Biturbo II and IIS

 
 

 
 

 

 
 

   
 

The Biturbo II was fundamentally a face-lifted version of its predecessor.  The standard car retained the same engine output, whilst that of the 'S' was increased marginally.  There were some changes in the suspension of both cars.  The most interesting change was the adoption of the Sensitork differential which made the anti-locking effect more efficient by transferring up to 90% of unused power to the relevant wheel.
