The 2.7-liter V6  Hyundai G6BA  engine was assembled at an enterprise in Korea from 1999 to 2012 and was installed on top versions of such popular models as Sonata, Magentis, Santa Fe, Tucson. There was a gas modification of this power unit under its own index L6BA.

In 1999, Hyundai introduced its own V6 unit to replace the G6AV engine, which was essentially a clone of the 24-valve version of the 2.5-liter Mitsubishi 6G73 engine. Of the differences here is an aluminum cylinder block with a closed cooling jacket, as well as a different timing belt: the belt rotates the intake camshafts, and the exhaust camshafts are connected to them by a chain.

Otherwise, it is the same V-shaped 6-cylinder unit with a 60° camber angle, a pair of aluminum DOHC heads with hydraulic lifters, a modern ignition system and an intake manifold, which received a proprietary VIS-type geometry change system.

The Delta family also includes engines: G6BP and G6BV.

• Hyundai Coupe 2 (GK) in 2001 – 2008;
• Hyundai Sonata 4 (EF) in 2001 – 2012;
• Hyundai Santa Fe 1 (SM) in 2000 – 2012;
• Hyundai Tucson 1 (JM) in 2004 – 2009;
