It was Lotus' Colin Chapman who famously coined this phrase, but Porsche's engineers turned the concept into a science and, during the 1960s, few manufacturers could rival Porsche's knowledge of lightweight metals, alloys and glass-reinforced plastics. Like its predecessors, the 909 Bergspyder used an aluminium spaceframe chassis and exotic titanium was then used for various suspension components, including the four coil springs. The engineers even experimented with alloy steering arms, but...

'What has always fascinated me more than anything else about racecar engineering, in its broadest concepts, is the combination of art - in terms of the ideas - and the test of those ideas, against well established physical principles. Having a great idea in itself is no use if it doesn't stand up to the harsh test of the physics. And, of course, we have to adapt ideas to any changes in regulations and sometimes, as in the case of a new tyre manufacturer, we don't always know quite what we've...

Case Study

In 2009, Toyota engineers wanted to study the wake behind the front wheels of the TF109 based on the average of all 300 data sets. The corresponding CFD result was then also imported into the same software so Toyota engineers could compare the two data sets and determine how accurate their CFD methods were. Whenever necessary, the engineers tweaked the CFD process to get it closer to the PIV wind tunnel results. In the case of the separation point on the front tyres, initial tests showed the...

Declaring The Variables

If we look a bit closer at how a typical advanced mathematics channel or program would be built up, it is very similar to popular programming languages. We start by declaring the variable we will be calculating, followed by a list of data channels we wish to use in the calculation. This could be anything the data system is currently logging. Next we need to declare all the constants we wish to use. Normally, these are handled separately and, in this example, the advanced mathematics package in...

Faster Processing

Fundamentally, there are only two ways to speed up a computer. You can increase the system clock frequency by improvements in silicon technology, thereby processing information faster, or you can attempt to do more processing in each cycle, effectively doing work in parallel.

But from 1985 to the turn of the century, the computer...

In addition to the extreme weight saving measures, the 909 Bergspyder's packaging also broke new ground.
