Biturbo 420 / S

 
 

 
 

 

 
 

 

 
 

   
 

Produced for the domestic market which suffered under the VAT super tax, the 420, other than for the size of the engine, was identical to the 425 which continued to be sold for export.  The 420S had improved handling and performance and similarly to previous versions was equipped with two intercoolers.
