Six Degrees of Innovation: The Space-saving Air Conditioning Unit

Space-saving Air Conditioning Unit

Innovation No4:

In most cars the air conditioning/heater unit is a bulky component, housed behind the dashboard in front of the front seat passenger. Toyota engineers recognised that if they could make it smaller, it could be repositioned, freeing up valuable leg and knee room in the front section of the cabin.

They succeeded in their challenge, not only reducing the unitís dimensions by 20 per cent overall, but also maintaining its performance quality. Rerouting the internal passages improved airflow and a more compact filter was used, alterations which in turn meant a smaller blower fan could be adopted.

As a result, the passenger side of the dashboard is slimmer than that in front of the driver, and is positioned further forward and towards the centre of the windscreen. This gives the dashboard an asymmetrical shape, a feature that will be the subject of the next iQ innovations bulletin.
