The 6G7 or Cyclone V6 engine is a series of V6 piston engines from Mitsubishi Motors. Five displacement variants have been produced from 1986 to present day, with both SOHC and DOHC layouts. While MIVEC variable valve timing has also been implemented in some versions. The 2.5 and 3.0 L versions were also available with gasoline direct injection.

The 6G71 model featured SOHC and produced 88 kW (120 PS; 118 hp) at 5,500 rpm and 172 N·m (127 lbf·ft) at 4,500 rpm. It was installed with two valves per cylinder, and used Mitsubishi's ECI-Multi multiple port fuel injection fuel delivery system. The compression ratio was 8.9:1. An earlier version, with single-point fuel injection, only had 105 PS (77 kW) at 5,000 rpm and 16.1 kg·m (158 N·m; 116 lb·ft) at 4,000 rpm.

A supercharger was installed and exclusive to the Debonair. It produces 150 PS (110 kW) at 5,000 rpm and 221 N·m (163 lbf·ft) at 3,000 rpm. The compression ratio for the supercharged model is 8.0:1. The 6G71 engine was also converted to run on LPG, a version which was only available to the Debonair and mainly intended for commercial (taxi) use.

The 6G72 was manufactured in three different models which featured SOHC with 12-valves, SOHC with 24-valve, and DOHC with 24-valves.

The latest version was used in the Mitsubishi Eclipse GT and Galant. Output in 2004 was 210 hp (157 kW; 213 PS) at 5500 rpm with 278 N·m (205 lbf·ft) of torque at 4000 rpm. In the older version, used in many Chrysler models since 1987 this V6 was a SOHC 12-valve developing 141 hp (105 kW) at 5000 rpm and 172 lb·ft (233 N·m) of torque at 3600 rpm. The Mitsubishi models were with a 3.0 Litre 6G72 engine SOHC 24-valve developing 195 hp (145 kW) at 5000 rpm and 205 lb·ft (278 N·m) of torque at 4000 rpm.For the MIVEC engine output is 201 kW (273 PS; 270 hp) at 6000 and 304 N·m (224 lbf·ft) at 4500.
