential even led to some mules wearing total disguises to fool both press and competitors. Examples of this at Porsche include the Audi 100 Coupe, into which Weissach shoehorned the 928’s V8 and running gear; later the 928’s innards would also be built into an Opel Diplomat.

Concepts are used by manufacturers to float an idea, to test acceptability of a particular design or style. A phenomenon which in today’s homogenised and regulated auto industry has become unusual, the most successful example in Porsche history was the Boxster concept, greeted with standing ovations when it was revealed in 1993. That the resultant Boxster – which would closely prefigure the new 911 – was so similar to the concept was a tribute to Porsche’s original design, achieving homologation with a minimum of compromises which usually dilute and sometimes completely spoil the original idea.

The real workhorses of pre-production are, of course, the prototypes, masked these days if their makers want to hide them by an astute application of chequered tape, which brilliantly sabotages visual perspective. Of the thousands of prototypes built, virtually all
