The 6G7x family of engines is a series of 60 º V6 engines designed by Mitsubishi for a variety of applications. The 6G7x has been used in front, rear and all-wheel drive applications. As with the Sirius family there can be many variants within a single model of enigne.

All variants feature a cast iron engine block and alluminium cylinder heads with belt driven overhead camshafts.

As with many other Mitsubishi engine families, the 6G7x was also used in Hyundai and Chrysler vehicles.

The 6G72 has been produced in many different variants. It is a 3.0L V6 displacing 2972cc and has a 91.1mm bore and 76 mm stroke. All versions featured roller rockers and a one piece main bearing assembly.

The single overhead cam 12 valve (2 per cylinder) version was used in the Second Generation Magna/Verada and the single overhead cam 24 valve (4 per cylinder) version was used in the Third Generation Magna/Verada. For information on these engines see their respective pages.

There have been versions of the 6G72 which have been produced with double overhead camshafts with 24 valves, twin turbochargers and double overhead camshafts with MIVEC. Some versions also feature Mitsubishi Variable Intake Control.

When used by Hyundai the SOHC version was called G6AT (3.0S) and the DOHC version was known as G6HA (3.0D) or G6HCX

In Australia the engine has been used in:

  • 6G72 SOHC 12v: Second Generation Mitsubishi Magna/Verada, Mitsubishi Pajero, Mitsubishi Triton, Mitsubishi Starwagon, Hyundai Sonata
  • 6G72 SOHC 24v: Third Generation Mitsubishi Magna, Mitsubishi Triton, Mitsubishi Challenger.
  • 6G72 DOHC 24v: Hyundai Sonata, Hyundai Grandeur
