DutchEVO, safe or susta<strong>in</strong>able?<br />
had a certa<strong>in</strong> freedom to change requirements as the project proceeded. If the<br />
car was <strong>design</strong>ed to be used on European roads <strong>in</strong> the near future the constra<strong>in</strong>ts<br />
on the <strong>design</strong> would become more str<strong>in</strong>gent. Such constra<strong>in</strong>ts <strong>in</strong>clude pric<strong>in</strong>g,<br />
exist<strong>in</strong>g legislation, image, market<strong>in</strong>g <strong>and</strong> br<strong>and</strong> portfolio arguments, all of<br />
which play a large part <strong>in</strong> commercial car <strong>design</strong>. In the DutchEVO case, these<br />
arguments did not have a role.<br />
I started follow<strong>in</strong>g the DutchEVO project <strong>in</strong> May 2000, one year after the start<br />
up. I there<strong>for</strong>e had to rely on exist<strong>in</strong>g documents <strong>and</strong> <strong>in</strong>terviews to obta<strong>in</strong><br />
<strong>in</strong><strong>for</strong>mation about the start of the project.<br />
Design requirements<br />
In what follows, the <strong>design</strong> requirements, as <strong>for</strong>mulated <strong>in</strong> the <strong>design</strong> document<br />
‘DutchEVO the development of an ultralight susta<strong>in</strong>able conceptcar’, are quoted<br />
[Knoppert <strong>and</strong> Porcelijn, 1999]. This <strong>design</strong> document was written after the<br />
<strong>design</strong> work had started. The <strong>in</strong>itial aims of the project were:<br />
-‘To <strong>design</strong> a susta<strong>in</strong>able compact family car <strong>for</strong> use <strong>in</strong> <strong>and</strong> around<br />
Western European cities after the year 2009,<br />
-to show that it is possible to create a susta<strong>in</strong>able <strong>and</strong> af<strong>for</strong>dable car <strong>for</strong><br />
mass production,<br />
- to <strong>design</strong> a means of transportation unrestricted by exist<strong>in</strong>g <strong>design</strong>,<br />
image, structure <strong>and</strong> production philosophies,<br />
- to create an <strong>in</strong>tegrated <strong>design</strong> <strong>and</strong> giv<strong>in</strong>g priority to weight, safety,<br />
cost, volume <strong>and</strong> com<strong>for</strong>t <strong>in</strong> this order. {Knoppert en Porcelijn, 1999]’<br />
A list of <strong>design</strong> requirements <strong>for</strong> the DutchEVO is given <strong>in</strong> table 4.1 below.<br />

Later on <strong>in</strong> the <strong>design</strong> process it was decided that this eng<strong>in</strong>e should be comb<strong>in</strong>ed with a light<br />
hybrid system that recovers brak<strong>in</strong>g energy.<br />
