The Duratec 30, also known as the Mondeo V6 or the Mazda AJ engine is a 3.0-liter naturally aspirated six-cylinder from Ford Motor used to power midsize cars and sport utility vehicles, also known as SUVs. Featuring a dual overhead cam (DOHC) design, in a V configuration, the Ford Duratec 30 engine has been part of the Ford Duratec engine family since 1996.

This engine was developed in partnership with Mazda (part of the AJ family), but under Ford ownership, which explains why it was used in a variety of different vehicle applications from one brand to the next.  This engine, which shares several components with the Duratec 25 engine, or also known as the Mazda GY architecture, has also been used to power vehicles at Jaguar (known as the AJ) in other markets.

The Ford 3.0L Duratec 30 engine received many technological firsts for its time thanks to inputs from Porsche and Cosworth. Components like an aluminum engine block and cylinder heads were all standard, as well as cylinders lined with cast iron and a sequential fuel injection system, as well as fracture-split forged powder metal connecting rods and an assembled cast aluminum intake manifold.

In 2006, the engine received an important update by way of variable valve timing (VVT), further increasing horsepower and torque outputs. The Ford Duratec 30 engine powers the following vehicles:

  • Ford Escape
  • Ford Five Hundred
  • Ford Freestyle
  • Ford Fusion
  • Ford Taurus
  • Lincoln Zephyr
  • Mercury Mariner
  • Mercury Milan
  • Mercury Montego
  • Mercury Sable
