2006 developments have culminated in the GV5 S2 variant.  The primary difference is a new cylinder head design and single piece casting has been introduced that has allowed a 20 kgs weight savings over the standard GV5.

In 2007 the GV5 S2's capacity was increased to 5.5 liters and the engine was renamed the GV5.5 S2.
