Template:Infobox automobile engine The Hyundai Sigma engine is what Hyundai Motor Company called the Mitsubishi 6G7 engine when manufactured in South Korea. It is a series of V6 piston engines.[1] The Sigma engine family began life with the simple V6 name.[2][3] Displacement ranges from Template:Cvt.
Script error: No such module "anchor". 2.5L (G6AV)
The DOHC G6AV (also called the 2.5 D, "D" for DOHC) is the small Template:Cvt version. Bore is Template:Cvt and stroke is shared with the Template:Cvt at Template:Cvt. Output is Template:Cvt at 6,000 rpm and Template:Cvt at 4,500 rpm.
Applications
- Hyundai Dynasty (1997–2005)
- Hyundai Grandeur (LX) (1995–1998)
- Hyundai Marcia (1995–1998)
Script error: No such module "anchor". 3.0L (G6AT/G6CT)
The DOHC G6AT and G6CT (also called the 3.0 D, "D" for DOHC) both displace Template:Cvt. They share the 2.5's Template:Cvt stroke but use a larger Template:Cvt bore. Output for the older G6AT is Template:Cvt at 6,000 rpm and Template:Cvt at 4,000–4,500 rpm, while the G6CT produces Template:Cvt at 5,500–6,000 rpm and Template:Cvt at 3,500–4,000 rpm.
The older SOHC G6AT 3.0 S produces just Template:Cvt at 5,000 rpm and Template:Cvt at 2,500–3,000 rpm.
Applications
- Hyundai Dynasty (1996–2005)
- Hyundai Equus (LZ) (1999–2005)
- Hyundai Galloper (1994–2000)
- Hyundai Grandeur (1989–2005)
- Hyundai Sonata (Y3) (1990–1998)
- Hyundai Starex (A1) (1999–2003)
- Hyundai XG300 (2001)
- Kia Opirus (2003–2006)
Script error: No such module "anchor". 3.0L LPG (L6AT)
The L6AT displace Template:Cvt. They share the 2.5's Template:Cvt stroke but use a larger Template:Cvt bore. Output is Template:Cvt at 4,500 rpm and Template:Cvt at 2,500 rpm.
Applications
- Hyundai Galloper (1998–2003)
- Hyundai Libero (2000–2007)
- Hyundai Starex (A1) (1999–2003)
Script error: No such module "anchor". 3.5L (G6AU/G6CU)
The G6AU and G6CU (both also called the 3.5 D ) are the large Template:Cvt versions of the Sigma engine. Bore and stroke are both larger at Template:Cvt, respectively. Output is Template:Cvt at 5,500 rpm and Template:Cvt at 4,000 rpm for the older G6AU and Template:Cvt at 5,500–6,000 rpm and Template:Cvt at 3,500 rpm for the newer G6CU.
The 3.5 D has a cast iron engine block and aluminum DOHC cylinder heads. It uses Multi-port fuel injection, has 4 valves per cylinder, and features forged steel connecting rods. It is designed to run on "regular" unleaded gasoline rather than the premium fuel used in many other high-output V6 engines.
The US-market version produces Template:Cvt at 5,500 rpm with Template:Cvt of torque at 3,500 rpm. It was introduced with the Kia Sedona minivan in 2001.
Applications
- Hyundai Dynasty (1996–1999)
- Hyundai Equus (LZ) (1999–2005)
- Hyundai Grandeur (1994–1996, 2002–2005)
- Hyundai Santa Fe (SM) (2002–2005)
