[Vwdiesel] winter fronts

[Drew MacPherson]

VW sold winter fronts for their A1 and A2 cars as Autobahn accessories.

The idea of blocking airflow through the rad has been around for a long
time - farm and construction equipment utilized mechanically controlled
louvres (or shutters) in front of the rad to help keep engines in the
optimal operating range.  These shutters were standard equipment on many
engines equipped to burn kerosense, and early diesels as well.
