The Mitsubishi Orion or 4G1 engine is a series of inline-four internal combustion engines introduced by Mitsubishi Motors in around 1977, along with the Astron, Sirius, and Saturn. It was first introduced in the Colt and Colt-derived models in 1978. Displacement ranges from . The Orion replaced the earlier Neptune engine and carried over that engines overall layout and crossflow design. Unlike the near-square Neptune, however, the Orion was a long-stroke design.

4G11

The 4G11 displaces with a bore and stroke of . This design utilized Mitsubishi's new lean burn MCA-Jet technology, with a head which included a tiny second inlet valve which created a swirl, allowing for combustion of a much leaner fuel mixture. The diameter of the blades in this charger is rather small, at 49 mm, and it spins at 90,000 rpm to provide of boost. This increased power and torque by about 30 and 25 percent respectively.

4G13

The SOHC, 12 & 16 valve 4G13 displaces and produces with a bore and stroke of . In the Gulf Countries, gross at 6000 rpm is claimed on the Mitsubishi Lancer CB1. The 4G13 engine has been produced by Dongan Mitsubishi Motors Engine Manufacturing, in Harbin, China since September 1998.
